Abstract

Dendrobium is the epiphytic orchid and high demand because of its long-lasting freshness, color variants, shape, and high productivity. The addition of organic complex Coconut Water (CW) to the in vitro media such as MS and VW because in general organic complex compounds are sources of sugars, vitamins, growth regulators, and amino acids. The purpose of this study was to obtain the best media for plantlet regeneration from PLBs of Dendrobium orchids var. JTWO and var. Kumala Agrihorti. This study used a Completely Randomized Design consisting of two factors with five replications. The combination of  planting media with the addition of coconut water was consist of 10 levels, ½ MS+0 ml/l CW, ½ MS+75 ml/l CW, ½ MS+100 ml/l CW, ½ MS+125 ml/l CW, ½ MS+150 ml/l CW, VW+0 ml/l CW, VW+75 ml/l CW, VW+100 ml/l CW, VW+125 ml/l CW and VW+150 ml/l CW. The results showed that the variety treatment gave a significant effect on the percentage of PLBs regeneration, the number of shoots, and the increase in plantlet height. The treatment of media gave a significant effect on the percentage of PLBs regeneration, percentage of PLBs life, the number of leaves, and the number of roots. The interaction between treatments significantly affects the percentage of PLBs regeneration.

Abstract

This research was aimed to know the effect of concentration treatment young coconut water on the growth and result of three Varieties Land Water Spinach. This research was conducted from May until June 2021 at Cikupa, Tangerang. This Research used Randomized Completely Block Design (RCBD), consisted two factors. The first factor was concentration of young coconut water with four level, namely: K0 = control without concentration young coconut water, K1 = 225 ml concentration of young coconut water, K2 = 250 ml concentration of young coconut water, and K3 = 275 ml concentration of young coconut water. The second factor was Varieties of land water spinach with three level, namely: V1= Bangkok, V2= Bisi, V3=Bika. Each treatments repeated 3 times. Parameters observed were plant height, number of leaves, fresh weight per plant, and root long. The result showed that, 275 ml concentration of young coconut water gave the best result on the parameter plant height in 7 Day After Planting (DAP): 9,69 cm; 14 DAP (19,99 cm); 21 DAP (33,20 cm); and 28 DAP (47,03). The treatment of three Varieties, Bangkok gave the best result on number of leaves in 7 DAP (2,00 sheets). There were interaction between the treatment of concentration young coconut water and Varieties of land water spinach on the  parameter plant height (28 DAP) and number of leaves (7 DAP). Key Words: Young Coconut Water, Varieties of land water Spinach
