“…As shown here and in previous studies, water deficit decreases photosynthesis (Kaiser 1987;Panković et al 1999;Li et al 2007). Drought has been shown to limit photosynthesis via stomatal closure and metabolic impairment (Flexas et al 2002;Bota et al 2004;Denaxa et al 2012). Under well-watered conditions, yeast treatment had a lower A during the whole period of investigation than the controls (Figure 1(A)), together with a reduction in E and g s (Figures 2(A) and 3(A)).…”

This study investigated whether the exogenous application of yeast (Saccharomyces cerevisiae) could alleviate the adverse effects of drought on rice (Shanyou 63). Yeast was sprayed on leaves at 10 9 colony-forming units (cfu) ml 21 after drought every week. The drought period lasted 120 days. Under well-watered conditions, application of yeast significantly reduced net photosynthetic rate (A) and transpiration rate (E), together with a reduction in stomatal conductance (g s ) compared with the controls, and yeast did not inhibit plant growth. Under drought conditions, application of yeast increased E, but had no effect on A on days 30, 44, 58 and 72 compared with the drought without yeast. Under drought conditions, yeast application increased the seed set rate, 1000-grain weight, grain yield, harvest index and grain: straw compared with the drought without yeast. Yeast did not have a significantly promotive effect on WUE leaf (A/E) under either well-watered or drought conditions. Irrigation water use efficiency (IWUE) values were significantly influenced by yeast. The greatest IWUE was observed in yeast treatment under drought conditions (3.1 mg g 21 ). This study indicated that yeast can alleviate the negative effects of drought stress by improving some photosynthetic attributes and yield in rice.

“…In practice, the reduction in g s determined by kaolin, as demonstrated in other species (De Boer et al, 1983;Schroeder and Johnson, 2004;Angbabu et al, 2007), would help to save water, which would benefit more crops with limited water supplies and, therefore, over time would maintain a higher assimilation rate than crops without kaolin, as also observed by Denaxa et al (2012) on olive trees.…”

“…Application of 10% processed kaolin particle film on papaya leaves showed higher light reflection and lowered the leaf temperatures during the peak hot period from 12 pm and 2 pm (Campostrini et al, 2010). Kaolin clay particles had a significant positive effect on olive leaf water content, succulence, leaf tissue density and leaf temperature under both drought and well irrigated conditions (Denaxa et al, 2012).…”

“…Campostrini et al (2010) applied 10% foliar processed-kaolin particle film over 'Golden' papaya leaves and found that it did not affect net CO 2 assimilation rates, stomatal conductance and transpiration; although the light reflection was higher and the temperature on the leaves was significantly lowered in the plants that received the particle film coating. Denaxa et al (2012) applied glycine betaine and kaolin clay particles to drought stressed olive trees, which resulted in increased CO 2 assimilation rates compared to control. Furthermore, kaolin clay particles treated leaves exhibited high diurnal CO 2 assimilation rates under drought conditions.…”
