| Abstract: | Simple and useful evaluation indexes for the high temperature stability of photosynthesis(HTSP) in different rice varieties was studied for screening and identifying germplasm resources and new variety breeding.The diurnal changes of photosynthesis were tested under high temperature both in natural and illuminating incubator conditions using CIRAS-I portable photosynthesis system.Meanwhile,the genetic characters of HTSP were analyzed using F2 population derived from Texianzhan,a worse HTSP variety,and Shuhu... |
