【摘要】 采用自然鉴定法和电导法对山樱桃、大青叶、吉塞拉5号嫁接的甜樱桃品种早大果的抗寒性进行了鉴定、比较。结果表明,吉塞拉5号砧的早大果冻害率最低,抗寒性最强。3个处理在不同低温下的电解质渗出率存在显著差异,吉塞拉5号砧的早大果与其他两个处理间还存在极显著差异。3个处理的抗寒性强弱顺序为:吉塞拉5号砧>山樱桃砧>大青叶砧。更多还原

【Abstract】 Cold resistance of sweet cherry Zaodaguo grafted with 3 stocks of wild cherry,Daqingye,Gisela No. 5 was identified and compared through two methods,natural identification and exudation of electrolyte method. The results show that the cultivar grafted with Gisela No. 5 has the lowest cold injury and the strongest cold-resistance. Exudation rate of the electrolyte for the 3 treatments under different low temperatures is significantly different:the cultivar grafted with Gisela No. 5 is also significantly different from the other two treatments. The order of cold resistance of the three stocks is Gisela No. 5>wild cherry>Daqingye...更多还原
