Abstract. Solichatun, Putri TA, Mudyantini W, Pitoyo A. 2022. Effect of seed priming using KCL on the growth and proline accumulation of paprika (Capsicum annuum) growing at different water availability. Asian J Trop Biotechnol 19: xxx. Paprika (Capsicum annuum L.) is a vegetable commodity that has high economic value. Paprika cultivation still faces problems related to drought conditions. One technique to increase plant resistance to drought stress is the seed priming technique. Seed priming treatment can use various solutions, including KCl. The purpose of this study was to determine the effect of seed priming with KCl solution on the growth of paprika and accumulation of proline. This research is an experimental, using a completely randomized design (CRD) with a combination of seed priming treatment and water availability. Seed priming treatment was variation of concentration of KCl solution of 10, 20, and 40 ppm. The treatment of variations in water availability was 100% field capacity (FC), 75% FC and 50% FC. The experiment using 3 replications. Seed priming treatment using KCL at various concentration (10, 20, and 40 ppm) significantly affected the growth of paprika (C. annuum) that grow on variations in water availability. Seed priming treatment using KCl can increase the resistance of paprika plants to moderate drought conditions. Paprika resistance to drought is characterized by accumulation of proline and regulation of root to shoot ratio.
