【摘要】 以兰州百合为材料,按鳞片发育程度、切割方式及晾晒处理天数进行扦插试验,研究了这些因素对鳞茎形成的影响。结果表明:中层鳞片月增殖系数最高,腐烂率由外层向内层鳞片递减;整叶扦插比鳞片切割的月增殖系数高,扦插后腐烂率一般随着鳞片切分越细而越高。扦插前晾晒处理,可减少扦插鳞片的腐烂,提高扦插成活率。晾晒过程中鳞片色泽与生理变化对鳞茎的形成有一定的影响。更多还原

【Abstract】 The effects of physiological age, ways of cutting and drying treatment time on bulblet formation were studied with Lilium davidii varunicolor CottonThe result indicated that middle layer bud scale had the highest propagation rate.The rate of rotting of explant decreased from outside layer to interior layerIntegral leaf had higher rate of reproduction than cutting, and the smaller cutting the higher rate of rotting had.Drying treatment could reduce the rotting of bud scale and improve the rate of survival.The color and physiological changes in bud scale was connected with the formation of bulblet.更多还原
