This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ). secondly, there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism, and hence a gap between male and female plants on morphology, biological characteristic, economic value and so on. this dissertation focuses on herbaceous climbing plants, perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb, and monoecious luffa cylindrical ( l ) roem, it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present, due to overuse of chlorofluorocarbons ( cfcs ), the ozonosphere has become thinner and thinner, and the ultraviolet - b ( uv - b ) radiation has increased considerably

而攀援植物本身是一類理想的植物行為生態學研究材料：第一，攀緣植物由於受攀緣能力和支柱木資源的限制，在生長過程中通常要遇到強烈變化的環境條件（特別是光照） ；第二，攀緣植物中具有較高比例的雌雄異株類型，通常佔地區攀緣植物種類的30 40左右，不同性別的植物在形態學及生物學特性、經濟價值等方面存在一定的差距，因此，本文以雌雄異株攀緣植物栝樓（ trchosahtheskirilowiimaxim ） （葫蘆科多年生草質藤本植物）和山藥（ dioscoreaoppositathunb ） （薯蕷科薯蕷屬植物） 、雌雄同株異花攀緣植物絲瓜[ luffacylindrical （ l ） roem ] （葫蘆科一年生攀緣草本植物）為材料，試圖從生理生態學及生殖生態學角度揭示攀援植物如何適應不同生境及其機理。

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 germplasm of medicinal plant is the key in the course of plant medicine producing. lt has direct relation to cultivation of medicinal plant and the quality of crude drug. at present, there is a large - scape area in the cultivation of dioscorea plant with high diogenin, but for neglecting the unstability of germplasm and breeding of valuable cultivars, the quality is not enough to use as crude drug, which lead to supply falling short of demand. therefore, keeping stability of good germplasm, as well as breeding new dioscorea cultivars with high diogenin and yield is urgent and valuable to study

在我國，盾葉薯蕷和穿龍薯蕷等因為較高的薯蕷皂甙元含量，都有很大的栽培面積，但作為原料藥其產量和質量並未達到植物藥生產所需，導致市場供需矛盾十分突出，就是因為只簡單地將野生資源挖回來種植，忽略了種質的不穩定和有栽培價值的品種的培育，因而保持優良種質的穩定性和培育高含量、高產量的薯蕷新品種是一個緊迫而又有價值的研究課題。
