The Effect of LED Lighting on The Growth of Seedlings of Hybrid Tomato

A study was conducted to evaluate the effect of LED lighting on the growth of seedlings of hybrid tomato plants. Four hybrids (Captain F1, Refiner F1, Coral Reef F1 and Fire F1), seven treatments of irradiators (monochromatic red, green, blue, white) and three dual light treatments (green+blue, blue...

Description
Summary:A study was conducted to evaluate the effect of LED lighting on the growth of seedlings of hybrid tomato plants. Four hybrids (Captain F1, Refiner F1, Coral Reef F1 and Fire F1), seven treatments of irradiators (monochromatic red, green, blue, white) and three dual light treatments (green+blue, blue+red, green+red) were carried out in the laboratory of artificial climate. Radiation with monochromatic had a role in increasing hypocotyl length, the height of plant, transpiration and stomata connection. The results have shown a significant effect on radiation with monochromatic red on hypocotyl length (73.00mm) and the height of plant (30.94cm). Plants radiation with monochromatic blue gave the highest transpiration (4.69 mmol/m 2 .s) and stomatal conductance (0.30 mol./m 2 .s). The dual radiation had a role in increasing dry weight for the plant and leaf chlorophyll content (SPAD). Radiation with (green+red) provided the best stem dry weight (0.91g). Plants irradiated with (green+blue) exhibited the highest leaf dry weight and root dry weight (1.96g and 3.12g respectively). Plants radiation with (blue + red) showed the highest leaf chlorophyll content (SPAD) (559.19). In the monochromatic light, the effect of hybrid Fire F1 showed the highest hypocotyl length (64.11mm) and height of plant (29.00 cm), and hybrid Refind F1 had the highest transpiration (3.58 mmol/m 2 .s) and stomatal conductance (0.23 mol./m 2 .s). In the binary spectral effect, the hybrid Coral reef F1 resulted the highest stem dry weight, leaf dry weight and root dry weight (0.68 g,1.76 g and 2.39g respectively), and hybrid Refind F1 had the highest leaf chlorophyll content (SPAD) (468.27).
