The effect of high intensity radiation on plant growth in greenhouses. There were no large tractors involved, no dusty fields, no uncontrollable storms to destroy your crop (well that is what I thought). As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. At low light intensities above the light compensation point (LCP), photosynthetic rate increases proportionally to the light intensity and reaches a maximum. As temperature increases the number of collisions increases, therefore the. Light intensity determines the competitive and reproducible traits of many understory plants. Marine Biology 147: 225234. As the sun moves across the sky, different parts of the greenhouse will be irradiated at different times of the day, and the time when this occurs is often important. At each combination of light and temperature, sublethal concentrations of the growth regulator induced cumulative reductions in the relative growth rate and the order of the depression increased progressively with concentration-3, 9, 27, and 45 p.p.m. This law is named after Sir David Brewster, a Scottish physicist, who proposed the law in the year 1811.
