摘要
对不同退化程度下的矮嵩草和高山嵩草无性系繁殖特性进行了初步研究。结果表明不同退化程度下两种嵩草有性繁殖能力较弱,种子生产能力低,其中中度退化草地上高山嵩草每有效穗最高只产生2粒种子,重度退化草地矮嵩草每有效穗最高只产生3.6粒种子。
The seed production of kobresia pygmaea and K. humuilis under different degenerative gradation in Alpine Meadow were studied. The results were showed that the clonal propagation ability of two species was very stronger than sexual propagation in seed. The sexual propagation ability of clonal K. pygrnaea and K. humulis were week in which seeds were only two per effective rea of plant in medial degenerative gradation and heavy gradation only 3.6.
