Abstract:
Phytohormones are the important regulators of plant response system to biotic and abiotic stresses. They also play an important role in the interaction of plants with pollinators by affecting floral development, nectar secretion, volatile organic compounds emission. This study investigated the role of jasmonic acid signaling in response to exogenous JA application and its impact on floral traits, nectar composition, and honeybee foraging behavior. JA was applied in three concentrations (low: 0.5 mM. medium: 1.0 mM, and high: 2.0 mM). For better understanding the role of JA, herbivore feeding and mechanical damage were also compared. As obvious from the results, JA signaling enhanced in the treated plants resulted in increased JA-content. Increased in JA-signaling reduced the nectar volume, flower size, and volatiles. This caused reduction in visitation of honeybee and reproductive outcome. The honeybees' behavioural data revealed significant difference among different treatments, visiting less frequently the herbivory damaged and enhanced JA induced plants, honeybees spent less time and exhibited lesser landing success and rates of revisitation. This study presents the mechanistic insights on how it affects the honeybee foraging behavior by altering floral development, metabolism, and volatiles.
