Stomata and transpiration of droopy potatoes.
A diploid potato (Solanum tuberosum) mutant called droopy wilts easily. Excised leaves of the mutant lost weight, and hence water, more rapidly and had many more open stomata than leaves of a normal sibling. Further, the stomata of abnormal plants remained open in wilted leaves. When the stomata of the abnormal mutant were closed by a chemical spray, its excised leaves lost water no more rapidl...
متن کاملThe effect of simulated dust storm on wood development and leaf stomata in Quercus brantii L
Dust storms are increasingly threatening the forest ecosystem in Western Iran. Due to its coverage of vast area of Zagros forest, the Quercus brantii is at the front line of the attack. Most tree deaths in this forest are from this species. This study aims to investigate the effect of simulated dust on wood development and leaf stomata from seedlings of Persian oak. The oak seedlings were...
متن کاملFluorometric Measurement of Individual Stomata Activity and Transpiration via a “Brush-on”, Water-Responsive Polymer
Much of atmospheric water originates from transpiration, the process by which plants release H2O from pores, known as stomata, that simultaneously intake CO2 for photosynthesis. Controlling stomatal aperture can regulate the extent of water transport in response to dynamic environmental factors including osmotic stress, temperature, light, and wind. While larger leaf regions are often examined,...
متن کاملEffect of Chemical Control of Stomata on Transpiration of Intact Plants.
In the preceding communication' it was shown that phenylmercuric acetate sprayed upon detached leaves brings about closure of the stomata and thereby diminishes the diffusion of water from the leaves and of CO2 into the leaves. In 9 out of 11 experiments, induced closure of stomata reduced transpiration relatively more than CO2 assimilation as predicted from diffusion theory. This work led to e...
متن کاملSpinacia oleracea L. leaf stomata harboring Cryptosporidium parvum oocysts: a potential threat to food safety.
Cryptosporidium parvum is a cosmopolitan microscopic protozoan parasite that causes severe diarrheal disease (cryptosporidiosis) in mammals, including humans and livestock. There is growing evidence of Cryptosporidium persistence in fresh produce that may result in food-borne infection, including sporadic cases as well as outbreaks. However, drinking and recreational waters are still considered...
