薯蓣属 meaning in Chinese
dioscorea
Examples
- 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类理想的植物行为生态学研究材料：第一，攀缘植物由于受攀缘能力和支柱木资源的限制，在生长过程中通常要遇到强烈变化的环境条件(特别是光照) ；第二，攀缘植物中具有较高比例的雌雄异株类型，通常占地区攀缘植物种类的30 40左右，不同性别的植物在形态学及生物学特性、经济价值等方面存在一定的差距，因此，本文以雌雄异株攀缘植物栝楼( trchosahtheskirilowiimaxim ) (葫芦科多年生草质藤本植物)和山药( dioscoreaoppositathunb ) (薯蓣科薯蓣属植物) 、雌雄同株异花攀缘植物丝瓜[ luffacylindrical ( l ) roem ] (葫芦科一年生攀缘草本植物)为材料，试图从生理生态学及生殖生态学角度揭示攀援植物如何适应不同生境及其机理。 - 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
三种薯蓣属植物离体再生体系培养条件的探索试验结果表明：黄山药外植体适宜的增殖培养基为ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型块茎诱导为ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高浓度的蔗糖含量( 6 )能提高微型薯蓣的诱导率，但对其诱导起关键作用的还是ba的浓度；菊叶薯蓣增殖效果较好的培养基为ms + ba1 . 0mg / l ，以ms培养基为诱导微型薯蓣的最佳选择，诱导率可达50 ；盾叶薯蓣最适宜的增殖培养基为ms + ba2 . 0mg / l ，在诱导微型薯蓣的实验中发现，当ba浓度为6 . 0mg / l和8 . 0mg / l时， 15d左右节间处膨大形成绿色圆球状小块，但继续培养其上则开始分化芽。
