| 中文摘要 | This paper studied the reproductive strategies of Kobresia humilis in alpine meadow about its sexual reproduction ,vegetative reproduction and reproductive efforts respectively. The results show that the seed output of Kobresia humilis is 715. 5per unit (m2) . The germination is above 60 % in fit condition ,while only about 3 % in field. There is only 16. 13 % seed which get into seed bank and remain vitality till grass greening. So the seedling is only 3. 46 per unit (m2) in field.But the new ramets of Kobresia humilis are 711. 34 unit (m2 ) from vegetative reproduction. In addition ,vegetative reproductive effort is more than sexual reproductive effort . It constitutes 93. 5 % of all reproductive efforts. Therefore ,the main reproductive strategy of Kobresia humilis is vegetative reproduction ,and sexual reproduction is secondary in alpine condition. |
