- 摘要:
- 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℃5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(LT50)-24.8℃，无核白鸡心嫁接苗抗冻性最弱(LT50) -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。
- Abstract:
- Treat the roots at the temperatures of -20℃,-25℃,-30℃,-35℃,-40℃ before test the electrolytic leakage. The semi-lethal temperatures (LT50) of four grafted grape cultivars root was conduced by using conductance method with Logistic. The experiment results showed that the semi-lethaltemperatures between -21.4℃ and -24.8℃.Jingya’s cold-resistant ability is best,and the Wuhebaijixin’s is worst.The order of cold-resistant ability is 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.The experiment results will be used when study the mechanisms of cold-resistant ability production.
