Pengaruh Pemberian IBA dan Asal Stek Terhadap Pertumbuhan Vegetatif Kumis Kucing

Abstract

This study was conducted to determine the effect of administration of IBA on the origin of cuttings material on vegetative growth of plant cat whiskers. This research was carried out in the Trunojoyo Madura University Experimental Field. The time of the study was conducted in January - April 2016. This study used a Completely Randomized Design (CRD) consisting of 2 treatments, namely the origin of the cuttings and the IBA concentration. The origin of the cuttings section (A), namely A1: the base cuttings, A2: middle cuttings, and A3: cutting cuttings. The concentration of IBA (B), namely B0: 0 ppm, B1: 25 ppm, B2: 50 ppm, and B3: 100 ppm. The results showed that the origin of the cuttings section of cat whiskers and administration of IBA had a significant effect on the variable number of shoots at ages 8 to 14 (MST), shoot length at 10 to 14 (MST), leaf and stem wet weight, and leaf dry weight. root, but did not significantly affect the variables when buds appeared, the longest roots, root wet weight, and stem dry weight. The middle stem cuttings with IBA 100 ppm give the highest value for the variable shoot length. The middle stem cuttings with IBA 25 ppm gave the highest value to the variables of wet, leaf, stem, root, and dry weight of leaves, stems, and roots.
