一个大麦良种,由于栽培措施不同,造成单产之间差异。产量低的主茎或分蘖之间的穗粒数差别大;大、中、小穗的结实率显著不同;各自的籽粒大小更不一样。这三者互相差别在支配生理过程的库(根茎)或源(叶、绿色叶鞘两者因素中),那个影响为主呢?本文根据1985年大麦品种区域试验的室内考种时,发现大麦地上第一节位茎粗硬与穗粒数量成正比,与剑叶、倒2叶面积构成不规则曲线。从而推断大麦茎粗硬即生理 A barley variety, due to different cultivation measures, resulting in differences between yields. The difference in the number of grains per spike between the main stems or tillers with low yield was significant. The seed setting rates of big, middle and spikelets were significantly different. The grain size of each was more different. The difference between the three in the control of the physiological processes of the library (rhizome) or source (leaf, green leaf sheath both factors), the impact of the main? In this article based on the regional test of barley varieties 1985 test, The first section of stalk hard and spikelets is proportional to the number, and the flag leaf, down 2 leaf area constitutes an irregular curve. Thus inferred barley stalk rough that is physiology
