通过对栗树当年生枝条中酚类化合物进行的气相色谱法等定性定量分析 ,发现酚类化合物含量与抗栗瘿蜂性状之间存在明显的相关关系。提出邻苯二酚的抗虫临界值为 0 33mg/g (干重 ) ,原花色甙的抗虫临界值为 3 0mg/g (干重 ) ,据此认为 ,土 1 3号、丹泽、伊吹和中日 1号可评价为对栗瘿蜂有免疫或高度抗性的栗树品种。此外还对抗虫临界值在栗树抗虫筛选和无性系早期鉴定方面的应用进行了讨论。 Through the qualitative and quantitative analysis of phenolic compounds in the annual branches of chestnut tree, it was found that there was a significant correlation between the content of phenolic compounds and the traits of chestnut beetle. Proposed catechol anti-insect critical value of 0 33mg / g (dry weight), the original anti-insect anthocyanin critical value of 30mg / g (dry weight), which that soil 13, Danze, Yi blowing and China and Japan 1 can be evaluated as chestnut bee had immunity or highly resistant chestnut varieties. In addition, the application of the critical value of insect resistance in chestnut insect resistance screening and early identification of clones was also discussed.
