本试验对优良牧草多年生香豌豆茎段不同部位和不同扦插基质的生根能力分别进行了观测分析.结果表明:多年生香豌豆梢部茎段扦插生根能力最强,其生根率达到66.67%,根长、根表面积和根体积极显著(P<0.01)高于其它茎段.地上部分生长状况为新叶数之间差异不显著而新梢高之间显著(P<0.05);混合基质扦插的生根能力最强,其生根率达到65.3%,且根表面积和根体积极显著(P<0.01)高于其它基质.地上部分的生长状况为新叶数之间差异显著(P<0.05)而新梢高之间不显著.

The effects of different stem parts and different cutting mediums on the rooting of the cutting of everlasting pea(Lathyrus latifolius L.) were studied. The result showed that the top part of stem of everlasting pea had the best rooting capacity. In the stem cutting experiment, it had better effects on rooting rate (66.67%) and the length, surface area and and volume of root. All index of root system was extremely significant compared with other parts (P<0.01);In the growth performance of overground part, no significant difference was observed on the average new leaves of stem cutting, but new shoot length was different (P<0.05). The mixed media had the best rooting capacity in different medium experiments, in which the rooting rate was 65.3% that was better than others, and the surface area of root and root volume of root system index were significantly different from other mediums (P<0.01);but the growth status of overground part was not as well as the mixed media, and there was a significant difference in new leaves (P<0.05), but no difference in new shoot lengh.
