Impact of stone quarrying on the pigment concentration and Productivity of Paddy (Oryza sativa, L)

Abstract

The response of plants to air pollutants in stone quarrying industry is variable and depends on the individual genotype, age, state of growth, concentration of pollutants and duration of the onslaught. It affects the opening of stomata resulting in reduction in photosynthesis which in turn leads to reduction in growth, development and finally influences adversely the productivity and yield of crop plants. A study carried out in selected quarry locations revealed the effect of dust pollution on the growth, yield, pigment concentration and various other grain characteristics in paddy plants.
