late-season drought is the major constraint reducing the productivity of chickpea. this experiment was carried out to study response of root and shoot characteristics in 12 chickpea genotypes to drought stress. two-drought stress levels (-3 and -6 bar) induced by peg 6000 and control in hydroponic condition at green house was performed. leaf relative water content (rwc), plant height, number of...

Relative water content, solute concentrations, and osmolality were determined in the water storage tissue (hydrenchyma) and the assimilatory tissue (chlorenchyma) of the succulent leaves of Peperomia magnoliaefolia (Jac) (Piperaceae) during slow desiccation. Relative water loss was significantly greater for the hydrenchyma than for the chlorenchyma. When whole leaves had lost 50% of their initi...

decrease in genome content may play a role in environmental adaptation. many studies were reported significant correlation between genome size, weather condition and germination percentage. relative genome content and its correlation with seedling establishment of 14 populations of tall fescue collected from various regions in iran and two commercial tall fescue cultivars were studied under dro...

The aim of this experiment was to determine the response of dill (Anethum graveolens L.) towater deficiency and salinity. In spring, dill biomass decreased with increasing water deficiencydue to a reduction in the number and mean weight of leaves per plant. The concentrations ofchlorophyll, carotenoids, vitamin C and total phenolics within the leaves were unaffected bywater stress, but the Cl, ...

plants are always exposed to vast aspects of either environmental biotic or abiotic stresses and those stresses affecting the plant growth and therefore crop production. molecular and physiological mechanisms influence plant resistance to environmental stresses, therefore the identification of these mechanisms can be an important step in challenging the damages. in this study, plant physiologic...
