This species had been invaded many forests in Indonesia. This species would invade more area due to deforestation. The objectives of this study were to know the mapping and distribution pattern of B. pentamera; to know the effects of distance from road and light intensity to distribution of B. pentamera. This study was conducted from March to August 2020 in Conservation Area of PT. TKA Solok Selatan using belt transect method by plotting 20x50 m2. Data was analyzed using Morishita Index and Linear Regression. Distribution pattern of B. pentamera in PT. TKA was clumped, showed by 1.17 of Morishita index. Seedlings and saplings of B. pentamera were dominant at the edge of conservation forest while trees were distributed from the middle to inside of the forest. Distance from road gave positively effects and significantly towards distribution of B. pentamera showing result 0.702 of R2 and 0.007 of p-Value. Light intensity did not give effects significantly towards distribution of B. pentamera showing result 0.0806 of R2 and 0.427 of p-Value.","PeriodicalId":33376,"journal":{"name":"Jurnal Biologi Universitas Andalas","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48514831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T. chantrieri has a unique inflorescence morphology like that of a bat. The people of Southeast China and Thailand have used by T. chantrieri rhizome as traditional medicine because the methanol extract contains secondary metabolites such as diarylheptanoids, pseudofurostan, withanolide, taccalonolide, and saponins. To maintain its sustainability, it is necessary to propagate T. chantrieri by using in vitro culture techniques such as callus culture. The purpose of this study was to determine the response of T. chantrieri leaf callus formation and to determine the optimal concentration with various concentrations of 2,4-D and BAP in vitro. This study used a completely randomized design consisting of control treatments, 1 and 2 mg L-1 2,4-D and concentrations of 0.5; 1.0; 1.5; 2.0 2,4-D combined with 3 mg L-1 BAP. The observations were made for 60 days after planting. The results showed that the concentration of 1.5 mg L-1 2,4-D + 3 mg L-1 BAP affected the percentage of live explants and the percentage of callus formation by 100% respectively, and the time of callus appeared 18.75 days after planting.","PeriodicalId":33376,"journal":{"name":"Jurnal Biologi Universitas Andalas","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69196834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey method was used in this study. The study site was determined by purposive sampling based on environmental condition which was divided into four stations. Macrozoobenthos samples were taken using a surber net (30 x 30 cm2). The physical and chemical factors of water condition were measured during sampling time. The results showed that 23 genera of macrozoobenthic communities were found in the Batang Kandis river which were consisted of two classes i.e., Hirudinea (1 order, 1 family, 1 genus) and Insect (7 orders, 14 families, 22 genera). These macrozoobenthic communities had an average density ranges from 220.00 - 706.67 ind. m-2 with the highest density was found at Station II and the lowest one at Station IV. Variation in the predominant genus was found at every station: Orthocladius and Elophila (station I); Polypedilum, Orthocladius, Elophila, and Hydropsyche (station II); Polypedylum, Macropelopia, and Caenis (station III); and Polypedylum, Orthocladius, and Caenis (station IV). The water quality of Batang Kandis river was classified into not polluted (station I, II and III) to slightly polluted (station IV) based on the BMWP-ASPT indexes.

H. tiliaceus need a better nutrient to grow on coastal land that is still constrained by the high level of salinity. By this, a special treatment is needed to support its growth. One of them is the application of mycorrhizal inoculants. Mycorrhizae is known as one of the fungi that can help plants tolerate salinity. The aims of the research were to determine the effect of AMF inoculants and determine the best doses of AMF to the seedling growth. The research used completely randomized design with 5 treatments and 5 replications. The treatments were (A) without AMF (control), (B) inoculation AMF 10 g/plant, (C) inoculation AMF 15 g/plant, (D) inoculation AMF 20 g/plant and (E) inoculation AMF 25 g/plant. The result showed that AMF can infect the roots of hibiscus seedlings with an infection degree of 18-34%.
