Comparative Performance Study of Solar Photo-Voltaic Panel on Rose

Comparative Performance Study Of Solar Photo-voltaic Panel Operated Different Light Sources On Quality Of Rose: Light intensity and colour of light affects a plant growth and flowering. Light is probably the most complex and variable environmental factor to which the plant is exposed. All its components: quality, quantity, direction can modulate plant growth and development either through an effect on photosynthesis. Decrease in light intensity and duration of light period owing the seasonal changes or shading reduces the yield of roses. Different components of productivity such as bud breaking, rate of flower abortion, formation of renewal shoots, time periods between harvests, length, weight and diameter of stem and flower buds, leaf area and pigmentation of petals are affected by light. Supplementary lighting of relatively high levels of irradiance, especially during periods of low solar radiation, results in increasing number of flowers.
