Light is the driving energy source for photosynthesis and carbohydrate accumulation in plants. During propagation, cuttings and seedlings require a minimum quantity of light to provide the energy for root initiation and development. Light intensities below this minimum result in little or no root development, leading to a delayed crop or rooting failure. Conversely, too much light can bleach leaves and reduce root formation due to excessive stress on the cuttings.
