Stomatal and mesophyll limitations of photosynthesis in black spruce seedlings during multiple cycles of drought.

Container-grown black spruce (Picea mariana (Mill.) B.S.P.) seedlings were planted in trays containing a sand and peat mixture, and placed in a climate-controlled greenhouse. One group of seedlings was kept well-watered, and another group was subjected to three cycles of drought. Gas exchange analysis showed that mesophyll photosynthetic function was largely unimpaired by drought. In contrast, ...

Stomatal and Nonstomatal Components to Inhibition of Photosynthesis in Leaves of Capsicum annuum during Progressive Exposure to NaCl Salinity.

Young bell pepper (Capsicum annuum L.) plants grown in nutrient solution were gradually acclimated to 50, 100, or 150 moles per cubic meter NaCl, and photosynthetic rates of individual attached leaves were measured on several occasions during the salinization period at external CO(2) concentrations ranging from approximately 70 to 1900 micromoles per mole air. Net CO(2) assimilation (A) was plo...

Drought-inhibition of photosynthesis in C3 plants: stomatal and non-stomatal limitations revisited.

There is a long-standing controversy as to whether drought limits photosynthetic CO2 assimilation through stomatal closure or by metabolic impairment in C3 plants. Comparing results from different studies is difficult due to interspecific differences in the response of photosynthesis to leaf water potential and/or relative water content (RWC), the most commonly used parameters to assess the sev...

Effect of leaf water deficit on stomatal and nonstomatal regulation of net carbon dioxide assimilation.

The effect of leaf water deficit on net CO(2) assimilation was studied under two conditions: in one, the stomata were allowed to contribute to the regulation of CO(2) assimilation; in the other, air was forced through the leaf at a constant rate to overcome the effects of change in stomatal resistance accompanying changes in leaf water deficit. When the stomata were allowed to regulate the gase...
