were determined over a wide range from 10 to 45 C. Leaf photosynthesis measurements
were performed at the Agriculture Faculty, Kasetsart University, Thailand and in a growth
chamber at French National Institute for Agricultural Research (INRA-PIAF), Clermont-
Ferrand, France. Photosynthetic rate of RRIM600 stayed almost constant between 23 to 37
C, and decreased distinctly with increasing temperature from 38 to 45 C. Photosynthetic rate …
