英文
peltate leaf-
In this study, systems of rapid propagation of the cultivars such as d. zingiberensis, d. panthaica and d. composite were setup to find the best way to meet the need of producing, and to establish the base of introduction, breeding and cultivar improvement of foreign dioscorea with high diosgenin ; in addition, there are two strategies to obtain polyploids combining with chromosome engineering : screeding natural mutations and mutation breeding were carred out on d. zmgiberensis. exploratively studies were done on rapid propagation of the three dioscorea plants. the result showed : explants of d. pathaica obtained the appreciate propagation efficency on ms + ba1. 0mg / l + naa0. 1mg / l, ms basic medium containing 6. 0mg - 1 ba, l. 0mg - 1 kt and sucrose at 30gl - 1 or 60g1 - 1 was the appreciate medium for microtuberization
三種薯蕷屬植物離體再生體系培養條件的探索試驗結果表明：黃山藥外植體適宜的增殖培養基為ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型塊莖誘導為ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高濃度的蔗糖含量（ 6 ）能提高微型薯蕷的誘導率，但對其誘導起關鍵作用的還是ba的濃度；菊葉薯蕷增殖效果較好的培養基為ms + ba1 . 0mg / l ，以ms培養基為誘導微型薯蕷的最佳選擇，誘導率可達50 ；盾葉薯蕷最適宜的增殖培養基為ms + ba2 . 0mg / l ，在誘導微型薯蕷的實驗中發現，當ba濃度為6 . 0mg / l和8 . 0mg / l時， 15d左右節間處膨大形成綠色圓球狀小塊，但繼續培養其上則開始分化芽。The diversities, of which 15 dioscorea zingiberensis local populations in characteristics of morphology, climate and physiology, showed the significant inner genetic diversities of the species of dioscorea zingiberensis. 2
本實驗所選的15個地方居群在形態性狀、生理性狀和物候期等的多樣性表現，說明了盾葉薯蕷存在著豐富的遺傳性狀的多樣性。By means of polyaerylamide gel electrophoresis, peroxidase isozyme, esterase isozyme and a - amylase isozyme of dioscorea zingiberensis, which were gathered from different growing environment conditions, were analyzed. with the results of 3 kinds of isozyme analysis and the analysis of 15 populations morphology and climate, dioscorea zingiberensis were divided into 5 ecotypes. the main results were shown as follows : 1
本研究以來自我國秦嶺山脈以南的甘肅、陜西、湖北、湖南、四川及雲南各省的盾葉薯蕷為試驗材料，通過對盾葉薯蕷的pox 、 est和a - amy3種酶的同工酶進行聚丙烯酰胺凝膠電泳分析，結合其形態性狀和物候期等生物學特徵，進行生態型的劃分，所得結論如下： 1
