stomatal उदाहरण वाक्य

In addition to weather uncertainties, the Penman Monteith equation is sensitive to vegetation specific parameters, e . g . stomatal resistance or conductance.
Feeding normally occurs via stylet penetration of epidermal cells, but sometimes nematodes can enter through stomatal openings and feed from within the mesophyll cell layer.
Both of these factors influence the rate of bulk flow of water moving from the roots to the stomatal pores in the leaves via the xylem.
This instrument can give a relative measure of stomatal conductance in a few seconds, making it possible to identify physiologically superior genotypes from within bulks.
Stomatal conductance in white spruce seedlings declined generally from more sheltered to more exposed environments, correlating best with increased vapor pressure deficit ( VPD ).

ABA then translocates to the leaves, where it rapidly alters the osmotic potential of stomatal guard cells, causing them to shrink and stomata to close.
The foliage sprays are green above and green marked with whitish stomatal bands below; they are strongly aromatic, with a scent reminiscent of pineapple when crushed.
Moisture stress also has an effect on stomatal openings of a plant, mainly causing a closure in stomata as to reduce the amount of carbon dioxide assimilation.
The leaves are linear, long and wide, glossy dark green above, and with two white stomatal bands below; the leaf margins are slightly revolute.
The bottom of the leaf is glaucous with two broad and clearly visible stomatal bands, while the top is a shiny green to yellow-green in colour.
