Post-anthesis Drought Stress Effects on Photosynthesis Rate and Chlorophyll Content of Wheat Genotypes
Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...
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 کاملEstimation of Chlorophyll Content in Papaya Leaf using Mathematical Operations
ABSTRACT Leaf color is used as a guide for assessments of nutrient status and plant’s health. So that a new method is proposed for the detection of Chlorophyll content based on the leaf color. Based on green color present in leaf we can estimate the chlorophyll content in leaf. The proposed equation produced superior results with the true value of chlorophyll content measured in the laboratory ...
