“…Stomatal opening and decrease in stomatal resistance, which implies the reciprocal of stomatal conductance, were observed under high temperatures, allowing the plants to avoid heat stress (Homma et al, 1999;Reynolds-Henne et al, 2010). In contrast, increasing temperature did not have a significant impact on stomatal conductance (Greer, 2012;Li et al, 2012). Seversike et al (2013) showed that the slope of transpiration response to VPD, which somewhat corresponded to canopy conductance, decreased when the VPD increased above 1.9 kPa at 25℃ at the whole plant level in soybean.…”

This study aimed to investigate the effects of increasing temperature on the transpiration rate and canopy conductance of soybean grown in temperature gradient chambers under drought and wet conditions. The heat balance method was used to measure the transpiration rate from sap flow; additionally, canopy conductance was continuously estimated from the transpiration rate and vapor pressure deficit (VPD). An increase of 3℃ in temperature resulted in an increased transpiration rate but decreased canopy conductance. Further, the differences in canopy conductance observed at high and low temperature treatments were more remarkable during the morning than around noon. This suggested that there was concomitant increase in VPD with increasing temperature when solar radiation was low during the morning. Although the transpiration rate and canopy conductance decreased during drought conditions, the overall tendency of the response to the changes in temperature and VPD was similar to those in the well-watered condition. The partial correlation coefficients between canopy conductance and VPD were negative when the temperature effect was held constant. However, those between canopy conductance and temperature showed opposite trends in the two years of study-negative in 2011 but positive in 2012. These results suggest that the decrease of canopy conductance in a high temperature treatment is more likely caused by increasing VPD than by increasing temperature itself.

“…This is because increasing temperature simultaneously increases VPD, making it difficult to differentiate between the effects of high temperature and those of VPD (Weber et al, 1985;Greer, 2012;Li et al, 2012).…”

“…Those figures show that the correlation of both stomatal conductance and transpiration rate that has a close relationship with photosynthetic rate with successively r 2 values are 0.89 and 0.88 was obtained; it indicates that at photosynthetic rate was seemingly controlled by stomatal conductance and transpiration rate. Therefore it can be said clearly also, that all changes in photosynthesis were highly correlated with transpiration and stomatal conductance [17]. Furthermore, it is explained in Stomatal conductance of CO 2 before watering in the week eighth, the interaction between varieties with water supply significantly (p < 0,001) where a stomatal conductance will decrease due to lack of water and there is a signifficant effect in each watered as well as varieties.…”

In some rice dominated tropical regions, such as in Indonesia, soybeans are an increasingly important dry season crop which are often exposed to periods of drought stress. The morphological and physiological responses, which could lead to some tolerance to water stress, may vary between varieties. By better understanding the plant response to drought stress and finding if these responses vary between varieties better dry season production could be achieved. An experiment was conducted to compare the response of four varieties of soybean (glycine max (l.) Meer.) to five watering regimes, with the objective of determining the response of common soybean varieies across a wide range of water supply. Plant response to water supply was measured using gas exchange measurement with the rate of photo synthesis decreasing progressively from well watered to dry conditions across the four varieties. A correlation of stomatal conductance and transpiration rate has a close relationship with photosynthetic rate, where stomatal conductance of Burangrang variety has higher value than other varieties. Varieties Burangrang and Argomulyo stomatal conductances are higher value than those of Anjasmoro and Grobogan varieties. In a deficit of water condition, the Argomulyo varieties have a higher value of transpiration efficiency and significantly different than the other three varieties. The transpiration efficiency significantly declined for treatments watered once every two or three weeks. The transpiration efficiency values of Agromulyo and Burangrang varieties were significantly higher than another varieties.

“…Some commercially irrigated plants, such as grape vines, can double their transpiration rates as ambient temperatures increase from 20 o C to 40 o C and can thus lower their leaf temperatures by several Centigrade degrees (see, for example, Greer 2012). The extent to which mature eucalypts can do this under irrigation regimes that are probably less than those used for commercial agricultural production is not known.…”

Modelling leaf photosynthetic and transpiration temperature-dependent responses in Vitis vinifera cv. Semillon grapevines growing in hot, irrigated vineyard conditions

Abstract: Grapevines growing in Australia suffer from high temperatures which have major effects on photosynthesis and transpiration. To learn more, gas exchange was measured over several seasons and then modelled across temperatures from 20 to 45°C and validated with independent data.
