摘要
对香叶天竺葵组织培养快速繁殖技术进行了研究,建立了种苗快速繁殖技术规程.结果:适宜的增殖培养基为MS+6-BA为0.5～1.0 mg/ L,继代周期为25～30 d,繁殖系数5以上;生根培养基为1/ 2MS+IBA 0.2 mg/ L,生根诱导率达100 %;生根培养20 d后,将试管苗移栽到菜园土:河沙=1:1的混合基质中,保湿培养,移栽成活率达98.6 %.
The propagation technique of Pelargonium graveolens L.Her in vitro were studied and a method for high frequency propagation was established. The results showed that the appropriate medium for different culture stages were： （i）Differentiation and subculture of rosette buds： MS ＋ 6-BA 0.5 - 1.0 mg/L;on this medium shoot multiplication occurred at a up to 5-fold rate after 25 days; （ii）Rooting： 1/2 MS -IBA 0.2 mg/L. In 20 days for rooting, the shoots could be directly rooted in transplantation medium （soil and sand in equal proportion） with 98.6 % survival.
