    The ratio of the amount of plant tissues that have supportive functions to the amount of those that have growth functions. Plants with a higher proportion of roots can compete more effectively for soil nutrients, while those with a higher proportion of shoots can collect more light energy. As a result of which more water will be available for transpiration by the shoot. This is only possible if root area equals the shoot area. According to Parker, High root/shoot ratio increases the rate of transpiration whereas low root/shoot ratio decreases the rate of transpiration.It's important because the root system plays a fundamental role in taking nutrients and water, and as the absorption at the root level is more intense, the higher the biomass, hence the agricultural production. Greater root/shoot ratio means greater root density and root interception for nutrient uptake.
