在杉木组织培养中,通过控制培养基中的细胞分裂素和生长素比例,从而有效地诱导根、茎器官的发生和完整植株的形成,已有专题报道。研究自然生长的杉木萌芽中,内源激素存在情况的结果表明,杉芽中含有三大类生长促进物质——生长素、赤霉素、细胞分裂素。除了生长素含量较低外,赤霉素和细胞分裂素的含量均较高,尤以细胞分裂素的效应最为突出。这也是造成杉木萌蘖性强的主要原因。本文将进一步研究植物激素
In the tissue culture of Chinese fir, it has been reported that the control of the ratio of cytokinin and auxin in the culture medium can effectively induce the occurrence of root and stem organs and the formation of intact plants. The study of the natural growth of Chinese fir sprout, the presence of endogenous hormones results show that the spruce contains three types of growth-promoting substances - ghrelin, gibberellin, cytokinin. In addition to the low content of ghrelin, gibberellin and cytokinin levels were higher, especially the role of cytokinin the most prominent. This is also the main reason for the strong sprouting of Chinese fir. This article will further study plant hormones
