Germination characteristics of greater celandine (CHELIDONIUM MAJUS L.) Seeds

Аннотация

This article presents the results of research conducted on the germination of Greater Celandine (Chelidonium majus L.), one of the valuable medicinal plant species. It was found that under laboratory conditions, seed germination was high (91.4-93%) with an optimal germination temperature of 25-30°C. Field germination, however, was relatively low (17.7-24.5%), influenced by the seeds' anatomical structure and variable environmental conditions. Keywords: Seed, germination, embryo, seed coat, germination temperature, dicotyledonous nutlet, environmental factors, sowing periods. by studying its biological, morphological, and Introduction: Developing the pharmaceutical industry physiological characteristics. is one of Uzbekistan's priorities. This development requires establishing industrial plantations of medicinal METHODS plants and expanding their assortment. Many The germination of Greater Celandine seeds was medicinal plant species are representatives of wild studied under laboratory and field conditions. flora, with relatively little known about their ecological Laboratory germination was evaluated using standard and biological characteristics. This lack of knowledge seed science methods (Kuleshov, 1963; Leurda & hinders their cultivation and plantation development. Belskykh, 1974; International Seed Testing Rules, Thus, the study of biological features is necessary for 1984). Seeds were germinated in Petri dishes at scientifically based cultivation. different temperatures (20-22°C and 25-30°C) on filter Greater Celandine is a valuable medicinal plant not paper or river sand. Field germination was assessed by recorded in Uzbekistan's natural flora. Its extracts are sowing 100 seeds in January, February, and March, and used to treat liver, gallbladder, and skin diseases counting emerged seedlings. Data were statistically (Kholmatov, Qosimov, 1994). This study used seed analyzed using the methods of B.A. Dospekhov (1979). samples of Greater Celandine from Germany (first-
