| 摘 要： | 用0.3%、0.6%、0.9%和1.2%的NaCl溶液分别对不同秋眠等级的10种紫花苜蓿种子进行处理,观测其在不同盐浓度处理下发芽率.结果表明:浓度和品种对发芽率的影响均显著.随着盐处理浓度的增加,发芽率一般呈下降趋势.将不同盐溶液处理10 d的种子转移到蒸馏水后,原来较高盐浓度下的种子具有较高的萌发恢复率.0.6%、0.9%、1.2%的盐浓度下种子萌发率和萌发恢复率要比蒸馏水中的低,表明NaCl处理后的部分种子永久地失去了萌发活力. |

| Abstract: | Salt tolerance of 10 alfalfa varieties in geminating period have been studied by measuring the germination rate under the treatments with 0.3%,0.6%,0.9% and 1.2% NaCl solution.The experimental results indicated,that the difference of the germination rate for alfalfa varieties in the same NaCl concertration was significant,that the difference of the germination rate for the same variety in the different NaCl was also significant.In general,the percentages of germination declined with salt concentration incre... |
