ОНТОМОРФОГЕНЕЗ РОСЛИН ВИДІВ РОДУ AMARANTHUS L. В УМОВАХ КРЕМЕНЕЦЬКОГО БОТАНІЧНОГО САДУ

One of the important areas modern science is conservation biodiversity, including plant diversity, which occurs through introduction. Among introducers are species genus Amaranthus L., promising for use in many sectors economy. Species well known crop production, and fodder becoming more widespread as food, medicinal, technical plants. Due to high productive potential sagebrush plants multifunctional value raw materials, there a problem production crops production. This raises number questions related study features ontogenesis.
 The article presents results observations introduced L. Kremenets Botanical Garden. Purpose – establish THE ontomorphogenesis peculiarities conditions introduction subject investigation Amaranthus. Investigations were conducted 2019–2021 years on plot department medicinal new developmental state was allocated according descriptions methodology ontogenesis T. A. Rabotnov.
 Peculiarities ten collection specimens following: caudatus cv. Carmine, Zolotystyi, Kremovyi ranniy, Kharkyvskyi, Rushnychok, cruentus Bulavovydnyi, hybridus Atlant, paniculatus leucospermus S.Wats. general botanical description given, analysis biometric parameters shoots given. During genus, undergo different age changes, characterized by structural biological features. A full cycle ontognesis takes one year. It found that culture have four periods: latent, pregenerative, generative, postgenerative states: seeds, sprouts, juvenile, immature, virginal, dying. generative period lasts longest, beginning second or third decade July lasting until first October. established duration vegetation Garden 130–137 days. shortest phase budding 13–22 longest vegetative 42–58 days flowering 22–33 all phases development depends characteristics weather conditions.
