将14份滇型杂交粳稻新品种(组合)在沈阳种植,分析其干物质积累及转移情况。结果表明:这些品种从移栽30 d至抽穗期干物质量明显增加。来自云南的品种其干物质表观转移量和干物质转移率与辽宁品种存在明显差异,其产量也明显低于辽宁品种。在供试的14个品种中表现较好的是3号,9号和13号。 14 new Dian-type japonica hybrid rice varieties were planted in Shenyang, and their dry matter accumulation and translocation were analyzed. The results showed that the dry weight of these cultivars increased significantly from 30 days after transplanting to heading stage. The apparent amount of dry matter transferred and dry matter translocation from Yunnan cultivars were significantly different from that of Liaoning cultivars, and their yields were also significantly lower than those of Liaoning cultivars. Among the 14 cultivars tested, the best ones were No.3, No.9 and No.13.
