不同种源胡枝子抗寒性和生物量变异研究
VARIATION OF COLD TOLERANCE AND BIOMASS OF LESPEDEZA FROM DIFFERENT PROVENANCES
【摘要】 对比试验表明,不同种源二色胡枝子的抗寒性和地上部分生物量有变异,其中二色(辽·海城1)、二色(内蒙古)与二色(美)和二色(豫)之间,二色(辽·西峰2)、二色(冀)与二色(豫)之间抗寒性差异显著。综合抗寒性和生物量两个因子进行评价,二色(内蒙古)和二色(冀)、二色(辽·海城1)、二色(辽·西峰2)、二色(辽·海城2)比较适合试验地的自然环境条件。
【Abstract】 Comparison experiments showed that the cold tolerance and the biomass above-ground of the different provenances are different. Cold tolerance of L.bicolor(Liaoning·Haicheng No.1), L.bicolor(Mongolia) and L.bicolor(America),L.bicolor(Henan),and L.bicolor(Liaoning·Xifeng No.2), L.bicolor(Hebei)and L.bicolor(Henan) were significantly different. Considering two factors of cold tolerance and biomass, L.bicolor(Mongolia),L.bicolor (Hebei), L.bicolor (Liaoning·Haicheng No.1), L.bicolor(Liaoning·Xifeng No.2) and L.bicolor (Liaoning·Haich eng No.2) are better acclimated to the natural conditions of the experimental site.
