火麻仁种质抗性试验研究

Experimental Study on the Resistance in Fructus cannabis Germplasm

[目的]鉴定不同产地火麻仁种质抗逆性强弱,为火麻仁药材栽培引种提供科学的选择依据。[方法]采用盆栽控水、控温的方法,测定了全国各地具有代表性的21份火麻仁种质资源的抗旱、抗寒和耐涝的性能;采用大田种植,调查观测的方法测定火麻仁种质抗叶面跳甲的性能。利用隶属函数法计算各火麻仁种质资源抗性恢复指数RI值和虫口密度,综合评价了21份种质资源的抗旱性、耐涝性、抗寒性和叶面跳甲抗性,并采用加权评分法对21份火麻仁种质的抗性进行综合评价。[结果]在被测21份材料中,各产地火麻仁抗逆性综合评分为49.85~84.10,评分前3位的分别是内蒙古呼和浩特、陕西靖边和云南楚雄禄丰产火麻仁,评分最低者为贵州贵阳息烽。[结论]各产地火麻仁种质的抗逆性各不相同,在引种栽培时应根据栽培地域的气候条件选择适宜的品种栽培。

[Objective] Identify the strength of resistance germplasm in Fructus cannabis from different habitats,and provide a scientific basis for the introduction and cultivation of Fructus cannabis.[Method]Apply pot culture experiment to control the water and temperature.We had determined the drought,cold,and waterlogging tolerance of 21 copies of germplasm resources of Fructus cannabis.We apply Daejeon plant,survey and observations to determine the germplasm performance of anti-flea beetle leaves of Fructus cannabis.Through the membership function,we calculate the resistance recovery index RI and population density of insects,and evaluate the drought resistance,waterlogging tolerance,cold resistance and leaf resistance to flea beetle of 21 copies of germplasm resources of Fructus cannabis.Through weight grade method,we appraise 21 copies of germplasm resources of Fructus cannabis synthetically.[Result] In the 21 copies of the materials tested,Fructus cannabis of different habitats composite score in between 49.85-84.10.The top three are Hohhot,Inner Mongolia,Shaanxi Jingbian,Yunnan Chuxiong Lufeng.The lowest score is Guiyang Xifeng.[Conclusion] From different habitats,the germplasm resistance of Fructus cannabis varies.In the introduction and cultivation,we should choose suitable varieties cultivated based on regional climatic conditions.
