| 中文摘要: |
| 本研究以亚美16号黄瓜为实验材料，采用室内生物测定的方法，通过比较不同配方营养液中黄瓜种子萌发及幼苗生长特性的差异，筛选出适合的水培营养液。结果表明，不同营养液中黄瓜种子的最终萌发率和发芽势没有显著差异（P>0.05），对照、配方1和配方2溶液中黄瓜种子的发芽指数相对较高，且对照中的发芽指数显著高于配方3和配方4溶液（P<0.05），对照和配方2营养液中黄瓜种子的活力指数显著高于配方1、配方3和配方4（P<0.05）。对照处理中黄瓜幼苗的根长最大，其后依次为配方2、配方1、配方3和配方4，且对照与配方2营养液以及配方2和配方1营养液处理间没有显著差异（P>0.05）；配方1和配方3营养液中黄瓜幼苗的苗高显著高于对照、配方2和配方4（P<0.05）；配方3溶液中黄瓜幼苗的单株鲜重最高（448.23±5.66mg），其后依次为配方1、配方4、配方2和对照，且配方3处理显著高于其它处理（P<0.05）。可见，配方2和配方1溶液相对较适合于黄瓜水培中的种子萌发，而配方3和配方1溶液相对较适合于其幼苗生长。 |

| Setting Yamei 16 cucumber as study materials, the proper hydroponics nutrient solution was screened through comparing the characteristics of the seed germination and seedling growth by indoor bioassay. The results showed that there were no significant differences on the seed germination rates and germination potential of the cucumber in different solutions (P>0.05), the seed germination indexes in the control, solution 1 and 2 were higher, and it was significant higher in the control than those in solution 3 and 4 (P<0.05), and the vigor indexes in the control and solution 2 were significantly higher than those in solution 1, 3 and 4 (P<0.05). The seedling root length of the cucumber in the control was the highest, successively followed by solution 2, 1, 3 and 4, and there were no significant differences between solution 2 and the control or solution 1 (P>0.05); the seedling height in solution 1 and 3 was significantly higher than that in the control, solution 2 and 4 (P<0.05), and the fresh weight per plant in solution 3 was the highest (448.23±5.66 mg), successively followed by solution1, 4, 2 and the control. So, solution 2 and 1 were relatively suitable for cucumber seed germination, and solution 3 and 1 were suitable for its seedling growth in the hydroponics cultivation. |
