Potato tuber (Solanum tuberosum L.) formation due to the application of different concentrations of coconut water in in-vitro

Abstract

This study apply coconut water to support the process of formation of potato tubers in vitro. The study was conducted at the laboratory of tissue culture, Experimental Garden of Vegetable Research Center, Berastagi, North Sumatera. The experiment used Completely Randomized Design with single treatment factor, the coconut water concentration of 0; 75; 150 and 225 ml L−1. The results show that the application of coconut water provides a significant effect on the number, diameter and fresh weight of potato micro tubers, but the effect is not significant at the time of potato micro tuber formation. The application concentration of coconut water 225 mL L−1 affected the potato micro tuber formation in in vitro.

Effect of Coconut Water and GA3 Concentrations on in vitro Clonal Propagation of Potato Cultivars from Nepal

“…In potato tissue culture, GA3 is the most frequently used hormone that promotes shoot elongation and multiplication of the in vitro plantlets [10]. However, the high cost and limited availability of such hormones have prompted researchers to explore alternative growth-promoting substances, such as coconut water (CW), which has shown potential as a natural substitute [11,12]. In light of these key components, this study was conducted with an aim to explore the advantages of the CW over commercially available plant growth regulators, virus elimination, and growth performance in different solidifying agents (agar vs. Clarigel) were examined in two varieties of potato; Janak Dev and Cardinal as these varieties are the most common ones for the hilly regions of Nepal.…”
