Effect of type of cuttings and growth regulators on rooting 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/litre(G1), IBA 7500 mg/litre (G2), NAA 5000 mg/litre (G3), NAA 7500 mg/litre (G4), IBA 5000 + NAA 5000 mg/litre (G5), IBA 5000 + NAA 7500 mg/litre (G6), IBA 7500 + NAA 5000 mg/litre (G7), IBA 7500 + NAA 7500 mg/litre (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/litre + NAA 5000 mg/litre were recorded significantly the highest growth parameter in terms of number of roots per cutting, length of root (cm), fresh and dry weight of root (g) and survival percentage of wax apple cutting.
