23 Feb Harnessing Radiation Use Efficiency for Crop Improvement
फसल सुधार के लिए विकिरण उपयोग दक्षता का दोहन The energy of the entire ecosystem is reliant on the sun, which is the sole source of energy for all living organisms, directly or indirectly. Solar radiations reach from sun to earth and helps in photosynthesis, a process by which plants transform light energy into chemical energy. The rate of accumulation of dry matter of all plants is completely dependent on the interception of light energy from the sun (400–700 nm wavelength range), known as photosynthetically active radiation (PAR). Global climate changes are affecting crop yield potential and reducing the yield of crop significantly. A rapid rise in population is expected in the near future (about 10 billion by 2050), which might raise food consumption and put load on the agricultural system. So, we need to improve the efficiency of crop varieties to produce more yield with less resources. Crop productivity is the outcome of the amount of radiation, water, or nutrients captured by the crop and how efficiently those resources are used, which could only be enhanced by improving the traits related to yield and biomass production, such as Radiation use efficiency (RUE). RUE is the efficiency of the crop plant for using intercepted radiation to produce the biomass of the plant. With the...
