After the yellowing seedlings of Hami malon were treated with spore suspension and the elictors from culture fitrate (E1) and mycelial wall(Ew) of Colletotrichum lagenarium
the contents of soluble carbohydrates (e
g
socrose
fructose and starch) and activities of enzymes ralative to the former (e. g. invertase
amylase) had different changes. Besides
chlorogenic acid accumulated apparently after inducement. The induced effects of spore suspension were better than those of the E1 and Ew.
