Ozone deposition to an orange orchard: Partitioning between stomatal and non-stomatal sinks.
Orange trees are widely cultivated in regions with high concentrations of tropospheric ozone. Citrus absorb ozone through their stomata and emit volatile organic compounds (VOC), which, together with soil emissions of NO, contribute to non-stomatal ozone removal. In a Valencia orange orchard in Exeter, California, we used fast sensors and eddy covariance to characterize water and ozone fluxes. ...
متن کاملEffects of lithium on stomatal regulation.
Recent findings indicate that lithium belongs to the group of rather exclusive agents which affect the period of circadian clocks: The period of the cir cadian petal movements of Kalanchoe is increased by about 2 hours in 5 m M LiCl 2. In the present paper we will report an action of lithium on a much more rapid oscillation, which under certain circum stances occurs in stomatal regulation. Th...
متن کاملOrthologs of Arabidopsis thaliana stomatal bHLH genes and regulation of stomatal development in grasses.
Stomata are adjustable pores in the plant epidermis that regulate gas exchange between the plant and atmosphere; they are present on the aerial portions of most higher plants. Genetic pathways controlling stomatal development and distribution have been described in some detail for one dicot species, Arabidopsis, in which three paralogous bHLH transcription factors, FAMA, MUTE and SPCH, control ...
متن کاملBlood serum osmotic and ionic regulation of wild adults and reared juvenile Persian sturgeon, Acipenser persicus
The osmoregulatory system was studied in wild adult and reared juvenile Persian sturgeon, Acipenser persicus. The mean osmolarity in blood serum of specimens from the Caspian Sea, estuary, the Kouraneski pools and the rearing tanks were 305.3±14.3, 308.7±25.8, 265.0±19.1 and 259.3±8.8 mosmol/L, respectively; the mean concentrations of Na+ were 151.2±6.3, 152.2±8.4, 142.5±5.9 and 131.4±4.1 meq/L...
