Abstract: 4 different rice varieties were used to study the effects of photoperiods on source-sink relations during panicle initiation stage. It had been revealed that,under long-day treatments, sink organs developped slowly and heading date was delayed;the dry matter production and its partitioning to sink

Key words: Rice, Source-sink relations, Photoperiods
