| Abstract: | This test was used Leymus chinensis cv.Jisheng and wild Leymus chinensis seeds as the materials.And the effect of soaking time(24,48,72 h)and different 2,4-D concentrations on the germination and seedling growth of two type seeds was determined,respectively.The concentration of which 2,4-D increased the germination of both seed were kept between 0.1-1 mg·L-1.When the concentration exceed 5 mg·L-1,the germination of both seed were inhibited in different degrees.The length of young seedling and young root of Leymus chinensis cv.Jisheng increased significantly through soaked by 1 mg·L-1 2,4-D for 48 h,while 2,4-D treatment had no significantly increased on the length of young seedling and young root wild Leymus chinensis seeds. |
