Endophytic bacteria live in plant tissues which utilized in plant protection against phytopathogens. This study aims to investigate the diversity of endophytic bacteria from the leaves of traditional medicinal plants that has anti-phytopathogens properties. Isolation of endophytic bacteria was done by spread plate method. The bacteria were characterised by Gram staining and the 16S rRNA gene analysis. Further screening of anti-phytopathogen activity used disc diffusion method for Ralstonia solanacearum, Xanthomonas campestris, Fusarium oxysporum, and Sclerotium rolfsii. All togethers, sixteen isolates of endophytic bacteria from the leaves of eight medicinal plants species were obtained. Fourteen isolates had an anti-phytopathogen (with eight isolates against R. solanacearum, seven isolates against X. campestris, nine isolates against F. oxysporum, and five isolates against S. rolfsii). From the 14 isolates identified, phylum Firmicutes were dominant (64.3%), followed by Proteobacteria (28.6%), and Actinobacteria (7.1%). Phylum Firmicutes consists of Bacillus indicus (BJF1, TCF1, and MCF2), Bacillus pumilus (CAF4), Bacillus sp. (CAF1), Bacillus subtilis (AAF2, MCF1, CAF3, and MCF3); phylum Proteobacteria consists of Pantoea agglomerans (CAF2), Pantoea stewartii (AAF4), Pseudomonas oryzihabitans (AAF3), and Pseudomonas psychrotolerans (AAF1); and phylum Actinobacteria consists of Kocuria kristinae (CSF1).

Jernang (Daemonorops draco (Willd.) Blume) is a dioecious rattan species that produces resin on female individuals. The sex of jernang can only be identified from its inflorescences morphology. Sex survey was conducted in 5 populations ofÂ jernang, 3 populations of which in the Bukit Tigapuluh National Park (BTNP), 1 population in the secondary forest in Jambi province and 1 population in the area of rubber plantation in Jambi province. Chi-Squared test on the sex ratio ofÂ jernang showed that the ratio of the male to female in their natural habitat (Bengayoan and Tebo, 2 parts of the BTNP ecosystem and the Sepintun secondary forest) was distorted from the normal ratio of 1:1, while the cultivated jernang in Nunusan population (BTNPT) and Mandiangin were not significantly different from the normal sex ratio of 1:1. Female individuals from the cultivated population in the Mandiangin (planted in 1997) has an average number of stems per clump more on individual males (27.12) than females (26.92). The result of this study indicated that the D. draco has a good reproductive strategy and thus suitable for cultivation.

Natural cavities in polyculture plantations are important for the conservation of honeybees. This study was aimed to determine the diversity, nest sizes, and fluctuations in the use of sites for nesting by Apis cerana Fabr. in polyculture plantations in two altitudes in West Sumatra. A census method was used to obtain the data variables in 10 plantations (five locations for each altitute). Polyculture plantations used as the study sites were dominated by coconut in lowland areas and coffea in highland areas. The results showed that nesting sites of Apis cerana were found amongst 18 species of plants belonging to 15 families (12 species in lowlands and seven species in highlands). Most of the nests were placed on Cocos nucifera (coconut) treesin lowland sites, and on Erythria variegata (dadap) in highland sites. Nests were also found to be located mostly in the cavities of trees with diameter 21-60 cm. Nest entrances were located at 228.31 cm above ground surface (ags) in highland and at 116.04 cm agsin lowlands. The nest entrances in highlands measured 12.21 by 3.73 cm (height and width), and in the lowlands 14.93 by 7.36 cm. The percentage of tree cavities used for nesting was statically higher in lowland (40.73%) compared to high land (17.86%), but it fluctuated very slightly in both high or lowland areas during observation. The percentage of trees with nests decreased in December and January but increased in February, with the same patterns found in both high and lowlands. Our research suggests that higher tree diversity in polyculture plantations promotes increased use by honeybees for nesting. Thus, the more tree diversity in polyculture plantations the better it could conserve natural honey bees populations.

Penelitian tentang penyerbukan dan sistem reproduksi Ranunculus japonicus telah dilakukan di kebun botani Universitas Osaka City, Katano, Osaka, Japan. Hasil penelitian menunjukkan bahwa putik R. japonicus lebih dahulu masak daripada benang sarinya (protogyny). Pada tumbuhan ini terjadi ketidakcocokan silang sendiri (self-incompatible). Tumbuhan ini tidak mengalami penyerbukan sendiri (selfing) dan juga tidak membentuk biji tanpa pembuahan (agamosper my), tetapi melakukan penyerbukan silang (out-crossing) dan membutuhkan perantara (pollinator) untuk pembentukan bijinya.

The putative natural hybrid between Anaphalis longifolia and Anaphalis javanica from Talang Mountain in West Sumatra has been discovered. The aim of this research is to analyze the anatomical characteristics of the leaf and stem to clarify the status of this putative natural hybrid. The anatomical characteristics of leaves and stem were analyzed by making cross sections and paradermal sections using Johansen’s method. The results show seven characteristics of this putative natural hybrid (the stomata density, length, width, and length/width ratio; the number of cortical cell layers, the range of cortex length, and the range of cortex width) that were close to A. longifolia, one characteristic that was close to A. javanica (the structure of palisade), one characteristic that was intermediate (the structure of spongy layer), and one characteristic that was a combination of both of them (the trichome morphotype). All of the foregoing characteristics can be used to support the identification of a natural hybrid of A. longifolia and A. javanica.
