摘　　要：The article is devoted to the study of bioecological features of Ipomoea nil in the conditions of the Tashkent Botanical Garden. Seeds were sown 8 - 10 cm deep in the first decade of April. Seed germination averaged 85% - 90%. The beginning of vegetation and leaf regrowth in Tashkent is observed in the second decade of April. The flowering phase was observed in the first decade of August and fruiting was noted in the first decade of September. Biometric indicators of the plant during the generative phase were revealed as follows: plant height 2.95 ± 0.22 m, generative shoot length 2.62 ± 0.24 m, number of leaves 46.5 ± 3.59 pcs., leaf length 10.11 ± 0.49 cm, root length 19.85 ± 0.88 cm, number of flowers 42.8 ± 2.37 pcs., flower diameter 4.82 ± 0.28 cm. Potential seed productivity (PSP) of the plant was noted 13.5 ± 0.5 pcs., real seed productivity (RSP) was 10.8 ± 0.44 pcs. And in turn, the seed productivity coefficient (SPC) amounted to 80.0% ± 1.31%. The primary results prove, according to the success of Ipomoea nil introduction, the noted indicators in Tashkent conditions.The article is devoted to the study of bioecological features of Ipomoea nil in the conditions of the Tashkent Botanical Garden.
