多棱大麦生育期生态效应分析

ECOLOGICAL EFFECTS ANALYSIS OF MULTI-ROWED BARLEY GROWTH STAGE

控制不同生育阶段的基因型对环境的敏感程度不同，不同播区的效应也呈现较大的差异。结果表明：同一品种春播时，基因与环境互作较高从效应因子看：北纬度效应＞海拔＞降雨量＞日照时数＞大于０℃积温＞经度。从效应方向看：海拔、秋播区北纬度、春播区降雨和日照时数呈正向效应；其它因子则呈负向效应。

The sensitive of the gene type to control growth stage is different for factors.The effects in sowing area are great difference.The results in spring sowing areas is higher than in other sowing areas.In different factors:the effects of north latitude>elevation>rainfall>hours of sun> higher 0℃ accumulation tern6erature> longitude,the effect direction:the effects of elevation,north latitude in fall sowing areas rain fall in spring sowing area and haurs of sun are positive.Other factors are negitive.
