ROOTSTOCKS AND PLANT GROWTH REGULATOR TO PROMOTE GROWTH OF GRAPEVINE SEEDLING CV. PRABU BESTARI

Abstract

Good quality seedling is the key to achieve potential of production and quality of fruit. Cuttings-grafting is a propagation method applied to obtain good quality plants, ones that have strong roots and are resistant to disease. This study aimed to describe the effect of rootstocks and plant growth regulator in promoting growth of grapevine seedling cv. Prabu Bestari. The study was conducted in Tlekung Experimental Garden, East Java. It employed factorial Completely Randomized Design with 2 factors and 3 replications. The first factor was the rootstock variation that consisted of 3 levels, namely Banjarsari 30, Banjarsari 5, and Banjarsari 8. The second factor was plant growth regulator consisting of 5 levels, namely Rootone-F, Shallot Extract, Young Coconut Water, Java Turmeric Extract, and Control. The findings showed that Banjarsari 30 as rootstock and Rootone-F as growth regulator gave the best response in growth of grapevine seedling cv. Prabu Bestari.
