Abstract


This study aims to determine the effect of the interaction of the duration of immersion in auxin growth regulators and the origin of the cutting material and to obtain the best soaking time and origin of the cutting material for the growth of pepper cutting. The research was conducted at the Experimental Garden at the Faculty of Agriculture, Riau University from June to August 2019. This research is a factorial experiment arranged according to a completely randomized design consisting of two treatment factors. The first factor was the immersion time in auxin, which consisted of 1 hour, 2 hours, 3 hours, 4 hours. The second factor is the origin of the cutting material which consists of a base and a middle part. The data obtained from the research results were analyzed statistically using analysis of variance then followed by the BNJ test at the 5% level. The results showed that the interaction of the duration of immersion in the auxin growth regulator for 3 hours and the origin of the middle cuttings resulted in the highest vegetative growth in pepper cuttings. The length of soaking the cuttings in auxin growth regulating agent for 3 hours significantly increased the highest vegetative growth in pepper cuttings. The origin of the middle cuttings produced the highest vegetative growth compared to the origin of the base cuttings in pepper cuttings.
