前言 山核桃(Carya cathayensis)为我国重要干果和木本油料树种。为了研究它的结实规律,六十年代起我们就陆续进行了枝、芽发育状况及其与开花结果关系的观察研究。观察内容有:芽的特性、生长动态、发育状况及其与枝梢形成的关系;枝梢种类、特性及其在个体不同发育阶段的变化情况;春梢发育状况与开花结果及育芽能力之间的关系等。研究方法是:选择标准地、标准株,进行常年定位、定时观察,测定芽、梢的粗度、长度等,同时对芽、梢进行解剖观察。现就观察研究结果报道于下:
Introduction Carya cathayensis is an important species of dried fruits and woody oilseeds in China. In order to study its strong law, from the sixties onwards, we gradually carried out the branch and bud development and its relationship with the flowering of the observation and study. Observations include: bud characteristics, growth dynamics, development status and its relationship with the formation of shoots; shoots of species, characteristics and their different developmental stages of individual changes; spring shoot development and flowering and budding ability The relationship between. The research methods are: selecting standard and standard strains for perennial positioning, regular observation, determination of buds, shoots of the coarseness, length, etc., while the buds, shoots for anatomical observation. Now observe the research results reported in the next:
