芳香植物论文电导率测植物耐热性论文：利用电导率法测定六种芳香植物的耐热性

1、论文发表专家一芳香植物论文电导率测植物耐热性论文：利用电导率法测定六种芳香植物的耐热性摘要：运用电导率法对香蜂草(melissaofficinalisl.)、苹果鼠尾草(salviaofficinalisl.)、丁香罗勒(ocimumbasilicuml.)、阔叶薰衣草(lavandulaspical.)、匍匐迷迭香(rosmarinusofficinalisl.)、香露兜(pandanusamaryllifoliusroxb.）等6种芳香植物进行了耐热性测定。结果显示，叶片在梯度高温处理后，温度与细胞伤害率之间呈现“s”形曲线关系。通过显著性检验，结合logistic方程拐点确定半致死温度，

2、测得6种芳香植物的高温半致死温度分别为香蜂草57.00C、苹果鼠尾草58.55C、丁香罗勒59.80C、阔叶薰衣草59.55C、匍匐迷迭香59.19C、香露兜65.25C。关键词：芳香植物；高温；logistic方程；半致死温度。conducmeasurementofthermalresistanceofsixaromaticplantswithelectrical论文发表专家一tivitymethodgongping,wangjian(collegeofhorticultureandlandscapearchitecture,hainanuniversity/keylaboratroyofp
