在浙江,枳砧员地早、槾桔、椪柑等树黄化情况严重,而这些枳砧黄化树的嫁接部,即砧穗接合处均出现黄褐色的“折痕”。过去,一般都认为枳砧柑桔黄化为生理性不亲和引起,作者(1987、1988)曾初步报道枳砧黄化树嫁接部的“折痕”与柑桔碎叶病毒有关。为进一步明确这种关系,作者进一步作了实验,本文即报道其结果。
In Zhejiang, Citrus aurantium staff early, orange, citrus and other tree yellowing serious, and these branches of the yellow tree of Hovenia dulcis, that the anvil spike joints are yellow-brown “creases.” In the past, it was generally considered that the yellow orange leaves of the lotus root were caused by physiological incompatibility. The authors (1987, 1988) initially reported that the “creases” of the branches of the yellow tree of the lotus tree were related to the citrus leaf fragment virus. To further clarify this relationship, the author made further experiments, this article is to report the results.
