摘要
以栽培的 2年生细叶百合 (Lilium pumilumDC .)鳞茎为扦插材料 ,将鳞茎分内、中、外三层剥取其鳞片 ,观察鳞片在不同温度、光照强度、基质中的扦插生小鳞茎的效果。扦插 40d时 ,鳞片基本枯萎 ,此时的实验结果是 :①影响扦插效果的重要因子是温度和光强 ,2 5℃高温避光生鳞茎最佳 ;其次是鳞片位置 ,中鳞片和外鳞片好于内鳞片 ;基质对扦插影响不大。②每百鳞片生小鳞茎数和小鳞茎直径呈正相关。③相同条件下 ,相同部位的刀切鳞茎段所产生小鳞茎数量明显高于手掰的整片鳞片 。
Scales from inner, middle and outer layers of 2-year-old L. pumilum bulbs were propagated different stroma under different air temperatures and light intensities. Results showed that the most important factor influencing bulblet quantity and diamiter was temperature and light intensity, followed by scale position.Bulblets grew best at 25℃ and dark condition. Stroma had no impact on bulb propagation. Middle and outer layer scales produced more bulblets than inner ones, and average diamiter of bulblets produeced from middle and outer layer scales was larger than those from inner ones. Scales almost withered after 40 days. Weight of per 100 scales and quantity of bulblet has positively correlation to bulblet diameter. Under same condition, the quantity of bulblet reproducted by the section cut with knife is remarkablely higher than by the section broken off with hands.
