不同丝瓜品种早熟性及抗寒性的比较

以"江蔬一号"、"六叶生"、‘长沙肉丝瓜’‘杭州肉丝瓜’和"驻丝瓜1号"5个优良丝瓜品种为试材,对其早熟性和抗寒性进行测定,以期筛选出适宜北方温室生产的丝瓜品种。结果表明:"江蔬一号"的早熟性最好,"驻丝瓜1号"次之,但"驻丝瓜1号"早期产量最高,这2个品种的幼苗在低温胁迫过程中Pro、SOD和POD含量显著高于其它3个品种,MDA含量最低,抗寒性明显高于其它丝瓜品种,故"江蔬一号"和"驻丝瓜1号"可作为北方温室冬春季丝瓜栽培品种。

Comparing on Earliness and Cold Resistance of Different Towel Grourd Breeds

With’Jiangsu No.1’,’Liuyesheng’,’Changsha flesh grourel’,’Hangzhou flesh grourell’ and ’Zhusiguarcl No.1’ as materials,the earliness and cold resistance of the five excellent precocious towel gourd varieties were determined.The results showed that the earliness of ’Jiangsu No.1’ was the best because the early flowering season and the early fruiting season of ’Jiangsu No.1’ were the earliest.Followed by ’Zhusi gourcl No.1’ and the early yield of ’Zhusi gourcl No.1’ was the highest.The cold resistance of ’Jiangsu No.1’ and ’Zhusi gourcl No.1’ were stronger than the other towel gourd varieties because the Pro,SOD and POD content of ’Jiangsu No.1’ and ’Zhusi gourcl No.1’ were the highest and the MDA of ’Jiangsu No.1’ and ’Zhusi gourcl No.1’ were the lowest,so the ’Jiangsu No.1’ and ’Zhusi gourcl No.1’ can be used as greenhouse cultivation of varieties in winter and spring and provided theoretical basis for parental set of chromosome of breed special varieties of greenhouse in northern region.
