Green light is generally less effective for photosynthesis in plants and does not contribute significantly to seedling bending. Seedlings grown under green light may not bend and can display tall and spindly growth. Knowledge of how light affects plant growth is critical for horticulture and greenhouse management.
The influence of light on plant growth is a key aspect of greenhouse management and horticulture. Plants use light of different wavelengths for various physiological processes. It is well-known that green light is generally reflected by plants, and not as efficiently used for photosynthesis as red or blue light.
When considering the effect of green light on seedlings, based on the information provided, it is likely that green light does not significantly promote bending (phototropism) or prevent tall and spindly growth as in darkness. As such, green light exposure to seedlings might result in plants that do not bend towards the light, a phenomenon mainly driven by blue light, and they may grow tall and spindly, similar to plants grown in the dark where etiolation occurs due to lack of light.
In horticultural practices, knowledge of how different light wavelengths affect plant growth can be practically applied, such as using red light to promote flowering in long-day plants or applying plant hormones to control fruit ripening. Understanding plant responses to external stimuli, including light, is crucial for enhancing crop yield and quality, as well as developing plant breeds that are more resistant to pests and adverse conditions.
The probable question may be:
How does green light exposure affect seedling growth, particularly in terms of phototropism, prevention of tall and spindly growth, and overall impact on plant development in comparison to red and blue light?
