Studying The Viability Of A Wild Coriander Species (bifora Radians M. Bieb.)

The studies used cenopopulations of the Bifora radians M. Bieb. from various ecological conditions of the Republic � Ordubad cenopopulation (SP1), Lerik cenopopulation (SP2), Ganja cenopopulation (SP3), Shabran cenopopulation (SP4), Guba cenopopulation (SP5). In the course of the study, the modified method of V.A.Chadaeva was used. The intensity of germination of Bifora radians M. Bieb. seeds under natural reproduction conditions, the number of germinated seeds, the diameter of seeds in the population, the number of plants per m2, the number of seeds per m2, the number of seeds per plant, the total number of seeds, as well as the indicators of seed yield were studied. A comparative analysis of the indicators of long-term studies was carried out. The role of other factors influencing the survival of the species was also investigated. In the life strategy of Bifora radians M. Bieb. heterospermia and the formation of a large number of seeds of different quality come to the fore. Such seeds do not ripen synchronously, and germinate at different times. Most dormant seeds germinate in the spring. Depending on the water-temperature regime and different seed quality, seed germination was observed in the subsequent periods after the first shoots, which ensured survival in conditions of environmental variability. The dormancy period of plants seeds of the genus Bifora radians M. Bieb. lasts more than a year. Depending on the cenopopulation, the seed germination rate varied within 78,0-88,0%. Being large, wild coriander seeds had a high germination rate. Environmental conditions seriously affect the dynamics of plant development, their seed productivity increases, and they become resistant to interspecific competition. Insects that feed on seeds have a strong effect on plants, causing them to spread and stay in new territories for a long time. Biological and anthropogenic pressure plays a key role in regulating the number of plants in the area. Interspecific interaction does not play a big role here. Thus, under favorable conditions, the development of wild coriander plants accelerates, the plants have a high habit. From the point of view of ecological strategy, wild coriander plants have a patient viability in phytocenoses.
