摘要: The photosynthesis of Tidestromia oblongifolia (Amranthaceae) is remarkably well adapted to operate at the very high summer temperatures native habitat on floor Death Valley. photosynthetic rate was and reached its daily maximum when light intensity noon leaf 460 degrees 50 C which occurred this time. At sunlight decreased markedly temperature experimentally reduced below 44 C. optimum 47 essentially directly proportional up full sunlight.
