摘  要:
用0、5、10、20、40 mg/mL青稞秸秆水浸提液对甘肃贝母种子进行浸泡发芽试验,结果发芽率呈现出由低到高再到低的趋势。当青稞秸秆水浸提液浓度为20 mg/mL时甘肃贝母的发芽率最高,为86.21%,发芽势最高,为92.86%,发芽活力最高,为44.09,发芽指数最高,为12.02,且不同浓度间发芽率差异极显著。试验中还发现,胚根比胚芽先生长,同种浓度下,胚根比胚芽长。在实际生产中,适当把握秸秆还田量,可以降低化感作用对甘肃贝母发芽的抑制。

摘  要:
The trial of different concentration(0, 5, 10, 20, 40 mg/mL) of Hullessbarley straw aqueous extract on germination of Fritillaria przewalskii was conducted. The results showed that at different concentration of Hullessbarley straw aqueous, germination rate increased first, then decreased. When the concentration of Hullessbarley straw aqueous was 20 mg/mL, the highest germination rate(86.21%), the strongest germination powe(92.86%), the greatest germination activity(44.09) and the biggest germination index(12.02)were gotten for F. przewalskii, and there was significant difference of germination rates at different concentration of Hullessbarley straw aqueous extract at 0.01 level. In the trail, radical grew faster than germ, and radical was longer than germ in the same concentration of Hullessbarley straw aqueous extract. It was suggested that in agricultural production, appropriate quantity of straw returning could reduce the allelopathic effect on germination inhibition of F. przewalskii.
