Description A study with complete randomized design with five replications was conducted in Koya city during winter season 2016-2017 to study the effects of four light spectrums (white, blue, green, and red) in addition to the control (plants grow under sunlight) on some vegetative growth, photosynthetic pigments and stomata characteristics of Vicia faba L. cv. Franchi. The results showed that plants grown under green light increased plant high significantly to 49.67 cm compared to other treatments, whereas the lowest value was 14.33 cm which recorded in control treatment. Highest nodes and leaves number was recorded in plants of white light treatment (6.00 nodes/plant and 4.67 leaves/plant), whereas the lowest number recorded in the plants grown under red light (3.33 nodes/plant and 2.67 leaves/plant). Leaf area of the control plants increased significantly to 195.75 cm3 compared to other treatments. Root length increased significantly to 25 cm in plants exposed to blue light compared to other treatments except for the red light (22.27 cm). The lowest amount of chlorophyll a and b and higher content of total carotenoids (15.78, 9.44 and 3.12 mg/g fresh weight) were recorded in plants exposed to green light significantly compared to other treatments, whereas the highest chlorophyll an (18.38 mg/g fresh weight) was recorded in white light treatment and chlorophyll b (20.40 mg/g fresh weight) in control plants which also gave the highest amount of total carotenoids (0.54 mg/g fresh weight). Stomata number increased significantly in plants exposed to red light to 76.67 and 120.00 stomata/mm2 for adaxial and abaxial leaves surfaces respectively, whereas lowest number was recorded in plants exposed to green light (53.33 stomata/ mm2). Published 01 August 2018DOI: 10.14500/icpas2018.bph40http://dx.doi.org/10.14500/icpas2018.bph40
