Pengaruh Pemberian Casein Hydrolysate dan BAP terhadap Pertumbuhan Pisang Barangan Merah (Musa acuminata Linn.) secara In Vitro

Abstract

This study aims to determine the effect of Casein hydrolysate concentration and BAP on the growth of red barangan banana in vitro. This research was conducted at the Laboratory of Plant Biotechnology, Faculty of Agriculture, University of North Sumatra in November 2024 - February 2025. This study used a complete randomized design (CRD) method with two factorials. The first factor is the concentration of Casein hydrolysate (C): C0 (0 mg/l), C1 (300 mg/l), and C2 (600 mg/l). The second factor is the concentration of Benzyl Amino Purine (BAP): B0: (0 mg/l), B1: (2.5 mg/l), and B2: (5 mg/l). The parameters observed in this study include, percentage of living explants (%), age of leaflets, number of shoots, length of shoots, number of roots, and root length. The results showed that the combination of Casein hydrolysate and BAP significantly affected the root length parameter. The best treatment for root length was obtained from the combination of Casein hydrolysate 600 mg/l with BAP 2.5 mg/l.
