Effects of Soil Drought on Photosynthesis and Chlorophyll Fluorescence in Bean Plants
The effects of soil drought on photosynthesis and chlorophyll fluorescence in the leaves of three bean (Phaseolus vulgaris L.) genotypes were studied. Drought was imposed 14 days after plants growing up. In the primary leaf of all the cultivars, water stress led to a noticeable decrease in both the initial slope of the An/Ci curve and Amax. The most strongly marked reduction in leaf CO2 exchang...
متن کاملAn investigation on the possibility of use of chlorophyll fluorescence to study the stomatal behaviour in plants under drought stress
Stomata play a key role in the control of plant water relations and photosynthesis. A rapid non-destructive method to study the stomatal behaviour in aerial parts of plants is important for researchers in plant sciences and agricultural fields. Stomata close in response to drought stress. Stomatal closure causes lower availability of CO2 inside the leaf and thus a decrease in the rate of carbox...
متن کاملChlorophyll a fluorescence transient as an indicator of active and inactive Photosystem II in thylakoid membranes.
Upon illumination, a dark-adapted photosynthetic sample shows time-dependent changes in chlorophyll (Chl) a fluorescence yield, known as the Kautsky phenomenon or the OIDPS transient. Based on the differential effects of electron acceptors such as 2,5-dimethyl-p-benzoquinone (DMQ) and 2,6-dichloro-p-benzoquinone (DCBQ) on Chl a fluorescence transients of spinach thylakoids, we suggest that the ...
متن کاملMorpho-Physiological Characterization Related to Drought Tolerance of Common Bean (Phaseolus Vulgaris L.) Genotypes
Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...
