The slower rate of stress development for Cabernet Sauvignon could be due to a number of factors including differences in soil type, vapor pressure deficits, temperature, age of the vines, root stock, depth of roots, and trellising systems.
During the 1997 dry season, the seasonal average daytime Bowen ratio increased from 0.7 to 4.1 which was associated with increase in air humidity deficit and temperature.
Shen et al [ 68] reported that OsClpD1 is induced by water deficit and temperature stress in vegetative tissues.
In the model, photosynthesis is restricted by frost, high vapor pressure deficit, suboptimal temperatures and soil water deficits.
Short-term undesirable conditions (e.g. moisture deficit, cold temperatures) generally reduce photosynthetic carbon supply while increasing soluble carbohydrate accumulation.
A number of common short-term stresses (e.g. water deficit, extreme temperatures, defoliation) reduce photosynthetic carbon supply [2], [3], [4], [5].
All three experiments had a control (no water deficit, 29°C day temperature), high day temperature (38°C), water deficit, and a combined high temperature and water-deficit treatment.
Thellungiella exhibits a significant innate capacity to tolerate water deficits, freezing temperatures, and high salinity [ 14, 15].
The functional roles of some representatives, like the dehydrins class and the rd29A, or the cold-regulated COR15B/15A and the low temperature-induced LTI30, may be related to responses to water deficit and low temperature, respectively [ 12].
Therefore, it is necessary to study and understand the effects of and interactions between water deficit and high temperature at flowering in rice.
