摘要:
以“辽宁1号”等6个核桃品种为试材，对参试树进行低温日灼及腐烂病发生的方位、病级、发病率等统计分析，研究了核桃腐烂病的发生与低温日灼的关系。结果表明：核桃腐烂病主要发生在成龄结果树枝干南或西南方向，发病处均伴有低温日灼现象；核桃不同品种间抗逆性存在着较大差异，低温日灼发生率低的品种腐烂病发生率也较低，但发生率均与发病程度无必然联系；腐烂病病情与低温日灼伤情密切相关。
Abstract:
Six walnut cultivars such as ‘Liaoning No.1’ were selected as test materials，position，disease level and morbidity of low-temperature sunburn and rot disease were measured and analyzed.The results showed that walnut rot disease mainly occurred in the south or southwest of the branches of the mature fruit trees，and the incidence of canker was accompanied by sunburn.There were significant differences in the resistance among different walnut cultivars，and which had low incidence of sunburn also had low incidence of rot disease；but the incidence and level of disease were not necessarily linked；the injury of rot disease and low-temperature sunburn was closely related.
