摘要
通过对12种紫花苜蓿种子的发芽率、发芽势、根长、芽长、鲜重、根长/芽长等6个发芽指标进行了测定与评价的分析研究。结果表明:12种紫花苜蓿种子间发芽及苗期特性差异显著,其中WL323发芽率最高,为97%;在发芽势方面,WL323最高;在根长方面,内蒙紫花苜蓿最高;在芽长方面,苜蓿3号最高;在根长/芽长方面,内蒙紫花苜蓿最高;在鲜重方面,甘肃紫花苜蓿最高。综上所述,在整体萌发特性上表现最突出的是WL323,值得在陕北地区推广。
This experiment selects 12 kinds of alfalfa seeds as the experimental material, to determine and evaluate the germination indexes including seed germination rate, root length and bud length, root/bud length. The results show that the germination rate and seedling characteristics of different alfalfa varieties varies significantly. The ger- mination rate of the variety of WL323 is the highest, 97.33% ; in terms of germination potential, the variety of WL323 is the highest ; in terms of root length, the variety of Inner Mongolian Alfalfa is the highest; in terms of bud length, Alfalfa No. 3 is the highest; in terms of root/bud length, the variety of Inner Mongolian Alfalfa is the high- est; and in terms of fresh weight, the variety of Gansu Alfalfa is the highest. Above all, WL323 is the best in all germination characteristics worth promoting in northern Shaanxi area.
