Micro Propagation in Advanced Vegetable Production: A Review

Abstract

Micro propagation is a fast method of plant propagation that has a great potential to develop high quality as well as disease-free plants. Advancements in this field have led to the development of several techniques for rapid multiplication and improvement of a wide range of horticultural crops and their production systems. Micro propagation includes three types of vegetative propagation, 1) somatic embryogenesis, 2) adventitious shoot production and 3) axillary shoot production, which provide excellent opportunities for successful vegetable crops production. In Capsicum genera, annuum-chinense- frutescens complex have been made with white flowers and small yellow seeds. A number of experiments have also been done to demonstrate the influence of hypocotyl explant orientation on shoot bud induction in Capsicum spp. Sweet potato cuttings when grown in vitro with Florialite gives greater percentage of survival. Similarly, in vitro layering of gourds; a modification in micro propagation methods become more advantageous as it produces single shoot rather than multiple shoots. Likewise, an immobilized culture system of obtaining torpedo-stage embryos of carrots of uniform size and higher tuber yield with rapid multiplication rate for potato were also introduced by micro propagation techniques.
