| Abstract: | In this study,three ryegrass varieties Knight,Peak and VNS were used as the researched objects,their seed germination and seedling growth were observed,some growth indexes such as relative germination rate,germination potential and length of root system were measured,and several physiological indicators including relative moisture content,free proline content and cell membrane permeability were studied.The results showed that the drought resistance capacity of tested perennial ryegrass varieties had the fol... |
