小麦籽粒重量(千粒重)为产量构成因子之一,向为研究者所重视。但多侧重于籽粒的形态建成、物质积累、影响因子以及增重途径等方面的研究。作为“容库”的籽粒体积与粒重关系,一般认为较大的库是小麦形成重粒的必要条件。至于组成麦粒体积的长、宽、厚度与其体积及粒重关系尚缺乏分析和系统报道。而这方面关系的明确对探讨小麦籽粒增重具有一定意义。为此作者于1981—1986年间对上述问题进行连续五年的观察。所获得的结果及对有关问题的讨论,可能对小麦籽粒增重机理以及品种选用有参考价值。故整理报道如下。
Wheat grain weight (1000-grain weight) is one of the components of yield, which is of great importance to researchers. However, more emphasis is placed on the study of grain morphogenesis, material accumulation, influencing factors and ways of weight gain. As the relationship between grain volume and grain weight of “Rongkuang”, it is generally considered that the larger stock is the necessary condition for the formation of heavy grain in wheat. As for the composition of the grain size of the length, width, thickness and size and weight relationship is still lack of analysis and systematic coverage. However, the clear relationship between this aspect is of great significance for exploring the grain weight gain of wheat. To this end the author during 1981-1986 on these issues for five consecutive years of observation. The results obtained and the discussion on the relevant issues may have reference value for the mechanism of grain weight gain and the selection of varieties. So finishing reports are as follows.
