In our previous study, we observed that paracetamol (panadol) influences the germination rate and growth biomarker of the Vigna radiate plants. To dissect out the paracetamol mediated changes in this study was undertaken. For this study, 10 days old seedling of Vigna radiata exposed to range of pandol concentration (.005, .01, .1, or 1.0 mg/L) through foliage of plants and harvested at 31st day. Obtained data revealed the dual response of panadol concentration: 0.1 mg/L of panadol significantly increased chlorophyll and leaf gas exchange traits (net photosynthetic rate, stomatal conductance, internal carbon dioxide concentration, water use efficiency and maximum quantum yield of PS II), whereas, 1.0 mg/L of panadol significantly reduced the above parameters. It is therefore concluded that low level of panadol enhanced photosynthetic efficiency of Vigna radiata plants; however, the response is concentration dependent and could be used as growth regulators for Vigna radiata plants.
