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.

 
Keywords: Altitude, Rice, Yield, Quality.
