对典型草原120种植物种子的大小及其重量进行了研究，其结果如下：120种植物分属于29科80属.据12组20粒种子重量的平均值，黄蒿种子的重量最轻，为0.758±0.361 mg;芯芭种子最重，为1 625.616±806.434 mg.草原植物以小粒种子为主，50 mg以下的种子占总量的66.67%;从1 000到1 700 mg的种子仅占1.67%.植物生活型(生长型)与种子大小、重量和散布形式有关，在典型草原上，以多年生草本植物为主，占总数的77.50%；其次为一年生草本和二年生草本植物，分别占8.33%和6.67%.种子数量与种子重量之间有一定的相关关系，而且均达到极显著的水平.

The seed size and weight of 120 plant species in typical steppe was researched.The results showed that:these 120 species belong to 80 genera in 29 families.According to the average seed weight obtained by 12 groups with 20 grains for each group,the seed of Artemisia scoparia is the lightest,0.758±0.361 mg,while the seed of Cymbaria dahurica is the heaviest,1 　625.616±806.434 mg.The plants with small-size seeds in steppe are the majority.The seeds lighter than 50 mg hold 66.67% and only 1.67% seeds weigh from 1 　000 to 1 　700 mg.The size,weight and form of seeds relate to the life form (or growth form) of plant.In typical steppe,the perennial herbs are the major and hold 77.50% of all the plants,the others are annual and biennial herbs,holding 8.33% and 6.67% respectively.There are some correlation between the amount and weight of seeds,and the correlation comes up to the extreme significant level.
