| 摘 要： | 对采自7个五针松疱锈病典型发病区的10个茶藨子种源样本的叶表皮解剖结构研究表明:茶藨子植物对疱锈菌孢子不易感染组与易感染组之间在叶表皮结构上存在显著差异,其中主要是表皮厚度和角质膜厚度,不易感染组的叶表皮结构呈现显著增厚,表明角质膜厚度和表皮厚度与其抵抗疱锈菌感染有显著的相关性.以表皮结构各项指标聚类分析,不易感染组和易感染组明显聚为两类.

| Abstract: | The leaf anatomical structure of 10 provenances of Ribes sp.sampled from 7 typical incidence sites of Pinus parviflora blister rust disease was studied.It was showed that there was a significant difference on the structure of the leaf epidermis between the samples of susceptible provenances and the resistant ones.The major difference existed on the thickness of the cuticle and the epidermis.The leaf epidermis and the cuticle of the resistant provenance samples were both evidently thicker than those of the susceptible provenance samples.The results suggested that there be significant correlation between the resistance to blister rust disease caused by Cronartium ribicola and the thickness of leaf epidermis of Ribes sp.. |
