| Abstract: | Quantity characteristics of reproductive and nutritive growth of Stipa grandis and S.baicalensis were studied in the dominant stipa population of Hulunber prairie with random sampling method.The results showed that the variation coefficient of vegetative and reproductive characteristics ranged from 6.9% to 77.6% for S.grandis and S.baicalensis respectively.The indices of sexual reproduction characteristics of S.baicalensis such as number of spikelet per spike,number of floret per spike,spike weight,the grai... |
