PENGARUH KONSENTRASI ZAT PENGATUR TUMBUH 2,4-D DAN BAP SERTA JENIS MEDIA PADA INDUKSI KALUS EKSPLAN DAUN SEMANGKA
Tissue culture is a plant propagation method that has the potential to solve the problems of conventional watermelon seedling propagation. This study aims to determine effects of growth regulators 2,4-D and BAP and types of media on the callus induction of watermelon leaf explant. The study was conducted at the Tissue Culture Laboratory, Faculty of Agriculture, Sriwijaya University, using a Complete Randomized Factorial Design (CRFD) with two factors: media type (100% MS medium and 50% MS medium and 50% coconut water) and growth regulator concentration (1 ppm 2,4-D and 1 ppm BAP, 2 ppm 2,4-D and 1 ppm BAP, and 3 ppm 2,4-D and 1 ppm BAP). The results showed that 100% MS medium was able to increase the percentage of explants forming callus by 83.33%, increase explant mass by 259.5 g, and increase the percentage of live explants to 100%. A concentration of 3 ppm 2,4-D and 1 ppm BAP growth regulators was able to accelerate the time for explants to form callus to 14.35 days after inoculation. The 50% MS medium and 50% coconut water mixture had an effect on the contamination rate of 26.66%. Keywords: Coconut water, watermelon leaves, callus, Murashige and Skoog
