Abstract: "[Investigators] used a three-parameter, modified Arrhenius equation, originally developed for leaf respiration, to characterize A/T [CO2-assimilation/Temperature] curves of Date Palm and acclimation to elevated growth temperature and water deprivation." |
| Comments |
P.631 right column bottom paragraph: "Water deprivation decreased DW/FW of date palm leaves and depended on growth temperature. DW/FW of well-watered plants was less for plants grown at 35 °C than 20 °C. This pattern was reversed in water-deprived plants (Table 2)." P.632 right column bottom paragraph: "Increased growth temperature had only a minor effect on Topt [Optimum temperature of A [CO2-assimilation]], ranging from 29.5 ± 1.7 °C in 20 °C grown plants to 31.5 ± 0.6 °C in 35 °C grown plants (Fig. 4l p = 0.08, Table 3). Increased growth temperature increased Aopt [Peak rates of net photosynthesis at optimum temperature (=physiological capacity of A)] by c. 60% in well-watered plants, but only marginally increased Aopt in water-deprived plants (Fig. 4d). Effects of growth temperature and water deprivation were more pronounced for Agrowth [Net photosynthesis at growth temperature](Fig. 4h). Both increased growth temperature and water deprivation significantly increased Agrowth (Table 2). These effects resembled those of Rgrowth, such that the ratio of Agrowth/Rgrowth [Respiration at growth temperature] remained almost constant (see Supplementary Information Fig. S1)." |
