摘要
采用电导法和回归系数b值分析,对外引沙棘不同品种的抗寒力进行测定.结果表明,由俄罗斯引进的7个品种(其中一个品种为雄株)均较对照野生中国沙棘亚种抗寒力强;而其中的6个雌株品种又均较雄株品种的抗寒力强;其6个雌株品种的抗寒力顺序为‘楚伊沙棘”、“巨人沙棘”、‘浑金沙棘”、“金色西伯利亚沙棘”、“卡图尼礼品沙棘”、“丰产沙棘”.测定结果与1990~1996年连续7年引种试栽的越冬表现观察结果基本一致。
We have conducted studies on cold-resistant abilities of sea-buchthorn cultivars introduced frm Russia by conductance and regression analysis.The results indicated that the abilities of 7 cultivars(including one male cultivars) were all greater than that of Hippophae sinensis L.ssp.sinensis Rousi(CK). The abilities of 6 female cultivars were greater than that of male cultivar.If arranged in cold-resistant ability order from great to small, the 6 female cultivars were listed as follows: Yicu, Juren, Huijing, Golden siberia, Cartoni, Fengchan. The above-metioned results determined by conductance consist basically with 7year's field observation from 1990 to 1996.
