埋土防寒和越冬冻害是北方葡萄栽培的重要问题。为加快抗寒育种进程及测定品种的抗寒性,采用电导法探讨品种的抗寒性及抗寒杂种实生苗露地越冬的生理指标,作为预测方法。为此,首先对用电导仪测定葡萄抗寒性的方法进行了初步探索,以便制定适宜的取样标准,采用较适合的处理方法和测定方法。 Buried cold and winter frost damage is an important issue of northern grape cultivation. In order to speed up the process of cold breeding and to measure the cold resistance of varieties, the cold resistance of varieties and the physiological indexes of overwintering cold-resistant hybrid seedlings were studied by using the conductance method as the prediction method. To this end, the method of measuring the cold resistance of grapes by conductivity meter was first explored in order to develop appropriate sampling standards, the use of more appropriate treatment methods and determination methods.
