The physiological and biochemical parameters’ evaluation of the broad bean (Vicia faba L.) exotic genotypes obtained from the ICARDA (International Center for Agricultural Research in the Dry Areas) became this study’s aim. Particularly, when analyzing the plant leaf spectrophotometrically, the total water content in the plant leaf ranged from 74.9% to 88.9%. In the combing phase of broad bean, the leaf chlorophyll a was highest in the genotypes G-15 and G-29 (2.07 mg/g), chlorophyll b in G-29 was 1.27 mg/g, and carotenoid content in the genotype Bakla UNV-851 was 0.95 mg/g, while G-35 was higher for total pigment content (3.14 mg/g). At the flowering phase, the superior value recorded for chlorophyll a was in the genotype Bakla UNV-851 (2.10 mg/g), chlorophyll b was in G-35 (1.20 mg/g), carotenoid content was in Bakla UNV-851 (0.96 mg/g), and total pigment was in the genotype G-26 (3.22 mg/g). For chlorophyll a content, the supreme value resulted in the genotype Bakla UNV-851 (2.12 mg/g); chlorophyll b emerged to be higher in the genotype G-1 (1.47 mg/g), the carotenoid content was greater in Bakla UNV-851 (0.90 mg/g), and the total pigments were highest in the genotype Bakla UNV-852 (3.43 mg/g).
Broad bean (V. faba L.), growth phases, photosynthetic
The water deficiency in different growth phases of plants leads to disruption of physiological processes. The highest total water content resulted in the genotype G-22, while it was slightly lower in the G-50. The highest transpiration rate was evident in the genotype Bakla UNV-851 and the lowest in the genotype G-26.
