  4. The study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains. with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates, it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike. the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number. the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant. the environmental changes resulted from different sowing dates mainly effected the middle spikelets development, even though the differences between wv and sv were represented in every spikelet positions. the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes, and could represent the yielid potential of the whole spikelet. the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain

    確定小麥不同小穗位和小花位發育與結實特性是實現大穗多粒的重要前提.本文通過對冬、春性小麥品種分期播種試驗得出,較高的小穗結實力是增加穗粒數的重要因素.不同播期、品種之間,小穗粒重和粒數呈現相同的化趨勢.中部以及基部小穗粒重與穗粒重之間呈高度正相關.體現的播期效應以對中部小穗發育的影響為主,而冬、春性品種的基因型差可反映在各個小穗位上.第2小花位的子粒發育狀況反映整個小穗的生產能力.結果表明,促進中部優勢小穗(第5 15小穗)結實和第1 3小花位子粒發育是提高小花結實率和穗粒重的關鍵
