Evolution of the Stomatal Regulation of Plant Water Content[OPEN]
نویسندگان
چکیده
Terrestrial productivity today is regulated by stomatal movements, but this has only been the case since “stomatophytes” became dominant on the land 390 million years ago. In this review,we examine evidence for the functionof early stomata, foundonor near the reproductive structures of bryophyte-like fossils, and consider how this function may have changed through time as vascular plants evolved and diversified. We explore the controversial insights that have come from observing natural variation, rather than genetic manipulation, as a primary tool for understanding the function of the stomatal valve system.

To reduce transpiration and increase water use efficiency of olive trees in Ahvaz, the antitranspirant effects of of three levels of kaolin (0, 2.5% and 5%) on four varieties of olive (Mission, Conservolea, Keylet, Bledy) was carried out in a four-month period, with three replications. The results showed that Kaolin have a significant effect on plant water potential, leaf relative water content...

Accurate estimation of leaf stomatal conductance (gs) is important in predicting carbon andwater cycles of terrestrial ecosystem. To estimate gs on field-grown soybean and maize underwater-stressed condition accurately, a modified optimal stomatal conductance (OSCM) modelwas established based on the relationship between marginal water cost of carbon gain and soilwater content by introducing a w...

Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....
