摘要
2018年8月在江苏省常州市金坛区薄壳山核桃种植园资源圃,调查了11个薄壳山核桃主要推广栽培品种果实黑斑病发病情况。结果显示,不同薄壳山核桃品种的发病率和病情指数存在着显著性差异,发病率和病情指数的大小依次为无性系3>马汉>无性系4>无性系2>无性系5>绍兴>坎扎>金华>无性系6>波尼>无性系1;薄壳山核桃的黑斑病发生与果实形状有一定的相关性,发病率和发病指数与果实长度成正相关,与果实宽度成一定负相关。
Black spot disease occurrence of total 11 pecan varieties was investigated in plantation of Jintan,Changzhou in August 2018.The results indicated that there were significant differences in the incidence and index,with such an order as Clone 3 >Mahan >Clone 4 >Clone 2 >Clone 5 >Shaoxing >Kanza >Jinhua >Clone 6 >Pawnee >Clone 1.At the same time,it was found that there was a certain correlation between the occurrence of black spot disease and fruit shape,which was,in detail,the incidence and disease index were positively correlated with fruit length and negatively correlated with fruit width.
