以葡萄嫁接苗根系为试材,测定半致死温度,以探讨不同品种接穗对根系抗寒性的影响.设定-20、-25、-30、-35和-40℃五个处理温度,通过测定电导值,配合Logistic方程测定了4个鲜食葡萄品种嫁接苗根系低温半致死温度.结果表明:4个葡萄品种根系LT50在-21.4～-24.8℃;京亚嫁接苗抗冻性最强(LT_(50))-24.8℃,无核白鸡心嫁接苗抗冻性最弱(LT_(50)) -21.4℃.抗寒性由强到弱的顺序为京亚嫁接苗、贝达苗、无核白鸡心嫁接苗、红地球嫁接苗.
以葡萄嫁接苗根繫為試材,測定半緻死溫度,以探討不同品種接穗對根繫抗寒性的影響.設定-20、-25、-30、-35和-40℃五箇處理溫度,通過測定電導值,配閤Logistic方程測定瞭4箇鮮食葡萄品種嫁接苗根繫低溫半緻死溫度.結果錶明:4箇葡萄品種根繫LT50在-21.4～-24.8℃;京亞嫁接苗抗凍性最彊(LT_(50))-24.8℃,無覈白鷄心嫁接苗抗凍性最弱(LT_(50)) -21.4℃.抗寒性由彊到弱的順序為京亞嫁接苗、貝達苗、無覈白鷄心嫁接苗、紅地毬嫁接苗.
이포도가접묘근계위시재,측정반치사온도,이탐토불동품충접수대근계항한성적영향.설정-20、-25、-30、-35화-40℃오개처리온도,통과측정전도치,배합Logistic방정측정료4개선식포도품충가접묘근계저온반치사온도.결과표명:4개포도품충근계LT50재-21.4～-24.8℃;경아가접묘항동성최강(LT_(50))-24.8℃,무핵백계심가접묘항동성최약(LT_(50)) -21.4℃.항한성유강도약적순서위경아가접묘、패체묘、무핵백계심가접묘、홍지구가접묘.
Treat the roots at the temperatures of -20℃,-25℃,-30℃,-35℃,-40℃ before test the electrolytic leakage. The semi-lethal temperatures (LT_(50)) of four grafted grape cultivars root was conduced by using conductance method with Logistic. The experiment results showed that the semi-lethal temperatures between -21.4℃ and -24.8℃.Jingya's cold-resistant ability was best,and the Wuhebaijixin's was worst.The order of cold-resistant ability was Jingya,Beida,Wuhebaijixin,and Hongdiqiu.The experiment use the grafted grape roots in order to study on the influence of aerial part to the root cold-resistant ability.
