Abstract

Saurauia Willd. is a genus of perennial plant or bush which usually found in highland forest or as rheophyte in rocky areas along the river bed. There are 12 species of this genus found in West Sumatera. The purpose of this research is to analyze the grouping of Saurauia species based on morphometric analysis and determine the pollination system based on pollen-ovule (P/O) ratio. The research has been conducted since September 2014 until December 2015 by using the self-collected specimen and Herbarium ANDA specimen. Morphometric analysis was applied to all 12 species which consist of 21 morphological characters and pollen–ovule (P/O) ratio was applied to 10 species. The results of this research are: generally the euclidian distance is ranged 7.35-14.73. The shortest one is S. cerea and S. laxa which d point is 7.35 and the longest one is S. cerea and Saurauia sp. which the d point is 14.73. Saurauia sp. is closely related with S. leprosa and S. bracteosa which are belonged to same sub cluster and having the same character which are glabrous leaf surface, acuminate apex and 5 similar sepals. Pollen-ovule (P/O) ratio determined the pollination system of Saurauia is xenogami.

Abstract

Research on the exploration and identification of phosphate solvent fungi has never been carried out in West Bali National Park (TNBB), therefore researchers aims to explore and identify microscopic fungi to be used as phosphate solvent fungi which later will be taken from each plant soil samples (Lantana camara) that the presence is very common in TNBB. The research was implemented in two stages. The first stage is exploration of soil fungi in the field (TNBB) and identification of fungal species and the second stage is the phosphate solvent fungus test on Pikovskaya media. The results of the identification of the fungi obtained as follow: Aspergillus niger, Aspergillus bertholletius, Aspergillus flavus, Aspergillus isolate 4, Aspergillus isolate 5, Penicillium citrinum, and Trichoderma amazonicum. From the entire types of fungi obtained, there are onlybfour fungi that have the potential as phosphate solvents, namely Aspergillus niger, Aspergillus flavus, Aspergillus bertholletius and Penicillium citrinum with the presence of clear zones on Pikovskaya media. Fungi that has the best potential in the process of phosphate dissolution is Aspergillus niger. Key words: Rhizosfer, Lantana camara, clear zone, phosphate solvent fungus
