| Abstract: | The new strain 1 of common hybrid pennisetum was selected from bud variation through vegetative propagation.Compared with the common hybrid pennisetum,the new strain 1 was shorter in both plant height and internode length,the clum was thicker and shorter,the leaf was longer and wider,the sheath was longer and the parallel distance of adjacent collar was shorter.The greater leaf rate resulted in a better herbage quality in the new strain.The content of crude protein,crude fatty,crude ash,calcium and phosphorus increased 60.0%,39.6%,24.4%,14.8% and 38.7% respectively,and the content of crude fiber decreased 13.8% in the new strain 1. |
