Distribution of ~(14)C-assimilates from the panicle and rice leaves during the grain filling

摘要

Change of sink-source relations during rice grains formation and filling period was studied. It is established that after anthesis the panicle takes part in formation of the temporary reserves of assimilates in the stem by means of the export of some part of photoassimilates into it. Possible phytohormones participation in the regulation of the photoasaimilates flows is discussed.
