In the study, six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation. the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties. heterosis of spike differentiation was positively correlated with heterosis of hybrid yield. finally, the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region
對6個不同生態類型小麥品種及其完全雙列雜交f1幼穗分化特點和穗分化雜種優勢的研究表明，雜種幼穗分化各主要時期普遍存在雜種優勢；不同生態類型組配方式的雜種穗分化優勢不同；穗分化雜種優勢與產量雜種優勢具有一定相關關系；黃淮麥區雜交小麥最佳生態組配方式為春性品種冬性品種。 -
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變化趨勢.中部以及基部小穗粒重與穗粒重之間呈高度正相關.體現環境差異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異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 -
The paper systematically discusses the mechanism for glycinebetaine to improve plant salt resistance and its research advances in genetic engineering at home and abroad as well as summarizing the research progresses about the key enzymes and their genetic engineering in glycinebetaine biosynthesis. it suggests that on the basis of further understanding the mechanism for glycinebetaine to improve plant salt resistance, the transformation of the genes relating to glycinebetaine biosynthesis should be carried out in major crops so that new plant varieties resistant to salt can be obtained
