Abstract
Kamajaya Durian (Durio zibethinus Murr.) is one of rare tropical fruit plants placed in Cimahi. The parent tree of Kamajaya durian is approx. 120 years old. As a landrace plant, it needs an effort to maintain its quality and quantity. This study was conducted to determine the effect of 2,4-D growth regulators and Kinetin to form callus on Kamajaya durian bud leaves in vitro. The research was conducted at the Plant Tissue Culture Laboratory of the Faculty of Agriculture, Universitas Padjadjaran, from October to December 2019. The research used factorial randomized block design in three replication and descriptive analysis method. The first factor was growth regulator 2,4-D consisted of 5 treatments i.e. 1 ppm, 2 ppm, 3 ppm, 4 ppm, and 5 ppm. While the second factor was Kinetin concentrations i.e. 0 ppm, 0.5 ppm, and 1 ppm. The results showed 2,4-D of 2 ppm, 3 ppm, 4 ppm, and 5 ppm as well as combination between Kinetin 0.5 ppm + 2,4-D 2 ppm, Kinetin 0.5 ppm + 2,4-D 5 ppm and Kinetin 1 ppm + 2,4-D 5 ppm gave an effect of bud leaves explant curled.
