Mycorrlizal Association of Glomus clarum with Watermelon and Soybean

Abstract

The growth of soybean was enhanced by the inoculation with Glomus clarum at the initial inoculum of 50 chlamydospores per plant. The invading hyphae of G. clarum produced appresoria on the root surface of watermelon and soybean at 5 and 9 days after inoculation, respectively.內生菌根菌(Glomus clarum)之接種源係採百喜草盆栽培養之土，以篩網傾注法來分離厚膜孢子。內生菌根產生有益效應之最初接種量(initial inoculum density)之決定，是於盆栽大豆進行孢子接種試驗，大豆之最初接種量以每棵50個孢子即能促進植株生長，而每棵接受200個孢子更顯著地的增加地上部及地下部之生長。
