Abstract EN
Heat stress (HS) is the major constraint to crop productivity worldwide.
The objective of the present experiment was to select the tolerant and sensitive genotype(s) on the basis of morphophysiological and biochemical characteristics of ten Vicia faba genotypes.
These genotypes were as follows: Zafar 1, Zafar 2, Shebam 1, Makamora, Espan, Giza Blanka, Giza 3, C4, C5 and G853.
The experimental work was undertaken to study the effects of different levels of temperature (control, mild, and modest) on plant height (PH) plant1, fresh weight (FW) and dry weight (DW) plant1, area leaf1, content of leaf relative water (RWC), proline content (Pro) and total chlorophyll (Total Chl), electrolyte leakage (EL), malondialdehyde level (MDA), hydrogen peroxide (H2O2), and activities of catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) enzymes.
HS significantly affected growth performance of all genotypes.
However, the magnitude of reduction in genotypes ‘C5’ was relatively low, possibly due to its better antioxidant activities (CAT, POD and SOD), and accumulation of Pro and Total Chl, and leaf RWC.
In the study, ‘C5’ was noted to be the most HS tolerant and ‘Espan’ most HS sensitive genotypes.
It was concluded that the heat-tolerant genotypes may have better osmotic adjustment and protection from free radicals by increasing the accumulation of Pro content with increased activities of antioxidant enzyme.
