Abstract:

This paper reviewed some recent research progress in effects of different altitude on rice yield and quality in China. The results showed that with the increase of altitude, accumulated temperature required for the growth of rice decreased, the whole growth period of rice extended, the tillering stage postponed and the seed- setting rate reduced. Also, yield, effective panicles and grains per spike decreased after increasing with increasing altitude. In terms of quality of rice, altitude had greater effects on the milled rice rate and chalkiness. The milled rice rate had significant increase and chalky grain rate had a clear downward trend with the increase of altitude. There was large difference in the studies between altitude and cooking and eating qualities of rice, which needed to be further studied in the future.
