天女木兰(Magnolia Parviflora Sieb),又名山牡丹,主要分布于辽宁省,在安徽、浙江省和日本、朝鲜亦有生长。我省仅见于集安县境内海拔1300米以下的沟谷地带次生林中。该树种为珍贵的观赏木本花卉和香料植物,是我省一级重点保护树种。由于野生资源极少,为适应园林绿化和香料资源开发利用,有关人工繁殖问题急待解决。我们根据对天女木兰种子具有种皮坚硬致密,限制胚的膨胀和种胚极小,发育不全的“双重休眠”生理特性的了解,采用水浸法处理种子,室内鲜种层积处理;气干种子
Magnolia Parviflora Sieb, also known as Mount Peony, is mainly located in Liaoning Province and grows in North Korea in Anhui, Zhejiang and Japan. The province only found in Ji’an County within the 1300 meters above sea level secondary forest in the valley. The species is precious ornamental woody flowers and spice plants, is a provincial level key protected species. Due to very few wild resources, in order to meet the development and utilization of landscaping and spice resources, the issue of artificial breeding is urgently solved. Based on the understanding of the physiological characteristics of “double dormancy”, which is characterized by hard and dense seed coat, limited expansion of embryos and minimal embryogenesis, the seedlings are treated with water immersion method, seed
