摘要:

研究卫矛属不同种质之间的抗寒性差异,以筛选出抗寒性强的种质资源。以卫矛属10个不同种、11份不同地区白杜的1年生休眠枝条为试材,采用电导法测定其低温胁迫下的电解质外渗率,结合Logistic方程计算半致死温度LT50,对以上21份卫矛属植物材料抗寒性进行研究。结果表明,在低温处理下,所选的卫矛属植物电解质外渗率变化呈S曲线,但不同种质之间上升速率存在差异,其半致死温度范围介于-34.30~-22.55℃之间。10个不同种的抗寒性由强到弱为白杜、西南卫矛、黄心卫矛、凤城卫矛、鬼箭羽、大花卫矛、矮卫矛、栓翅卫矛、陕西卫矛、小卫矛,白杜不同地区抗寒能力由强到弱为加拿大蒙特利尔、中国山西太谷、加拿大麦吉尔、中国宁夏、中国河北承德、日本北海道、中国辽宁沈阳、中国吉林长春、中国山西榆次、中国河南南阳、中国河北邯郸。白杜、西南卫矛、黄心卫矛相较于其他品种属于抗寒性较强的品类。

Abstract:

This article aims to study the differences in cold resistance among different germplasms of Euonymus and comprehensively evaluate their cold resistance, with the hope of screening out germplasm resources with strong cold resistance. Using one-year-old dormant branches from 10 different species and 11 different regions of Euonymus, the electrolyte leakage rate under low temperature stress was determined using the electrical conductivity method. Combined with the Logistic equation, the semi-lethal temperature LT50 was calculated to study the cold resistance of above 21 Euonymus plant materials. The results indicated that under low temperature treatment, the electrolyte leakage rate of the selected Euonymus plants exhibited an S-curve, but there were differences in the rate of increase among different genotypes. The semi-lethal temperature range was between -22.55 and -34.30℃. The order of cold resistance strength among 10 different species was: Euonymus maackii> Euonymus hamiltonianus> Euonymus porphyreus> Euonymus fengchengensis> Euonymus verrucosus> Euonymus macropterus> Euonymus nanus> Euonymus phellomanus> Euonymus schensianus> Euonymus nanus. The order of cold resistance ability in different regions was Montreal, Canada; Taigu of Shanxi, China; McGill, Canada; Ningxia, China; Chengde of Hebei, China; Phuket, Japan; Shenyang of Liaoning, China; Changchun of Jilin, China; Yuci of Shanxi, China; Nanyang of Henan, China; Handan of Hebei, China. Euonymus maackii, Euonymus bungeanus, and Euonymus macropterus are relatively more resistant to cold stress compared to other varieties.

Key words: Euonymus, Euonymus maackii, low temperature stress, cold resistance, electrolyte extravasation rate, lethal temperature for 50% of the population (LT50), germplasm resources
