1、論文發(fā)表專家一芳香植物論文電導(dǎo)率測(cè)植物耐熱性論文：利用電導(dǎo)率法測(cè)定六種芳香植物的耐熱性摘要：運(yùn)用電導(dǎo)率法對(duì)香蜂草(melissaofficinalisl.)、蘋果鼠尾草(salviaofficinalisl.)、丁香羅勒(ocimumbasilicuml.)、闊葉薰衣草(lavandulaspical.)、匍匐迷迭香(rosmarinusofficinalisl.)、香露兜(pandanusamaryllifoliusroxb.）等6種芳香植物進(jìn)行了耐熱性測(cè)定。結(jié)果顯示，葉片在梯度高溫處理后，溫度與細(xì)胞傷害率之間呈現(xiàn)“s”形曲線關(guān)系。通過(guò)顯著性檢驗(yàn)，結(jié)合logistic方程拐點(diǎn)確定半致死溫度，

2、測(cè)得6種芳香植物的高溫半致死溫度分別為香蜂草57.00C、蘋果鼠尾草58.55C、丁香羅勒59.80C、闊葉薰衣草59.55C、匍匐迷迭香59.19C、香露兜65.25C。關(guān)鍵詞：芳香植物；高溫；logistic方程；半致死溫度。conducmeasurementofthermalresistanceofsixaromaticplantswithelectrical論文發(fā)表專家一tivitymethodgongping,wangjian(collegeofhorticultureandlandscapearchitecture,hainanuniversity/keylaboratroyofp
