Оntogenetic and embryological development’s features of Nelumbo komarovii Grossh. (Nelumbonaceae)
Year: 2025, Issue: LXXIII, Pages: 227 - 244
The collective work of the authors shows the uniqueness of the ontomorphogenesis and generative sphere of the N. komarovii, the rarest species in the south of the Russian Far East. Two phases of N. komarovii embryo development are identified: blastomerization and embryonic phase. During initial year of life in this species, after a latent period, the phase of the primary (main) shoot is successively replaced; systems of “main shoot” and anchorage shoots; curtains; tuberous structure. In the next year plant moved across phase’s vegetative, vegetative-generative shoots and tuberous structure. The phases of morphogenesis correlate with periods of ontogenesis and age-related stages of individuals. The annual and seasonal dynamics of the N. komarovii population in the south of Primorsky Krai conditions are considered. It is difficult to trace the end of N. komarovii ontogenesis due to the fact that the vegetative mobile plants have the high degree of rejuvenation offspring and vegetative propagation. The comparative cross-species discussion into genus Nelumbo is given.
