摘要: 以川农麦1号为材料,研究了S3307不同浓度拌种对不同播期小麦生育进程的影响。结果表明,S3307除使三叶期随浓度的增加而提前外使其它各生育时期均退迟;使幼穗分化从小花到药隔的分化历期显著延长;增加了结实小穗数,提高了穗粒数。

Abstract: The effects of S3307 applied to seeds with different concentrations on growth and developoment of winter wheat CV.8539 under four sowing dates were studied. The results showed as follows. S3307 treatments make appearing of three leaf stage early, but delay the other stages. S3307 treatments lengthen the duration from floret differentiation stage to yaoge stage, increase the spikelet number and grain number per ear.

Key words: S3307, WITER WHEAT, DEVELOPMENT OF EAR
