The Effect of Cutting Stem and Plant Growth Regulator (PGR) on Chaya Plant

Abstract

Chaya (Cnidoscolus aconitifolius) Var. Picuda is an indigenous vegetable plant that is woody, drought resistant, and is generally propagated through vegetative propagation. Growth regulators greatly influence the growth of chaya plant cuttings. This research aims to determine the effect of giving natural plant growth regulator (PGR) to various sources of cutting material on the growth of chaya plants. This study used a two-factor randomized block design. The first factor is cutting stem i.e., top, middle and bottom stem and the second factor is growth regulators i.e. control, onion extract and coconut water extract. The research results showed that shallot extract had a positive influence on the emergence of shoots on chaya cuttings. Furthermore, the lower cutting planting material is either used as planting material for cuttings or for vegetative plant propagation. The bottom stem has sufficient food reserves and has an active bud growth point allowing the plant to grow and have a high growth success rate. The addition of onion extract can increase shoot and stem emergence, number of leaves, fresh weight of leaves.
