| Abstract: | 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. |
