PENGARUH MACAM ZAT PENGATUR TUMBUH DAN PANJANG STEK TERHADAP PERTUMBUHAN TUNAS ANGGUR (Vitis Vinifera, L.)

Abstract

The study aims to determine the effect of application of growth regulators and the length of cuttings on the growth of grape cuttings. The study was conducted in May 2015 to August 2015 in Maguwoharjo, Depok District, Sleman Regency, Yogyakarta. The study used an experimental method with a completely randomized design, with two factors. Factor I is a type of ZPT which consists of 4 types: Control, IAA, IBA and Rhizzatun. Factor II is the length of the cuttings consisting of 3 levels, namely 15 cm, 20 cm and 30 cm. The analysis data used analysis of variance. To find out the real difference used Duncan's multiple range test at the real level of 5%. The results showed that there was no combination between the application of growth regulators and the length of cuttings to the growth of wine cuttings. The length of cuttings influences the growth of grape cuttings, best 30 cm compared to 20 cm and 15 cm. Application of IAA, IBA and Rhizzatun does not affect the growth of cuttings.
