不同苹果品种（系）枝干轮纹病抗性鉴定及机制研究
Resistance Identification and Mechanism Study of Different Apple Varieties(Lines)to Botryosphaeria dothidea
摘要
Abstract
The burl diameter and disease incidence of lenticel were investigated after inoculation.The resistances of 51 apple materials to Botryosphaeria dothidea were identified.Jiguan,94 -9 -21,94 -7 -13, 94 -1 -3,94 -1 -42,94 -2 -20,94 -1 -13,94 -1 -15 and 95 -76 were screened as resistant materials. The lenticel structures and phenolic compound contents of 1 -year -old branches were compared among differ-ent cultivars(strains).The lenticel of resistant cultivars (strains)possed closing layer with more layers of cor-tical cells arranged densely.The content of chlorogenic acid in cortex of resistant cultivars (strains)was high-er than that of susceptible cultivars (strains).It seemed to be that the lenticel structure and chlorogenic acid content in the cortex might be correlated with the resistance of apple branches to Botryosphaeria dothidea.关键词
