The Effect of Light on Plant Growth
Although there is a natural growth cycle for every plant, the vegetative and flowering stages of growth are directly influenced by light. Artificial lights allow for year-round growth and quick production, but the intensity and nutrients that natural sunlight offers can never truly be duplicated. Without light, we would not have green plant life, vegetable gardens would not produce and flowers would not bloom. Light gives food and energy to plants through photosynthesis and makes everything flourish. It is an essential part of all life on Earth.
Efficient acclimation to different growth light intensities is essential for plant fitness. So far, most studies on light acclimation have been conducted with plants grown under different constant light regimes, but more recent work indicated that acclimation to fluctuating light or field conditions may result in different physiological properties of plants. We performed a thorough characterization of the morphological, physiological, and biochemical properties focusing on photo-protective mechanisms. NatL plants, however, were found to combine characteristics of both LL and HL grown plants, leading to efficient and unique light utilization capacities. Strikingly, the high energy dissipation capacity of NatL plants correlated with increased dynamics of thylakoid membrane reorganization upon short-term acclimation to excess light. We conclude that the thylakoid membrane organization and particularly the light-dependent and reversible unstacking of grana membranes likely represent key factors that provide the basis for the high acclimation capacity of NatL grown plants to rapidly changing light intensities. Efficient acclimation to changing environmental conditions is a prerequisite for the survival and competitiveness of plants in the field.
The most important variable affecting plant growth is light exposure, and it is therefore important to measure the amount of light your plants receive. Prof Gert Venter explains how this is done. The most important concept to understand when growing plants is the rule of limiting factors, which determines plant quality. Hydroponics cannot compensate for poor growing conditions, such as improper temperature, insufficient irrigation, nutrient deficiencies, pest and disease problems, or poor light. If plants do not receive enough light, they will not grow at their maximum rate or reach their maximum potential, regardless of how much of any other variable — water, growth medium or fertiliser — they receive.
