CABRERA JOVA, Manuel et al. Field evaluation of yam plants (Dioscorea alata L.) obtained from microtubers produced in a temporary immersion system. Rev. colomb. biotecnol [online]. 2010, vol.12, n.1, pp.47-56. ISSN 0123-3475.

Microtubers in some plant species represent an important alternative crop-planting material. The present work involved field work for evaluating the morphoagronomic response of plants obtained from yam microtubers produced in a temporary immersion system (TIS). Three categories of microtuber were planted as experimental variants; they were classified by fresh mass (1 - 0.5 to 0.9 g, 2 - from 1.0 to 2.9 g and 3 - equal toor greater than 3.0 g), previously in vitro-acclimated plants and tuber crowns. The effect of microtuber fresh weight on their sprouting, survival and later development of the plants derived from them in the field were evaluated. The highest sprouting (91.30%) and plant survival percentages (96.50%) and the best response in quantitative traits evaluated in the field were obtained with yam microtubers having a fresh mass equal to or greater than 3.0 g. These results confirmed the importance of microtubers’ fresh weight for using them as plant material in direct planting in the field.
