【摘要】 研究了不同浓度GA3对沙枣(Elaeagnus angustifolia)种子发芽率和出苗率的影响。结果表明,在50～150mg.L-1范围内,不同质量浓度的GA3对沙枣种子发芽和出苗均有显著促进作用(P<0.05),质量浓度为100mg.L-1时效果最好,室内发芽率为86.3%,圃地出苗率为73.6%。更多还原

【Abstract】 A experiment was conducted to determine the effects of different solutions GA3 on the germination rate and emergence of Elaeagnus angustifolia seeds,This study indicated that the GA3 with 50~150 mg·L-1 solution significantly increased the germination rate and emergence of E.angustifolia seeds,and the optimal solution of GA3 was 100 mg·L-1,in which the germination rate of E.angustifolia seeds in laboratory was 86.3% in laboratory and was 73.6% in nursery..更多还原
