The diurnal variations in the factors of photosynthesis reduction under well-watered greenhouse conditions remain poorly understood. We conducted measurements gas exchange and chlorophyll fluorescence strawberries (Fragaria × ananassa Duch.) for three sunny days. Quantitative limitation analysis was also to investigate photosynthetic limitations [stomatal (SL), mesophyll (MCL), biochemical (BL...

Progress in understanding the network of mechanisms involved in maize primary root growth maintenance under water deficits is reviewed. These include the adjustment of growth zone dimensions, turgor maintenance by osmotic adjustment, and enhanced cell wall loosening. The role of the hormone abscisic acid (ABA) in maintaining root growth under water deficits is also addressed. The research has t...

'Krafft disease', occurring in camels living in the very arid areas of North Africa, is characterized by spontaneous fractures of costal and/or appendicular bones. To better understand the mechanisms of this, we studied the influence of water restriction on plasma and urinary markers of bone metabolism in camels. Eight 2-year-old nonpregnant, nonlactating camels were studied at the research sta...
