Farmers routinely determine irrigation requirements from visual observations and cultivation experience, but this can lead to under- or over-irrigation. To establish precise irrigation technology for strawberry cultivation, the average daily evapotranspiration and water requirements were estimated according to the environmental data: air temperature and humidity from the center of the greenhouses and solar radiation from outside greenhouses. Makkink FAO24 equations (temperature and cloudiness) were used to estimate the evapotranspiration and water requirements. The temperature equation showed higher correlation coefficients in solar radiation (R 2 = 0.60), evapotranspiration (R 2 = 0.76), and water requirements (R 2 = 0.69) than other tested equations. The daily irrigation, calculated from the estimated evapotranspiration, was 3.8 tons/10a. It is possible to develop a precision irrigation system from estimated evapotranspiration during the winter cultivation of “Seolhyang” strawberries in South Korea.

Vegetable crops production in the field and changes in physiological aspects of crops during the growing season may be affected by the increased temperatures associated with climate change. The objectives of this research were to evaluate the performance of an air temperature gradient using the computational fluid dynamics (CFD) technique and validation of performance throughout Kimchi cabbage growth and physiological responses to air temperature in a greenhouse temperature gradient (GTG). We simulated temperature differences with CFD in a semi-closed plastic tunnel, which is a GTG. The accuracy of CFD improved by vertical and horizontal temperature profiles was evaluated for the performances of a GTG. The growth of Kimchi cabbage was examined and validated using a temperature gradient within a GTG. Correlation coefficients of measured heights were 1.120, 0.597, and 0.459. Root mean square error was below 0.103, which means the CFD simulation values were highly accurate. The error analysis showed that it was possible to accurately predict temperature gradient changes within a GTG using CFD techniques. CFD results showed an average error of 0.597 °C compared to field monitoring results. The maximum temperature difference of the GTG was 5.7 °C, suggesting a well-controlled set point (6 °C difference between outside conditions and inside conditions of the GTG). On a cloudy day, the GTG set differential temperature (dT) was well maintained, while the accuracy of the GTG’s dT was degraded on sunny days because of interference by solar radiation. There was a significant difference in the growth, net photosynthetic rate, transpiration rate, and intercellular CO2 concentration along with temperature differences in the GTG. CFD can simulate temperature gradient distribution in a GTG and predict the temperature difference for equipment with different specifications. These facilities can be used in climate change-related studies, such as assessment of crop production area optimization, crop physiological response to temperature, vulnerability assessment of crop production under increasing temperatures, or extreme weather.

The objective of this study was to develop a growth model for grafted hot pepper seedlings as affected by air temperature and light intensity. After grafted union formation, the hot pepper seedlings were cultivated in various environmental factors in terms of four levels, mean daily air temperature (17, 22, 27, and 32 °C) and 3 levels of light intensity (150, 350, and 550 μmol·m−2·s−1). The growth traits were measured 0, 7, 14, 21, and 28 days after grafted union formation (DAGU). The plant height was improved, and development of leaves enhanced by higher air temperature. The number of leaves was greatest under the combination of the high temperature and high light intensity, resulting in 39.0/plant at 28 DAGU. The leaf area and dry weight showed 491.9 cm2/plant and 2.68 g/plant, respectively, at 28 DAGU under 32 °C air temperature and 550 μmol·m−2·s−1 light intensity. The changes of dry weight were rapidly increased under the higher air temperature and light intensity as followed by analysis of the growth curve. The beta distribution model was developed, and the relative growth rate (RGR) was simulated by the model, the maximum RGR was predicted at 0.116 g·g·d−1. The RGR showed 0.113, 0.127, and 0.109 g·g·d−1 at 10, 20, and 30 °C air temperature, respectively, and RGR was improved by 12% by increasing the air temperature by 10 °C, without going over 25 °C ADT. Results indicated that the developed growth model might be applied to optimal environmental control for maximized RGR of production of grafted hot pepper seedlings.

Each strawberry (Fragaria × ananassa) cultivar has its own growth and yield characteristics. However, the characteristics of many cultivars have not been determined at a consistent time and place, making direct comparative analysis difficult. The objective of this study was to identify characteristics and trends of five Korean strawberry cultivars in the same environment during an entire season. Therefore, environmental factors such as daily average air temperature, daily average relative humidity, daily average solar radiation, daily soil temperature, daily soil water content, daily soil electrical conductivity (EC), plant growth characteristics such as the number of leaves, plant height, leaf length, leaf width, and crown diameter, and productivity characteristics such as flowering and fruiting were measured to investigate the possible correlations of the data over one season. The vegetative growth of “Seolhyang” and “Keumsil” was greater than that of “Jukhyang” and “Maehyang”. The yield of “Arihyang” was greater than that of all other cultivars. “Arihyang” also presented the greatest weight per number of fruits. Among environmental factors, higher variability in air temperature and soil water content was correlated to lower total fresh weight in the following week at different degrees for each cultivar. Among the cultivars, the time to the first flowering was delayed by about seven days when the number of leaves increased by one and was reduced by one day per 1 cm increase in plant height. The total fresh weight was enhanced up to 271 g per experimental unit, while the average number of leaves increased by one. The results indicate that the data can be used by those who need information regarding the characteristics of the strawberry cultivars through direct comparative analysis.

The aim of this study was to develop and validate growth and photosynthetic models of Kimchi cabbages under extreme temperature conditions at different growth stages. Kimchi cabbage plants were subjected to low and high air temperatures 7–10 days after transplanting (DAT) and 40–43 DAT using extreme weather simulators. Except during these periods, the air temperature, relative humidity, solar radiation, and precipitation were set according to previous meteorological data. The experiments were performed over two years: in the first year, data were used to develop the models; the second-year experimental data were used for validation. The growth parameters and relative growth rate of Kimchi cabbage decreased due to low and high air temperature treatments. Photosynthetic CO2 response curves, which were measured using a portable gas exchange system, were used to calculate three biochemical parameters from measured data: photochemical efficiency, carboxylation conductance, and dark respiration. These parameters were used to develop the photosynthetic models (modified Thornley’s models) representing predictions of net photosynthetic rate by CO2 concentration and growth stage. The simulated photosynthetic rate with extreme high temperature treatment (35/31 °C) was 19.7 μmol m−2 s−1 which was evaluated approximately 3% deduction compared with control. Results of this study indicate that the growth and photosynthetic models developed here could be applied to evaluate retarded growth and net photosynthetic rate under extreme temperature conditions.

To verify the productivity of the autotrophic transplant production method (ATPM), a novel propagation method in a plant factory with artificial lighting for transplant production (T-PFAL), strawberry transplants were produced by the ATPM for 365 days. A total of 3497 transplants were produced by the ATPM over 365 days with nine propagules in a cultivation area of 3.6 m2 in the T-PFAL. When the simulated results were fit with the measured results, the propagation cycle timescales from planting propagules to producing the first, second, and third runner plants were 15, 27, and 43 days, respectively. The cumulative number of transplants (CNT) produced from 5, 10, and 20 initial propagules in a cultivation area of 36 m2 over 365 days was simulated by the verified program along with the propagation cycles, and these values were 27,970, 30,010, and 31,900, respectively. The simulated CNTs from nine initial propagules in 18 and 72 m2 over 365 days were 15,950 and 55,940, respectively. These results indicate that the ATPM is an appropriate propagation method to produce transplants rapidly in a T-PFAL, especially when the number of propagules or propagules is limited.

The texture of Kimchi cabbage was investigated by determining the hardness variation of midribs by leaf order and midrib position and analyzing the hardness characteristic by probe type. The objective of this research was the development of assessment methods for hardness of Kimchi cabbages in cropping types of summer season production. The hardness of the midrib of Kimchi cabbage leaves varied depending on the degree of development of the internal and external epidermis and the vascular tissues. The midrib hardness of Kimchi cabbage leaves did not differ significantly among cultivation types and tended to be lower toward the inner leaf. Using the Volodkevich bite jaws probe or blade set probe to measure the cutting force proved to be a suitable approach for examining the texture characteristic of Kimchi cabbage. The peak force of hardness in volodkevich bite jaw probe test the smallest distance and the second and third peak force intervals distance showed shortest among all the tested probes. In addition, hardness force tests with inside and outside results pattern was similar. When measuring the cutting force of midrib by these probes, it is preferable to measure from the outer epidermis to the inner epidermis of the leaf midrib, at 40–50 mm from the leaf stalk, on the 2nd to 6th outer leaves of Kimchi cabbage head formation.

This study investigated the effects of foliar applications, such as brassinosteroid (BR), methyl jasmonate (JA), salicylic acid (SA), and sodium nitroprusside (SNP), on the growth, yield, photosynthetic characteristics, and antioxidant enzyme activity of Kimchi cabbage (Brassica rapa L. ssp. pekinensis) exposed to heat stress. Kimchi cabbages were grown in extreme weather growth chambers under controlled conditions (air temperature, relative humidity, and solar radiation of the Daegwanryeong region, 37° 40′ N, 128° 32′ E). At 18 days after transplanting, Kimchi cabbages were treated with foliar application of biostimulants (vs. non-sprayed control) and exposed to heat stress (air temperature 30/25 °C) and mean daily air temperature under normal conditions (21.2 ± 1.6 °C day/night, respectively) for 5 days. The foliar application concentrations were 50, 100, and 200 nM BR; 50, 100, and 200 μM JA; 1, 2, and 4 mM SA; and 0.25, 0.50, and 1.00 mM SNP. At 38 days after foliar application, the shoot fresh weight of Kimchi cabbages treated with 200 nM BR was 2123 versus 1422 g plant−1 (control). The head weight and yield were the greatest with 2 mM SA treatment, which produced 3806 versus 2184 kg ha−1 (control). Heat stress induced a low photosynthetic rate in Kimchi cabbage, while foliar application of biostimulants enhanced photosynthesis recovery. During the 3 days after heat stress, catalase and peroxidase enzyme activities of Kimchi cabbage increased by 1.76- to 2.08-fold on average compared to the control. Results indicated that foliar application of biostimulants reduced physiological damage and enhanced the activity of the antioxidant enzymes, thereby improving heat stress tolerance in Kimchi cabbage.

This study investigated the effects of drought stress on Chinese cabbage (Chcab) by measuring plant growth responses, total antioxidant enzyme activities, the contents of bioactive compounds including glucosinolates (GLS, aliphatic and indolic), and binding with human serum albumin (HSA). Forty-day-old Chinese cabbage (Brassica rapa L. ssp. pekinensis) seedlings were transplanted into pots and maintained for three weeks at 10% (drought-treated, D-T) and 30% (control, C) soil water. The total leaf number, leaf area, and fresh and dry weights were significantly lower in D-T Chcab than in controls. Total GLSs and catalase activities were found to be significantly higher in D-T Chcab than in controls. Indolic GLSs were significantly higher than aliphatic GLSs in D-T Chcab. These results show that D-T Chcab reduced growth parameters and binding properties with HSA and influenced total contents of GLSs, polyphenols, flavonoids, total antioxidant enzyme activities, catalase and peroxidase.

In higher plants, several lines of evidence suggest that long non-coding RNAs (lncRNAs) may play important roles in the regulation of various biological processes by regulating gene expression. In this study, we identified a total of 521 lncRNAs, classified as intergenic, intronic, sense, and natural antisense lncRNAs, from RNA-seq data of drought-exposed tomato leaves. A further 244 drought-responsive tomato lncRNAs were predicted to be putative targets of 92 tomato miRNAs. Expression pattern and preliminary functional analysis of potential mRNA targets suggested that drought-responsive tomato lncRNAs play important roles in a variety of biological processes via lncRNA–mRNA co-expression. Taken together, these data present a comprehensive view of drought-responsive tomato lncRNAs that serve as a starting point for understanding the role of long intergenic non-coding RNAs in the regulatory mechanisms underlying drought responses in crops.

Alternative splicing (AS) is a post-transcriptional regulatory mechanism that expands proteomic diversity. AS often occurs in the context of changing environmental conditions. Nevertheless, it remains largely unknown whether or how AS is involved in plant responses to drought stress. To assess the effects of drought stress, we compared AS genes in tomato plants by constructing three RNA-seq libraries in normal and drought conditions. We identified 464 Stage 1 (normal condition)-specific, 512 Stage 2 (mild drought stress)-specific and 506 Stage 3 (drought stress)-specific AS genes. Stage-dependent changes in AS genes assigned to ‘response to stimulus’ may participate in plant tolerance to drought stress. Analysis of differential isoform expression of selected genes suggested that an AS event in the ubiquitination pathway may be required to control plant responses to drought stress. Taken together, these findings suggest that genes with specific-AS patterns may serve as potential genetic resources for future improvement of plant adaptation to drought stress.

Plasma lighting systems have been engineered to simulate sunlight. The objective of this study was to determine the effects of plasma lighting on tomato plant growth, photosynthetic characteristics, flowering rate, and physiological disorders. Tomato plants were grown in growth chambers at air temperatures of 25/23 °C (light/dark period), in a 16 h day−1 light period provided by four different light sources: 1 kW and 700 W sulfur plasma lights (1 SPL and 0.7 SPL), 1 kW indium bromide plasma light, and 700 W high pressure sodium lamp (0.7 HPS) as a control. The total dry weight and leaf area at 0.7 SPL were approximately 1.2 and 1.3 times greater, respectively, than that of 0.7 HPS at the 62 days after sowing (DAS). The maximum light assimilation rate was observed at 1 SPL at the 73 DAS. In addition, the light compensation and saturation points of the plants treated with plasma lighting were 98.5% higher compared with HPS. Those differences appeared to be related to more efficient light interception, provided by the SPL spectrum. The percentage of flowering at 0.7 SPL was 30.5%, which was higher than that at 0.7 HPS; however, there were some instances of severe blossom end rot. Results indicate that plasma lighting promotes tomato growth, flowering, and photosynthesis. Therefore, a plasma lighting system may be a valuable supplemental light source in a greenhouse or plant factory.

Horticultural crop production and changes in physiological aspects during the growing season may be affected by climate change factors (CC), which include increased temperature and the associated doubling or tripling of atmospheric CO2 concentrations. However, the potential effects are complex and many parameters might impact on the observed effects. To evaluate the effects of CC, the growth, yield, fruit characteristics, photosynthetic traits, and morphological characteristics of hot peppers were investigated. The hot peppers were grown under two CC scenarios, with the Representative Concentration Pathway (RCP) of 4.5 (Temp.; +3.4°C, CO2 conc.; 540 μmol/mol, Precipitation +17.3%) and RCP 8.5 (Temp.; +6.0°C and CO2 conc.; 940 μmol/mol, Precipitation +20.3%), respectively, using extreme weather simulators. This was compared with existing weather conditions occurring in Jeonju, South Korea in terms of air temperature, relative humidity, radiation, and precipitation. Overall, the plant height showed the highest under moderate CC conditions (RCP 4.5) among all the treatments tested. The number of leaves in the RCP 8.5 condition showed 7,739/plants, which was 2.2 times higher than that of the control. In addition, fruit shape was shortened and percentage dry matter was also the highest. The yield of hot pepper in the CC RCP 4.5 and 8.5 conditions were decreased by 21.5% and 89.2% when compared with that of the control, respectively. The days to harvest in the condition of CC scenarios were shortened from 5 to 13 compared with that of control, predominantly due to the increased air temperature. The results indicated that the severe RCP CC scenarios made reduction in the yields and negative affection on the fruit qualities. Overall, hot pepper was tolerant of mild CC scenarios of temperature × CO2 but was significantly affected by more extreme CC interacting parameter concentrations (or similar).
