肉桂枝枯病病原研究

STUDIES ON THE PATHOGEN OF BRANCH-ROT OCCURRED ON CHINESE CASSIA TREE

肉桂枝枯与可可毛色二孢(Lasiodiplodia theobromae)及肉桂泡盾盲蝽(Pseudodoniellachinensis)有关.后者吸食肉桂枝条的汁液,造成大量微小伤口,并携带该菌,是有效昆虫传媒,使肉桂枝条容易被该茵侵染,造成皮层坏死,引发极严重的枝枯病.

The branch-rot occurred on Chinese cassia tree is associated with a insectnamed Pseudodoniella chinensis Zheng and a fungus named lasiodiplodia theobromae(Pat. ) Griff. &. Maubl. The fungus infects the bark through wounds and causes cankerson the branches of cassia trees. The insect sucks the juice in the green branches, createsa large number of tiny wounds on the cassia trees and it is the carrier of the fungus so itmakes the fungus infect the trees easily and results in serious branch-rot.
