愈伤素 traumatin 为植物愈伤激素的同义语。是1937年J.English、J.Bonner根据能诱发菜豆幼荚细胞分裂而具有活性的物质命名的。广泛存在于植物中,而在动物中则不存在。其化学成分已明确的仅是愈伤酸(traumaticacid)。
本文首次报道从紫金牛属植物的愈伤组织中检出岩白菜素。
This is the first report of obtaining bergenin from calli of Ardisia spp.
对于愈伤组织的再分化,不仅需要细胞分裂素,而且诱导培养基中生长素浓度的影响也是显著的。
With regard to the callus redifferentiation, not only kinetin is needed, but also the effect of auxin concentration of the induction medium is also remarkable.
外源生长素和细胞分裂素是诱导离体培养细胞分化与增殖所必需的,2,4-D是诱导胚性愈伤组织的重要激素。
The exogenous auxin and cytokinin are necessary to induced differentiation and proliferation of cells of culture in vitro. 2,4-D is an important hormone of induced embryogenic calluses.
