Growth response of morel berry (Physalis angulata) under different cutting types and plant growth regulators

Abstract

This research aims to find the right method and the best plant growth regulator to stimulate the propagation of morel berry plants so that the time used becomes more efficient. This research was carried out in May – October 2024 at Plant Laboratory 3, Lampung State Polytechnic.  This research was structured in a Completely Randomized Factorial Design consisting of 2 factors. The first factor is the types of cutting. The second factor is the type of plant growth regulator. The research stages include: preparation, preparation of planting material, preparation of planting media, planting and application of PGR, maintenance and observation.  Observation variables include growth percentage, number of shoots, and shoot length. Analysis of experimental data using analysis of variance followed by the HSD test at the 95% level. Based on this research, it can be concluded that the growth potential for propagating morel berry plants is better by using upper stem or shoot cuttings with a success percentage of 81%. There was no real interaction between the cutting material treatment and the type of PGR used. The best type of PGR is sprout extract. A more in-depth study is needed regarding the appropriate PGR concentration for each type of PGR.
