Dhawan et al. Dioscorea bulbifera L. (Family: Dioscoreaceae) commonly known as ‘air potato’ is an important edible medicinal plant use to treat a wide range of diseases. Dioscorea bulbifera var. The use of micropropagation techniques for endangered plant genetic resources conservation was recognized late in the 70s[6]. Among the many documented medicinal folk uses, the plant is used to paste produced from the tubers to treat swelling and as a cure for snakebite and scorpion stings in Africa and Asia, and the bulbils are used to cure thyroid diseases and cancer in traditional Chinese medicine[18]–[20]. rotundata Poir. The ePub format uses eBook readers, which have several "ease of reading" features (D. bulbifera) belongs to the family Dioscoreaceae assigned to the order Dioscorales.It is commonly called air potato, air yam or bulbil-bearing yam. The absence of a stalk in the female flower of D. bulbifera is a distinctive feature of this taxon. Asian Pacific Journal of Tropical Biomedicine. Rhizoma Dioscorea bulbifera, the tuber of Dioscorea bulbifera L., has been used to treat various diseases. Similarly, the foliar epidermal anatomy of Dioscorea rotundata, Dioscorea cayenensis, Dioscorea dumetorum, and Dioscorea alata was reported to consist of anomocytic stomata only for the four species of Dioscorea studied[41]. *: P<0.05. Dioscorea belongs to the monocotyledons, family Dioscoreaceae, subfamily Dioscoreoideae. Herbalist Comparative qualitative and quantitative features of foliar epidermis of wild and micropropagated D. bulbifera are presented in Table 3. A combination of different diagnostic features (quantitative and microscopic parameters such as stomata and trichome types with sizes, shapes and sizes of epidermal cell, thickness of cell and cell inclusions) has been used for taxonomic distinction and recognition in the angiosperm family[11]–[15]. This is a good paper elucidating the importance of micro characters in the confirmation of the identity of both micro propagated and wild samples of D. bulbifera. A: Multiple shoots obtained from green house; B: Multiple shoots obtained from underground bulbil. Bulbifera.
