Effect of Different Colours of Light on Chosen Aspects of Metabolism of Radish Sprouts with Phosphoromic Approach.

Among various environmental factors, light is a crucial parameter necessary for the germination of some seeds. Seed germination is an important phase in the plant life cycle, when metabolic activity is resumed and reserves are mobilized to support initial plant development. Although all nutrients are extremely important for proper physiological and biochemical development of plants, phosphorus (P) seems to play a special role, as it is an essential component of all important structural and functional substances which compose the cells of plants. We believe that transformations of the forms of phosphorus accompanying metabolic activity of germinating seeds determine the efficiency of this process, and thus the seedling's metabolic status. Therefore, we decided to study the changes in the major phosphorus-containing substances in radish sprouts during the first phase of growth. The effect of different colours of light on the quality parameters in radish, as a model plant, during germination, was evaluated. Contents of Pi, adenylates, antioxidants, pigments, phytase activity, and P NMR phosphorus profile were investigated. Based on the results of our study, we may propose the phosphoromic approach as an important metabolic parameter determining the physiological status of the plant.
