Abstract

Aim. To explain the rice seeds longevity from the point of view of genetic control of their formation under climate change. Methods. Analysis of the current state of scientific research on genetic control of seed formation, laboratory studies of rice seed germination, monitoring of meteorological conditions of seed formation in different years of reproduction, results statistical processing. Results. Rice seed longevity of different reproduction years under conditions of formation in climate change context was analysed. Lower longevityity of experimental seeds under formation conditions with higher precipitation was found. Influence of genetic control, transcription factors on seed embryo formation and reserve nutrients in different climatic conditions is discussed. Conclusions. Rice seed formation conditions during higher precipitation had a negative impact on seed longevity even under optimal medium-term storage conditions. Additional research is needed to prove the change in transcriptional regulation of certain synthesis of necessary for seed formation and development under these conditions substances.
