连续观察了花生花器分化过程与营养生长间的关系,明确主茎展开叶片数可做为花器分化过程的外部指标。开花始期前主茎及各分支生长可以叶片数目做为判断幼苗生长正常与否的指标之一。同时研究了幼苗期花芽分化与后期结果之间的数量关系,早熟品种幼苗花芽分化数量占总开花数的比例较大。也分析了光、温条件对幼苗生育的影响。最后探讨了观察结果与前人的异同之处。花生是陆续开花陆续结果的作物,其产量的高低主要决定于开花结果期开花及结果数量的多少,同时也是从发芽出苗之后一系列生育过程的最终结果。开花结果期开花结果与开花期以前幼苗生育状况之间的关系如何;这些花果的花芽及其所在节位在苗期何时形成;花芽分化过程中内部形态与茎叶生长之间的关系如何。观察研究这些相关关系,了解实质.以便在苗期采取有效措施,使幼苗生育健壮,为花多果多打下基础。为此,首先从分析幼苗生育特点,我们观察研究:(1)花器形成过程各时期幼苗形态特点与营养器官生长的关系。(2)开花始期前营养生长特点及花器形成数量的初步统计。(3)开花始期前营养生长特点与成熟时饱果所在节位的比较。(4)温度、光照对幼苗生育的影响。
The relationship between the differentiation of peanut flower organs and the vegetative growth was continuously observed. It was clarified that the number of leaves in the main stems could be used as an external indicator of floral differentiation. Before flowering, the main stems and branches can grow as one of the indexes to judge whether the seedlings grow normally or not. At the same time, the relationship between the number of flower bud differentiation and the result of late seedling stage was studied. The percentage of flower bud differentiation of early maturing seedling in the total flowering number was larger. The effects of light and temperature conditions on seedling growth were also analyzed. Finally, we discuss the similarities and differences between the observed results and their predecessors. Peanuts are the result of successive flowering of crops, the level of its output mainly depends on the flowering period and the number of results flowering, but also from the sprouting emergence of a series of fertility after the final result. The relationship between the flowering fruiting stage and the seedling growth before the flowering stage; the flower buds of these flower buds and the node loci where they are formed at the seedling stage; what is the relationship between the internal morphology and stem leaf growth during flower bud differentiation? . Observe and study these related relationships and understand the essence so as to take effective measures at the seedling stage to make seedlings robust and lay the foundation for more fruit trees. To this end, first of all, from the analysis of the characteristics of seedling growth, we observed and studied: (1) the relationship between the morphological characteristics of seedlings and the growth of vegetative organs in each stage of floral formation. (2) The characteristics of vegetative growth before the flowering period and the preliminary statistics of the number of flower formation. (3) The characteristics of vegetative growth before flowering are compared with that of full fruit when flowering. (4) temperature, light on seedling growth.
