六种根茎类禾草种子产量构成因子和种子生产性能的研究

Studies on Seed Yield Components and Seed Production Performance of Six Rhizomatous Grasses

对 6种根茎类禾草的种子产量构成因子作了研究 ,并通过测试单穗种子数、结实率、千粒重及单位面积种子产量等指标对其种子生产性能进行了比较。由结果可知 ,巴顿牧冰草的种子生产性能最高 ,茹莎娜牧冰草的种子生产性能最低 ,其它 4种牧草居中。

A study was performed on the seed yield components of six rhizomatous grasses and the seed production performances of them were compared in the seed number of single ear, Fruit rates, thousand grain weight and seed yield per unit area, etc. The results showed that the seed production performance of Pascopyrum smithii barton is the highest, while the Pascopyrum smithii rosana's is the lowest, the rest species are moderate.
