In Vitro Propagation of Trichosanthus Dioica Roxb. for Nutritional Security
Satyajit Saurabh,Dinesh Prasad,Ambarish S. Vidyarthi 한국작물학회 2017 Journal of crop science and biotechnology Vol.20 No.2
The pointed gourd (Trichosanthes dioica Roxb.) is an important cucurbit reported for its medicinal value, therapeutic potential, and as a popular delicacy (especially in Indian cuisine). Being nutritive and desirous, it has potential to feed the nations and addresses their nutritional security and economic prosperity. The plant is usually vegetatively propagated and cultivated for fruits during summer and rainy seasons. The limited supply of planting material, limits cultivation and production. The present study was in anticipation for direct organogenesis, callus induction, and somatic embryo formation from leaf and node explants of T. dioica Roxb. In this study, the MS medium supplemented with 0.5 mg/L BA and 0.5 mg/L 2,4-D was found to be most efficient for callus induction, followed by 0.5 mg/L Kn and 0.5 mg/L 2,4-D. The embryogenic callus was developed by sub-culturing of node callus in the same media. The scanning electron microscopic (SEM) analysis revealed the presence of embryogenic cell clusters having globular embryos, which were found irresponsive to develop further. Through direct organogenesis, the node explants have responded to produce true-to-type plants for propagation. It was observed that MS supplemented with 1.0 mg/L BA was efficient for shoot proliferation, and 0.5 mg/L IAA was found more efficient for root development. Notably, the plant remains unexplored in its potential for improvement involving molecular breeding and tissue culture. These results may be effective to produce genetically stable plants on a large scale and aid the genetic improvement of pointed gourds.
