The one of identification system using morphophysiological analyses for breeding program Mahogany is needed. Mahogany (Swietenia macrophylla) is a tree species which is easy to cultivate as it is able to thrive in a great variety of habitats and soil types. Here, we present a study on the relationship between morphological and physiological parameters on S. macrophylla. The study was carried out in a seed orchard of Mahogany in genetic resource area of 2^ndForest Seed/Seedling Office, Gowa district, South Sulawesi, Indonesia, in October 2017 up to March 2018. Morphological and physiological analyses were performed on 31 S. macrophylla leaf samples. The morphological parameters consisted of leaf color, leaf shape, leaf tip, leaf base, leaf margin, upper leaf surface texture, leaf venation, and tree diameter. Meanwhile, the physiological ones were chlorophyll content, leaf area, and water content. Leaf samples were divided into three colors, two leaf shapes, and three leaf base shapes. They also had tapered leaf tip, pinnate venation, and glabrous leaf surface. The chlorophyll content and leaf area had a very low coefficient correlation, whereas leaf area and water content showed very high coefficient correlation. The relation between morphology and physiology could be determined by the correspondence between chlorophyll content and leaf color. The higher chlorophyll content, the greener the observed leaf.

Diosphyros celebica Bakh., also known as Sulawesi ebony, is an endemic to central and northern Sulawesi. Information about pollen dispersal patterns of D. celebica have not been previously investigated. This study was aimed to determine pollination type, percentage of selfing and outcrossing, as well as distance of pollen dispersal of D. celebica. This study was conducted at experimental forest of Universitas Hasanuddin, Maros District, South Sulawesi Province, Indonesia. One hundred and sixty six individuals of D. celebica consisted of adult trees and seedlings were analyzed in this study. Ninety four adult trees were selected to become parent trees. The trees were mapped with GPS coordinates . All samples were genotyped using four SSR markers loci. Parental analysis and determination of pollen dispersal patterns were carried out using Cervus 3.0.3. Results indicated that the evaluated markers were effective for assigning candidate of male parents to all evaluated seedlings. Donated pollens could come from male parents in any directions relative to female parent positions. Pollen dispersal pattern showed outcrossing pollination among different male parents (pollen donated trees). The results indicated that seeds were produced predominatly by outcrossing. Pollen dispersal reached up to 166 m. Pollen related processes were linked through female parents, pollinators availability and ecological environment. Simultaneous use of progeny genotyping, spatially explicit analysis of environmental variables and outcomes of plant–animal interactions, were the key elements for an expanded approach to gene flow analysis considering dispersal via pollen and seeds. Research on pollen dispersal of D. celebica should be carried out in other forest types, such as mixed forest and highland forest.

Rhizosphere is a part of the soil that is in the roots of plants in which there are many soil microorganisms. One of the microorganisms found in the rhizosphere is fungi. Rhizosphere fungus plays an important role in increasing plant growth by various mechanisms that are carried out such as increasing nutrient absorption, as a bilogical control of pathogenic attacks and can produce growth hormones for plants. This study aims to identify and get the information of the diversity of rhizosphere fungi from mahogany stands in two provenances, and get information on IAA level production. The research methods include isolation of fungi and identification of rhizosphere fungi, as well as test of IAA production capability qualitatively and quantitatively. The results showed 17 rhizosphere fungus isolates were found under the mahogany stand in Takalar District those were included in the genus Rhizopus, Fusarium, Aspergillus, Penicillium and Gliocladium, whereas 11 Mahogany stands in the Maros Regency were included in the genus Trichoderma, Gliocladium, Rhizopus and Aspergillus. The whole genus is capable of producing IAA hormone, but the genus capable of producing the highest IAA is the Trichoderma genus.

Jabon Merah (Anthocephalus macrophyllus Roxb. Havil) is a fast growing local species and has bright economic and market prospects. However, the cultivation is unable to accelerate the productivity of this species. One of the breeding strategies to overcome this problem is to establish Seedling Seed Orchard of progeny test were later converted into seed orchard after one up to several selective thinning. This research was aimed to study the growth of Jabon merahs’ families from ten seed zonations in Sulawesi. It was conducted in a Randomized completely block design (RCBD) consisted of 108 families, four treeplots, and seven blocks with planting spacing of 4x3 meters. The measurement was performed at 24 month-old trees, i.e., tree height and diameter. Percentage of the living tree after two years based on progeny test was 69% with 6.1 m of mean height and 7.8 cm of mean diameter at chest height. Heritability of family for height and diameter at chest height were 0.2337 and 0.1873, respectively. Correlation between genetic and tree height and diameter traits was 0.9121.
