The Efficiency of LED Irradiation for Cultivating High-Quality Tomato Seedlings

Light qualities are considered to affect many plant physiological processes during growth and development. To investigate how light make an influence on tomato seedlings under greenhouse conditions, the morphological parameters of (Fortizia F1RC hybrid) were studied three supplemental irradiations such as light-emitting diodes with nanoparticle coating (LED 1—Red diodes); Blue, Green, Yellow, Red 2), traditional high-pressure sodium (HPS) lamps different photosynthetic photon flux density same irradiation time for 33 days. Morphological appearances groups between treatments, that is, plants LED-1 LED-2 shorter than those HPS, while stem diameter, leaf area, dry fresh weights, health indices grown alternative sources higher cultivated HPS lights. However, height was in containing treatment. Photosynthetic pigments shown have a significant difference respective LEDs. The levels leaves LED 1 2, lower underwent control Based data statistical analysis, LEDs proved be beneficial factors conditions.
