摘要
1986年至1987年,多次对从江苏南京和句客不同地块内采集的草莓矮缩病株地上部(大鸡冠300株,宝交早生200株和美国6号30株)进行分离,都获得同一种滑刃属线虫。经研究,这种线虫与Christie(1942)原始报道的Apbelenchoides besseyi以及从水稻干尖线虫病病种上分到的A.besseyi在形态特征上完全相同或相似,因此将其鉴定为Apbelcnchoides besseyi Cbristie,1942。对分自江苏草莓和稻种的A.bessezi进行人工培养,然后交互接种草莓和水稻,在两种线虫处理中都出现了典型的草莓矮缩和水稻干尖症状,并从有关病株内分离到与接种相同的线虫,由此证实江苏草莓夏矮病的发生。
From 1986 to 1987,a same species of Aphelenchoides was isolated from the buds and leaflets of stunted strawberry plants(Fragaria ananassa)collected from individual fields in Nanjing and Jurong,Jiangsu province.On the ground of its conformity with the original descripsion of phelencho ides besseyi by Christie(1942)and its remarkble resemblence to Aphele nchoides besseyi isolatedfrom diseased rice seeds from Jurong,it was iden tified as Aphelenchoides bess-eyi Christie,1942.Artificial inoculation proved that A.besseyi from both strawberry and ri-ce in Jiangsu can induce typical“dwarf”on strawberry(mainly severely stun-ted plants with crinkled leaflets)and“white tip”on rice.This further confirm-s that the concerned dwarf disease of strawberry in Jiangsu is the“summer dwarf”caused by Aphelenchoides besseyi.
