Solarisation is 

  • formation of chlorophyll

  • destruction of chlorophyll

  • utilisation of sunlight

  • effects of solar light


B.

destruction of chlorophyll

Photosynthesis starts at very low intensity of light. High intensity of the same causes oxidation and destruction of pigments, enzymes and intermediates and this destruction is termed as solarisation. Therefore, it causes reduction in photosynthesis yield.
