Effect of type of cuttings and growth regulators on sprouting and growth parameters of wax apple (Syzygium samarangense L.)

Abstract

The study was conducted during 2015-16 at Agriculture Experimental Station (AES), Navsari Agricultural University, Paria, Dist- Valsad. An experiment comprised with two factors (1) Types of cutting [Hardwood cutting (P1) and Semi-hardwood cutting (P2)] and (2) Growth regulators [IBA 5000 mg/lit.(G1), IBA 7500 mg/lit. (G2), NAA 5000 mg/lit. (G3), NAA 7500 mg/lit. (G4), IBA 5000 + NAA 5000 mg/lit. (G5), IBA 5000 + NAA 7500 mg/lit. (G6), IBA 7500 + NAA 5000 mg/lit. (G7), IBA 7500 + NAA 7500 mg/lit. (G8) and Control (G9)] in Completely Randomized Design with Factorial Concept and repeated thrice under Net house conditions. Results showed that among the different cutting types and growth regulators, hardwood cutting and IBA 5000 mg/lit. + NAA 5000 mg/lit. were individually as well as in their combination found to be the most beneficial for early sprouting. Similar trend was observed on the growth parameters such as number of shoots, leaves and leaf area, length and diameter of longest shoot, fresh and dry weight of plant and survival percentage.
