WHY WORRY ABOUT CROP STRESS?

Photon Improves Crop Productivity Even during a “normal” growing season, crops experience reduced productivity  due to adverse conditions on any particular day.

It is estimated that up to 60 percent of all crop loss is due to stress caused by heat, cold, drought, moisture and light.  Not enough or too much of these conditions at the wrong time saps a plants’ ability to thrive to its fullest potential.

Even during a “normal” growing season, there are stress periods affecting yield.  There is no ideal growing season where crop stress does not occur at all – it is a matter of degree of stress. In face, short-term changes can be more damaging as plants do not have much time to adapt to the stress.

PHOTON temporarily stimulates key stress sensing enzyme systems in plants, so that they are prepared to react quickly and effectively to environmental stresses. This includes excessive temperatures, drought, salinity and high radiation.

Crops grown in open fields are subject to adverse environmental conditions. They receive more light than needed for photosynthesis, and are subject to a range of temperatures. With increasing temperatures, the conversion of light to sugar is impaired. This phenomenon is known as photoinhibition. At higher temperatures, photoinhibition begins at lower light intensities.

 

With photoinhibition, damaging free radicals (ROX) are formed that damage membranes and other cell components. This damage is repaired through respiration.

 

Under stress, crops produce less carbohydrate, and consume the reminder to repair damage, limiting what's available for yield and quality, this limiting yield at harvest.
