Photosynthesis and Chlorophyll Fluorescence Reaction to Different Shade Stresses of Weak Light Sensitive Maize
A split-plot experimental study was conducted to evaluate the effect of different shade stresses on photosynthesis and chlorophyll fluorescence of maize leaves.The experiment was designed on the south farm of Special Corn Institute, Shenyang Agricultural University, China.Data was collected from the day maize tasseled (Jul. 21) to the beginning of grouting (Aug.12 ) under 18%, 28%, 38%, 60%, an...
متن کاملcomparison of photosynthesis parameters and leaf chlorophyll content and fluorescence of safflower cultivars under slaine conditions
to comparison the photosynthetic parameters and leaf chlorophyll content and fluorescence of safflower (carthamus tinctorios l.) cultivars under salinity stress, a pot experiment was carried out as factorial based on completely randomized design with three replications in summer 2011 in university of yasouj. first factor included four salinity levels (zero, 75, 150 and 225 mm (formed as 20 to 1...
متن کاملdrought stress effects on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in chickpea (cicer arietinum l.) genotypes
in order to evaluate of physiological traits, related to drought tolerance, an experiment was carried out in controlled condition. the experiment was conducted to assess the effect of drought stress on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in two tolerant genotypes (mcc392 & mcc877) and two susceptible genotypes (mcc68 & mcc448) were grown in drought stress (25% f...
متن کاملEffects of Cadmium and Salinity on Growth and Photosynthesis Parameters of Brassica Species
Hydroponic experiment was conducted to investigate the sole and combined effects of cadmium and salinity on growth and photosynthesis of Brassica napus (cultivar Abasin) and Brassica juncea (cultivar NIFA-Raya). Cadmium (as CdCl2; 3 and 6 μmol L) and NaCl (100 and 200 mM) were added either alone or in combination in Hoagland solution along with non-treated controls. Cd and NaCl treatments impos...
متن کاملUsing Chlorophyll Fluorescence to Study Photosynthesis*
Each quantum of light absorbed by a chlorophyll molecule rises an electron from the ground state to an excited state. Upon de-excitation from a chlorophyll a molecule from excited state 1 to ground state, a small proportion (3-5% in vivo) of the excitation energy is dissipated as red fluorescence. The indicator function of chlorophyll fluorescence arises from the fact that fluorescence emission...
