Characterization of endophyt fungi in bali grapevine (vitis vinifera l. var alphonso lavalle) in Buleleng, Bali

Abstract

Abstract Bali grapevine is a local fruit cultived in banjar district, but the productivity and quality of the grapes has decreased each year because of disease, consequently farmers have to use chemical pesticides to deal with disease attacks that actually cause adverse effects. So a solution is needed to solve this problem by using endophytic fungi as a natural biological agent. This research was aimed to determine the (1) total number of fungi colonies and (2) genus of endophytic fungi on Bali grapevine in a vineyard at Banjar village. The observation using descriptive research. Based on the observation that had been done, the result of this research were(1) There was a variation of total number of endophytic fungi colonies in the roots part 6.5 x 104 CFU/gram, in the stems 2.9 x 104 CFU/gram, and in the leaves 2.6 x 104 CFU/gram, so it was known that the largest total number of endophytic fungi colonies found in the root. (2) Genus of endophytic fungi found on the root, stem, and leaf, were Trichoderma, Fusarium, Scytalidium, Aspergillus, Scedosporium, Alternaria, dan Microsphaeropsis.
