2009年郑州地区猕猴桃冻害调查与原因分析
Freeze injury investigation of kiwifruit in Zhengzhou area in 2009
摘要
Abstract
The frozen injury of kiwifruits including two years old grafted nursery stock, juvenile seedlings and adult trees was investigated in the Germplasm Repository of Zhengzhou Fruit Research Institute. The temperature in the field, the anatomical structure and eletrolytical leakage percentage of branches were observed as well. The results showed that the reasons for the frozen injury in kiwifruit trees in Zhengzhou in 2009 were the severe cold weather in mid-November of the year. It seemed that the tolerance to freeze of A. chinensis kiwifruit was stronger than that orA. chinensis var. deliciosa kiwifruit. The order of the percentage of the electrolytical leakage was A. chinensis var. deliciosa, A. chinensis and A. arguta. It was suggested that the thickness of collenchyma, the ratio of collenchyma thickness to cane diameter, and the ratio of xylem thickness to cane diameter could be used as morphological index to evaluate the cold resistance of kiwifruit trees.关键词
