| 摘 要： | 对盘锦地区水稻的几个主栽品种及有生产潜力的新品系,在种子发芽和不同生育时期的耐盐临界浓度及不同盐分抑制条件下的水稻生长状况进行研究。结果表明:水稻种子耐盐能力排序为辽盐糯>辽粳294>盐丰47>辽盐188>辽优2006>辽粳263>沈农9765>辽盐166>辽粳138>辽盐92;在不同生育时期供试水稻品种的耐盐能力排序为:发芽期辽盐糯>辽粳294>盐丰47>辽盐188>辽优2006>辽粳263>沈农9765>辽盐166>辽粳138>辽盐92;分蘖期盐粳68>H522>H757>辽盐166>辽盐188>K20;拔节-抽穗期辽盐166>辽盐188>盐粳68>K20>H522>H757;成熟期辽盐166>辽盐188>盐粳68>H757>H522>K20。

| Abstract: | using rice cultivars planted on a large scale in Panjin area and some promising lines as entries,the seed germination and salt-tolerant limitation at different growth stage and the growth situation of rices under different sat concentration were studied.The results showed that the order of seed salt-tolerant ability was Liaoyannuo>Liaojing 294>Yanfeng 47>Liaoyan 188>Liaoyou 2006>Liaojing 263>Shennong 9765>Liaoyan 166>Liaojing 138>Liaoyan 92.The orders of salt-tolerant ability of plants were Liaoyannuo>Liaojing 294>Yanfeng 47>Liaoyan 188>Liaoyou 2006>Liaojing 263>Shennong 9765>Liaoyan 166>Liaojing 138>Liaoyan 92 at sprouting stage,Yanjing 68>H522>H757>Liaoyan 166>Liaoyan 188>K20 at tillering stage,Liaoyan 166>Liaoyan 188>Yanjing 68>K20>H522>H757 from jointing to heading stage,and Liaoyan 166>Liaoyan 188>Yanjing 68>H757>H522>K20 at maturity stage. |
