Effect of the indigenous trichoderma application on germination of black glutinous rice seed

Abstract

Trichoderma is one of the rhizosphere microorganisms that are able to play as plant growth promoting fungus (PGPF) because it can produce IAA hormone. The ability of Trichoderma as PGPF has been extensively studied, but the indigenous Trichoderma effect derived from the rhizosphere of rice crops on local rice variety of west Sumatera has not been widely studied. This study aims to determine the effect of Trichoderma application on black glutinous rice seed germination. The experiment is done by soaking the local black sticky rice seeds with Trichoderma spore suspension with 107 spore / mL density for 24 hours. The germination rate of each isolate observed at seven days after sowing. The results showed that the type of isolate affected the rate of germination of rice seeds. The highest germination was found in isolates from the rhizosphere of rice varieties cisokan balang (94%) and the lowest was in the control (74%).
