摘　　要：从种子不同着生部位、成熟度采样，经过含水率、粒级分配、英壳率、千粒重、发芽率等分析，结果表明草木樨黄熟期、一级侧枝采种，不仅种子量多、产量高，而且千粒重、发芽率、活力指数均高，品质近于完熟期和主茎部位的种子，种用性状优异。Sweet clover(Melilotus albus)seeds were sampled in different maturing phases and from inflorescencesat different branches of the plant.The seeds were analysed for the items of moisture content,size grading,percentage of pod shells,thousand一grain weight,germination percentage and others.It was shown thatthe seeds from the secondary branches in the yellow一ripe phase of the plant were of high yield and of highquality with respect to the indices of thousand一grain weight,germination percentage and vitality whichwere similar to those of the seeds from inflorescences at the main stem in the full一ripe phase of the plant.
