[Effects of storage conditions and sowing methods on seed germination of Leymus chinensis].
This paper studied the effects of four storage conditions (dry storage at 4 degrees C, dry storage at room temperature, storage in moist non-saline-alkali soil at 4 degrees C, and storage in moist saline-alkali soil at 4 degrees C), three germination substrates (filter paper, non-saline-alkali soil, and saline-alkali soil), and two sowing methods (sowing on and in the substrates) on the seed germination of Leymus chinensis. The results showed that compared with the dry storage at room temperature, dry storage at 4 degrees C improved the germination velocity significantly, but had less effect on germination rate. When stored in moist saline-alkali soil, the germination rate was only 28.8%, in contrast to 73.7% in non-saline-alkali soil. With different sowing methods, the seed germination rates of L. chinensis was in the order of sowing on the surface of non-saline-alkali soil (89.3%) > between papers (68.0%) > on papers (64.0%) > in non-saline-alkali soil (61.3%) > on the surface of saline-alkali soil (25.6%) > in saline-alkali soil (6.0%).
