N2  - Leaf photosynthetic rates, loss of photosynthate 14C, sucrose concentrations and invertase activities were measured in three genotypes of Pennisetum growing at daylnight temperatures that ranged from 18/13 to 33/28&#176;C. Leaves at low temperature had low photosynthetic rates, exported 14C more slowly, retained a higher proportion of photosynthate 14C, had higher sucrose concentrations and aged (physiologically) more slowly than did leaves growing at higher temperatures. The genotype that retained most photosynthate in the source leaves was the most cold-intolerant whereas there was no correlation between photosynthetic rates and previously observed growth rates.
