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。 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 bieolor(America) ,L. bleolor( Henan), and L. bieolor( Liaoning · Xifeng No. 2), L bicolor(Hebei)and L bicolor(Henan) were significantly different. Considering two faetors of cold tolerance and biomass, L. bieolor(Mongolia) ,L bicolor (Hebei), L blcolor (Liaoning · Haicheng No. 1 ), L. bicolor( Liaoning · Xifeng No. 2) and L. bicolor ( Liaoning . Halch eng No. 2) are better acclimated to the natural conditions of the experimental site.
