| 摘 要： | 采用4种方法测定了5种景天属地被植物叶片的抗寒性,对测定结果与品种抗寒性进行分析。结果表明:结合当地田间抗寒性观察,5种景天属植物中凹叶景天抗寒性最强,垂盆草、佛甲草抗寒性最弱,圆叶景天和胭脂红景天居中。对测定方法进行比较表明,初步测定几种景天属植物的抗寒性,可以采用电导率方法,该法既简便又反应灵敏,如若要精细比较抗寒性,可以采用电导率、含水量、可溶性蛋白质、可溶性糖4个指标综合测定。

| Abstract: | The cold tolerance of 5 Sedum spp.,including Sedum emarginatum,Sedum spurium 'Coccineum',Sedum lineare,Sedum sarmentosum and Sedum sarmentosum was examined by 4 methods.The results showed that at the same time the Sedum cold tolerance in field over past winter was also observed.The results showed that the cold tolerance of Sedum emarginatum was the highest;then were Sedum sarmentosum and Sedum spurium'Coccineum',and the last were Sedum sarmentosum and Sedum lineare.Compared the four methods used for examina... |
