Abstract
Seed of sorghum cv. M 35-1 were soaked in sol. of toxic metabolites prepared from still or shaken cultures of H. longirostratum. An increase in exposure time progressively inhibited germination. Preparation from shaken cultures were more toxic than from still cultures and reduced germination by 30%. Root growth was reduced more than shoot growth by the toxin. It also induced considerable loss of electrolytes from the treated seeds, and still culture preparations were more active. Leakage of electrolytes was higher on toxin-treated leaves than in the untreated control; leakage increased with increase in time of exposure to the toxin.ADDITIONAL ABSTRACT:An increase in the period of exposure to toxic metabolites of an isolate of H. longirostratum [Drechslera longirostrata] from Borassus flabellifer progressively inhibited germination of seeds of the susceptible sorghum var. M 35-1. Preparations from submerged cultures were more toxic and reduced germination by 30%. Root growth was more sensitive than shoot growth. The toxin also induced considerable loss of electrolytes from treated seeds and leaves, the effect increasing with exposure
