| 摘 要： | 为了充分利用水稻自身遗传特性，减少寒地氮肥施用量，为抗低氮胁迫育种提供依据，采用土培盆栽法，对寒地粳稻110份不同基因型种质材料进行了抗低氮胁迫能力的研究。结果表明，不同基因型水稻种质材料对低氮胁迫的抗性差异显著，根据平均隶属函数值，筛选出了抗性强的材料6个，抗性弱的材料8个。分蘖期的单株绿叶数、单株分蘖数和收获期的稻草产量、有效分蘖数、穗长、单穗小穗数、穗粒数、穗粒重及稻谷产量性状对低氮胁迫反应敏感，可作为筛选各基因型水稻抗低氮胁迫能力的性状指标。 |

| Abstract: | In order to use the hereditary properties of japonica rice, reduce N applying rate and supply a foundation in rice breeding programme, the resistance of japonica rice to N stress was investigated. 110 different japonica rice germplasms were used in a soil pot culture and a field plot trial respectively. The main results were showed as following: the difference of the resistant ability to nitrogen deficiency between each individual rice germplasms used in the experiment was significant. According to the aver... |
