摘要/Abstract

摘要： 对10个紫花苜蓿品种的花萼直径、花蜜量、访花蜜蜂数量和种子产量进行了研究,结果表明,紫花苜蓿的单位面积花蜜量与访花蜜蜂数量呈极显著正相关(r=0.93^**),访花蜜蜂数量与种子产量呈显著正相关(r=0.87^*);紫花苜蓿的花蜜量与花萼直径呈极显著正相关(r=0.99^**);紫花苜蓿品种赛特(Sitel)和德宝(Derby)在兰州地区能获得高产、优质的种子。

Abstract: This paper studied calyx diameter,nectar amount,the number of visiting bees and seed yield of ten alfalfa varieties.The results showed that there were significant correlations between nectar amount per m² and the number of visiting bees,the number of visiting bees and seed yield,as well as calyx diameter and nectar amount per m²,with the r value 0.87,0.93 and 0.99 respectively.Sitel and Derby varieties in Lanzhou area could produce seeds with high yield and good quality.
