采用5种不同预处理方法对新鲜和干燥的富贵籽种子进行处理;用7种不同介质对新鲜富贵籽种子进行无菌萌发及幼苗培养。结果表明:新鲜的成熟种子与干燥的成熟种子经过相同的处理后其发芽参数基本无显著差异,新鲜种子直接剥除果肉后即达到较好的发芽效果,而干燥种子在剥除果肉后还要浸种或经NaOH处理后方可;最适合富贵籽种子无菌萌发的培养介质是无菌水+滤纸和无菌水+珍珠岩;1/2MS 固体培养基中无菌幼苗的鲜重显著高于其他培养介质。
採用5種不同預處理方法對新鮮和榦燥的富貴籽種子進行處理;用7種不同介質對新鮮富貴籽種子進行無菌萌髮及幼苗培養。結果錶明:新鮮的成熟種子與榦燥的成熟種子經過相同的處理後其髮芽參數基本無顯著差異,新鮮種子直接剝除果肉後即達到較好的髮芽效果,而榦燥種子在剝除果肉後還要浸種或經NaOH處理後方可;最適閤富貴籽種子無菌萌髮的培養介質是無菌水+濾紙和無菌水+珍珠巖;1/2MS 固體培養基中無菌幼苗的鮮重顯著高于其他培養介質。

Five pretreatment ways are used to treat dry and fresh seeds of ardisia crenata and seven media used to help the seeds’ sterile germination and the nursing of seedling. The results show that there is basically no difference in germination between fresh and ripe seeds and dry and ripe ones when subjected to same treatment. The fresh seeds show a good germination after removing their flesh while the germination of dry seeds needs soaking or a NaOH treatment. The best medium for sterile germination of ardisia crenata is sterile water and filter paper or sterile water and perlite. The fresh weight of sterile seedling in 1/2MS solid medium is obviously higher than other culture media.
