东方百合试管鳞茎驯化移栽研究

Study on Acclimatization and Transplanting of Bulblet in Vitro of Oriental Lily

以东方百合‘西伯利亚’的试管鳞茎为材料,研究试管鳞茎的根长及直径大小、移栽基质等因素对移栽效果的影响,结果表明:A2(进口草炭∶蛭石∶珍珠岩为7∶1∶2)基质是百合试管鳞茎驯化移栽适宜的基质,其移栽成活率、鳞茎鲜重及鳞茎围径都显著高于其他处理;根原基≤1.5cm时移栽成活率高,根系长度大于3.0cm移栽成活率低;试管鳞茎直径越大,移栽成活率、抽薹率、鳞茎鲜重及鳞茎围径越大,试管鳞茎直径大于1.5cm时移栽成活率、抽薹率最高。

In our paper, bulblets in vitro of oriental lily cv. ‘ Siberia ’ was used as materials to study effect of root length and diameter of bulblet and transplanting substrates on transplanting results. The results showed that A2 substrate （imported turf： vermiculite： pearlite=7： 1：2） was the best one to acclimatize and transplant the bulblets, showingsignificantly higher transplanting survival rate, fresh weight and girth of bulblet than that ones in other substrates. When root primordium was under 1. 5 cm, transplanting survival rate was higher. When root length was over3. 0 cm, transplanting survival rate was lower. The higher the bulblet diameter was, the higher transplanting survival rate, bolting rate and bulblet girth were. When bulblet diameter reached over 1. 5 cm, both transplanting survival rate and bolting rate were highest.
