Salicylic acid induced resistance in fruits to combat against postharvest pathogens: a review
2015
Hussain, Muzammil | Hamid, Muhammad Imran | Ghazanfar, Muhammad Usman
Salicylic acid (SA), the plant hormone, is extensively involved in signalling pathway, primarily in defence to induced local and systemic resistances in fruits against postharvest pathogens. Exogenous application of SA on fruits at optimum or non-toxic concentration provided efficient control of decay caused by postharvest pathogens. SA has direct fungitoxic effect on pathogen growth. This review scrutinises the control of various postharvest diseases by the application of SA on different fruits. Furthermore, physiological mechanism involved in inducing resistance is also discussed. These findings are necessary for understanding the proper function of SA in harvested fruits. In future, there is a need to correlate the efficacy of SA with environmental conditions and should emphasise on molecular paths involved in signalling of induce resistance.
