中国地生兰有性繁殖所产生的种子,因发育不全,必须与其共生的兰菌结合,才能完成萌芽而传代。然而这种结合的机率在自然界中是极为罕见的,自然界中的兰花繁殖主要是靠无性繁殖进行的。 兰花的根、茎(假球茎、地下走茎)、叶、芽等,唯独假球茎才具有自然繁殖的能力,其它营养器官必须采用组织培养才能成株。 中国地生兰的无性繁殖过程中具有如下的几个生物学特性: 1、三代同堂的生活史:假球茎是附着叶片、花苔、根系的重要器官,具有贮藏水份和养份的功能,是兰花分孽的物质基础。
Due to the incomplete growth of the seeds produced by the sexual reproduction of Chinese Landrace, it must be combined with its symbiotic Lan Lan to complete its germination and passage. However, the probability of this combination is extremely rare in nature, orchid breeding in nature mainly by cloning. Orchids roots, stems (pseudobulbs, underground walking stems), leaves, buds and so on, but only pseudobulbs have the ability to reproduce naturally, other vegetative organs must be used in tissue culture in order to plant. The process of asexual reproduction of Chinese landraces has the following biological characteristics: 1. The life history of three generations: pseudobulbs are important organs with attached leaves, flower moss and roots, and have the functions of storing moisture and nutrients , Is the material basis for orchid division.
