chitosan as a soil amendment might also result from its direct effect on plant nutrient status and metabolism, and photosynthesis. Soil-applied chitosan increased the content of nitrogen, phosphorus, potassium, total sugars, and soluble proteins as well as

. Mitigating the inhibition of P n under high plant density probably occurs in only cases in which stomatal closure resulting from high VDP affects a limiting factor of photosynthesis before other factors. Fig. 6. Effects of vapor-pressure deficit (VPD) near

plant photosynthesis and marketability of the crop ( Franco et al., 2006 ). In some cases, stomatal conductance ( g S ) may not fully recover after periods of sustained or periodic water stress or previously stressed plants may acclimate through

effects such as reduced net photosynthesis and yield or leaf abscission ( Durner, 2013 ; Vu et al., 2001 ). The effect of water stress on the decrease in photosynthetic activity has been primarily attributed to stomata closure and reduced transpiration

Water is a limited resource worldwide. Water deficits often result in a decrease of P n , which can influence vegetative growth, yield, and fruit quality in fruit trees. The response of photosynthesis to water stress is correlated with stress

In the terrestrial ecosystem, carbon is added to plants through fixing of atmospheric CO 2 by the process of photosynthesis ( A n ), which can be defined as an oxidation-reduction reaction activated through light absorbed by chlorophyll, resulting
