Regulation of non-structural carbohydrates (NSCs) are important for plants in response to submergence. In this study, the difference in non-structural carbohydrates in relation with shoot elongation between Sub1A and non-Sub1A rice genotypes was investigated. Two rice genotypes, namely Inpari30 (Sub1A genotype) and IR72442 (non-Sub1A genotype), were submerged completely for 6 days and re-aerated by lowering water level up to stem base for 6 days of post submergence. In addition, non-submerged plants (control) was treated with water level up to stem base during the experiment. Photosynthesis rate decreased in both submerged Inpari30 and IR72442 genotypes 71% and 96% lower than their control, respectively. Submerged IR72442 declined Fv/Fm 15.6% lowest than its control and both control and submerged Inpari30. Investigation of the distribution of starch and soluble sugar content in plant organs suggested that shoot elongation of non-Sub1A genotype led to starch and sugar consumption that distributed faster to the new developed organ during submergence. In contrast, Sub1A genotype of Inpari30, which did not exhibit shoot elongation and showed slower NSCs distribution during submergence, performed better on post submergence by maintaining NSCs and distributing to the new developed organ faster than IR72442. These results suggest that Sub1A genotype managed elongation and NSCs during submergence more efficiently than non-Sub1A genotype.

Submergence is an environmental challenge for crop cultivation which causes physiological perturbation and yield loss. Tolerant genotypes are characterized by the ability to maintain physiological processes, especially photosynthesis, minimizing the negative effects of flooding stress. This experiment was aimed to examine the photosynthetic ability during submergence and a recovery period in rice variety of Inpari30 (carrying gene Sub1) compared to IR72442 (an elongation type) under control and submergence treatment. A randomized complete block design was employed in this experiment with three replications. The first factor was the environmental condition consisting of control and submergence. The second factor was rice varieties consisting of Inpari30 and IR72442. Fourteen-day-old seedlings were submerged under 35 cm of water depth for 6 days and re-aerated by lowering the water level up to the stem base for 6 days of recovery. Measurement of plant height, SPAD, Fv/Fm and photosynthetic rate were taken continuously from the same plant sample following the experimental stage. The results showed that shoot length increased significantly more in IR72442 than in the quiescent Inpari30. The noticeable decline was observed in the photosynthetic rate of both varieties during submergence with chlorophyll content and chlorophyll fluorescence (Fv/Fm) decreased more severely in IR72442 than in Inpari30. After flooding, Inpari30 adapted quickly to the aerobic environment, as shown by a recovery in Fv/Fm and accumulated dry weight more quickly than IR72442. We concluded that the Sub1 genotype of Inpari30 confers the ability to maintain maximum quantum yield of PSII under conditions of limiting gas exchange for photosynthesis for adapting post submergence

Flooding imposes a severe selection pressure on plants principally because excess water in their surroundings can deprive them of certain basic needs, notably of oxygen and of carbon dioxide and light for photosynthesis. It is one of the major abiotic influences on species' distribution and agricultural productivity world-wide. A cultivated species, O. glaberrima is origin from Africa that spread to floodplains area along river. Work to develop more tolerant crops or manage flood-prone environments more effectively is also included. Here, recent progress in elucidating the mechanisms determining tolerance versus intolerance to anaerobic stress caused by flooding in higher plants is discussed. This work integrates various specialized approaches ranging from morphology to physiology, and demonstrates how plant biology can be harnessed to improve stress tolerance in an important crop species. Materials and Methods: The research is conducted in various place of fields. As materials of rice and sugarcane, and chilli pepper are used in the experiments. Results and Discussion: We emphasize that Sub1A is not appropriate when selecting and breeding rice cultivars of O. glaberrima for resilience to longer-term submergence. Under these circumstances, a vigorous ethylene-mediated underwater elongation response by leaves is needed to return leaves to air-contact and full photosynthetic activity. Root aerenchyma is formed in waterlogged condition to on the genotype of sugarcane and oxygen in the air is supplied to the root system thorough aerenchyma. The supplied oxygen is used for root system respiration.

Flood is one of the major environmental constraints that may harm plant productivity which requires specific mechanism to cope with stress. Flood prone area where rice is major crop to be cultivated, transplanting method on cultivation system cost high labor with consequence on low seedling survival. Direct seeding may offer solution for this condition with additional improvement needed on seed tolerant to germinate on anaerobic environment. An experiment was conducted to evaluate 23 rice varieties of tolerance to flooding stress on germination stage under 5 cm water depth. The experiment design was Nested – Randomized Complete Block Design with two factor and three replications. Result showed that rice germination under anaerobic condition was varied with Lambur has highest survival rates among others. Tolerance level was characterized from higher survival ability followed by high biomass accumulation and length of the shoot and root.Keywords: anaerobic germination, direct seeding

Rice (Oryza sativa L.) is largely cultivated in lowland area that vulnerable to flood occurrence. Root supposed to play an important role on rice tolerance to submergence stress. An experiment which conducted from January to May 2014 in Cikarawang Field Laboratory, Darmaga, Bogor, West Java aimed to study the role of root distribution on rice submergence tolerant. The experiment used Split Plot design replicated three times, with the depth of submergence as main plot and rice variety as subplot. The main plot consisted of water depth of 5 cm (optimum), 50 cm, 60 cm and 80 cm from soil surface. The subplot consisted of four rice varieties, namely Ciherang, Inpari 30 (Ciherang Sub1), Indragiri and Margasari. Each plant was planted in a root box (30 cm x 40 cm x 5 cm) which put into container (67 cm x 47 cm x 42 cm) and placed into the pond with water depth as treatment. Submergence started when the plant was 39 DAS (Days After Seeding) for ten days. Observation conducted after the submergence stopped (49 DAS). Result showed that submergence retarded plant growth, root distribution and increase root damage for all rice varieties with the biggest effect on susceptible varieties.
