| 中文摘要: |
| 六福A（籼型不育系）尧丰优2 号（籼型三系杂交稻）尧连粳11 号（粳型常规稻）等3 种不同品种水稻在不
同水分胁迫和不同形式的氮素的影响下、观察分析其幼苗产生的一些变化。结果表明院不同品种水稻的叶部和根部
的硝态氮的含量、均随着营养液中硝态氮含量的增加而增加。一定的水分胁迫（10%PEG 溶液）可以较为明显地增加
叶部和根部中硝态氮的含量。氨态氮则与硝态氮有相同的反趋势；一定程度上的水分胁迫对根系的生长是有利的、
导致的根系的生长加快、但各品种水稻的增幅有所不同。 |
| 英文摘要: |
| Rice genotypes including Liufu A, Fengyou NO2, Lianjing NO11 grew under different water stress condition
and the impact of different forms of nitrogen were observed and analyzed on the changes arising from its seedling. The
results showed that: nitrate content of different varieties of rice leaf and root increased with increasing nitrate nitrogen
concentration in the nutrient solution. Water stress (10% PEG solution) could significantly increase the contents of leaves
and roots of nitrate. Ammonia nitrogen and nitrate have the same anti-trend; certain degree of water stress on root growth
was beneficial, due to accelerating the growth of root system, but the increases of all varieties of rice increased differed. |
