Abstract

The aim of this investigation was to study the effect of physical (ultraviolet light) and chemical mutagen (methyl salicylate) on common bean (Phaseolus vulgaris L.) and how they had positive or negative effect on alpha-amylase activity, phenological plant traits (days to flowering, days to maturity, days of pod fill) and agronomic traits (number of pods per plant; weight of pods per plant; Number of seeds per pod; number of seeds per plant; weight of seeds per plant; plant height; pod harvest index), seed and pod morphological characteristics (seed length; seed width; pod length; pod width). Seeds of common bean were exposed to ultraviolet (UV) light for different periods of exposure time (3 and 5 h) and were soaked with two different methyl salicylate (MeSA) concentrations (0.01 and 0.05 mM). The results indicated that the 5 h exposure to UV light plants were indicated to positively affect alpha-amylase activity, phenological and agronomic traits, seed and pod morphological characteristics as compared to control and other treatments while 0.01 mM MeSA significantly negatively impacted them. Traits of plants exposed to UV light for 5 h were significantly improved. This research could provide a valuable source of materials for common bean breeding.
