摘要
为了八角莲资源的可持续发展提供基础和科学依据。运用人工授粉方法,统计其结实率;用不同的样株进行人工补种,统计其成活率。经过人工授粉处理,庙坝石人山、松丰对窝山、槐坪山的八角莲结实率分别由8.1%、5.0%、2.5%提高到73.4%、91.6%、30.0%;人工补种八角莲栽培苗、种子苗、组培定植苗、组培苗,成活率依次为,96.7%、93.3%、50.0%、15.0%;定植1年,根部增重依次为80%、86.2%、103%、120%。人工授粉有效的提高了野生八角莲的结实率;人工补种方式能够有效的增加八角莲的种群数量及种群内个体数。
To provide material and scientific evidence for the sustainable exploitation of Dysosina vers Artificial pollination and resowing was carried out for Dysosina versipellis. Through artificial pollination, the flower ripening rates in Miaobashirenshan, Songfengduiwoshan and Huaipinshan increased from 8.1%, 5.0%, and2.5% respectively to 73.4%, 91.6% and 30.0% respectively; With artificial resowing of cultivated Dysosina versipellis, cultivated seedlings, cultivated tissue culture seedling and tissue culture seedling, the survival rates were 96.7 %, 93.3%, 50.0%and15.0% respectively. After one year, the weight of roots increased 80.0%,86.2%, 103% and 120%. Artificial pollination markedly increases the ripening rate of Dysosina versipellis, and artificial resowing increases the number of species group and the number of species within the species groups.
