Abstract

The study presents the development of an innovative technology for propagating seedlings of local citrus varieties—lemon, orange, and mandarin—using the biopolymer-based preparation UZKHITAN. This preparation, a polymer mixture of chitin and carboxymethyl cellulose, was applied to citrus cuttings to enhance rooting efficiency under controlled conditions. Experimental results demonstrated that treatment with UZKHITAN significantly accelerated the rhizogenesis process and improved the rooting percentage of citrus cuttings compared to conventional stimulants. The highest rooting rates (91–94%) were observed in lemon cultivars F-1 Tashkent and F-2 Yubileiny, while orange and grapefruit–pomelo hybrids showed moderate rooting (34–37%), and mandarin cuttings exhibited the lowest rate (22%). The optimal treatment duration was found to be 5 minutes, resulting in callus formation on days 9–10 and complete rooting within 25–28 days. This method reduces the rooting period nearly by half compared to traditional heteroauxin treatment. The study concludes that encapsulating citrus cuttings in UZKHITAN prior to planting provides a highly effective, eco-friendly, and economically feasible propagation technology for citrus crops in Uzbekistan. This approach enables the year-round production of high-quality planting material, maintains varietal purity, and ensures early fruiting, thereby contributing to the development of intensive citrus cultivation and the achievement of the national agricultural goals outlined in the Strategy for the Development of New Uzbekistan (2022–2026).
