摘要: 摘 要:以我国银杏主产区14个银杏栽培品种为材料,利用生理生化测定及SPSS统计分析对其耐热性进行研究。结果表明:持续7 d 45 ℃的高温胁迫能够有效区分不同银杏品种耐热性;生理生化测定结果的系统聚类与主成分分析能够对不同银杏栽培品种的耐热性进行有效评价。苏农佛手、郯城300和新村16号为热敏感型,耐热型较差,洞庭皇1号、郯城马铃2号和大龙眼为耐热型,耐热性较强。银杏栽培品种耐热性与核形的相关性不大。

Abstract: Abstract: Heat tolerance of 14 Ginkgo cultivars from the main planting section in China was investigated using physiological and biochemical measurements as well as the statistical analyses with spss softwave. Results indicated that heat tolerance of different Ginkgo cultivars could be distinguished effectively under a heat stress of 45 ℃for one week and could be effectively evaluated using a main component analysis and a cluster analysis from a data of the physiological and biochemical measurements. Cultivars of Su-nong、Tancheng300 and Xincun16 had the worst heat tolerance, while cultivars of Dong-tinghuang1、Tancheng2 and Da-longyan had the best heat tolerance. Heat tolerance of Ginkgo cultivars had little correlation with Ginkgo nucleus types.
