The steady and transient response of "dynamically" dry moist atmospheres to uniform sea-surface temperature (SST) is studied. Specifically, the latent heat (Lv) water vapor varied, so that for small Lv, substance essentially a passive tracer from dynamical point view. Despite lack SST gradients, general circulation with Hadley Ferrel cells observed relatively stronger coupling. Organized precip...

Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

In the range 16 to 29 degrees C, increases in temperature caused large (two-to threefold) increases in growth velocity, growth strain rate, and biomass deposition rate in primary roots of maize, Zea mays L. Temperature had small effects on root diameter, fresh weight density, and dry weight density, and negligible effects on length of the growth zone and growth strain at particular positions.

Atmospheric carbon dioxide concentration ([CO2]) and other greenhouse gases have risen over the past few decades. If this continues, it could indirectly lead to increases in global temperature. Responses of grain legume crops (soybean, dry bean, peanut and cowpea) to elevated [CO2] and interactions with temperature are summarized. Our research shows that, in the absence of biotic (pests, diseas...

ajowan is one of the endemic plants in khorasan province, and there is a little information on its tolerance to cold stress. in order to study freezing tolerance of ajowan, an experiment was conducted in faculty of agriculture, ferdowsi university of mashhad, based on factorial-completely randomized design with three replications and three ecotypes of ajowan (neishabour, birjand and torbat-e-he...
