According to the fit coefficients between net photosynthetic rates and PAR under powerful radiation and high temperature conditions, the diurnal variation of photosynthesis could be divided into part fit model? fundamental fit model and complete fit model. The higher the fit coefficients between net photosynthetic rate and PAR were, the stronger the net photosynthesis adaptive abilities of flag leaf were under powerful radiation and high temperature conditions . Photosynthetic potential (product of net photosynthetic rates, the fit coefficients between photosynthetic rates and PAR, flag leaf area/stem, main stem number/hm 2) could be used to exactly forecast wheat photosynthetic potentiality . There were remarkable positive correlations between photosynthetic potentiality and wheat production or production potentiality. The correlation coefficients were 0.96, equally.Read More
