> In this study, we assayed the response of rice flowering time to N supplies and identified a N-mediated floral regulatory gene functioning in both short- and long-day conditions. Rice form a fibrous root system consisting of seminal, nodal and lateral roots. The panicle is borne on the uppermost internode of the culm.Thepanicles bear spikelets, most of which develop into grains. 7. Classification. The first spikelet to flower is generally in the middle third of the spike and usually near the upper part of this section; the flowering progresses rather rapidly upwards, downwards a little slower. �!�0��@�t The parent lines (CMS & Restorer) of the rice Chapman & Hall, New York.
