Applying LED plant grow lights on the vegetable seedling

LED source of light control vegies morphogenesis and growth is a vital technology in greenhouse planting. The plant can perception and assimilate light through photoreceptor systems. After that, transported to control morphological changes by intracellular messengers. Photomorphogenesis is counted on light to regulate the differentiation, structure, functionality and the production of tissues and organs.

Plant seedlings are a significant portion of facility agriculture. Uninterrupted drizzly weather conditions lead to lack of light and unnecessary growth, that will affect the growth of greens, bloom bud differentiation, and fruits improvement, and finally influence the yield and quality. A number of plant growth regulators are accustomed to managing the growth of seedlings on stream, however, the false usage will cause toxic contamination.

LED plant grow lights have several positive aspects in the supplement of light, it can be an achievable method to increase seedlings. Based on the experimental information, in the low light environment, the green light LED grow lights can accelerate the growth of cucumber seedlings. In contrast to the low light, the red and blue light improved healthy index 151.26% and 237.98% correspondingly. Furthermore, compared to single color light, the healthy index enhanced by 304.46% by the used composite light of red and blue light. Red light can boost the amount of leaf, dry and fresh quality, leaf area, stem dimension, plant height, healthy index, SOD activity, root activity and soluble protein content of cucumber seedlings.

In comparison with natural light, LED red light and blue light can highly raise the leaf area, dry matter quantity and a healthy index of tomato seedlings. LED green light can truly enhance the biomass of cucumber and tomato seedlings, and the health index, stem diameter, and fresh-dry quantity of seedlings with the enlargement of green light intensity. LED red and blue mixed light can improve the stem diameter, leaf area, plant dry weight, root-shoot ratio, and healthy index of eggplant.

The above shows the benefits of vegetable seedlings cultivated by applying LED grow lights are very noticeable.
