子叶是胚的重要组成部分。据前人研究,许多植物的子叶对植株的生长发育关系非常密切。如人工损伤丝瓜的子叶,使雌花形成受到抑制。棉花的种子如果子叶受伤,即会导致长成的棉株结果少。当前,人们对油菜子叶的生长状况及其作用研究的还不多,特别是植物分类学的发展,它不仅以植物外表形态来进行分类,还进而以内部结构特征来做为分类依据。为此,我们对甘兰型油菜子叶进行观察,了解子叶内部结构,生长特点及其与真叶的关系,为教学、科研、生产提供依据。为分类研究收集资料。
Cotyledons are an important part of the embryo. According to previous studies, cotyledons of many plants are closely related to the growth and development of the plant. Such as loofah artificial damage cotyledons, so that female flower formation is inhibited. If the cotyledons of cotton seeds are damaged, the result will be less cotton plants grow. At present, there is not much research on the growth status and its function of cotyledon cotyledons, especially the development of plant taxonomy. It not only classifies the appearance of plant, but also takes the internal structure characteristics as the classification basis. To this end, we observed the Brassica napus cotyledons to understand the internal structure of cotyledons, growth characteristics and its relationship with the real leaf, for teaching, research and production to provide the basis. Collect data for classification studies.
