Effect of light colour on the growth of tomato (Lycopersicon esculentum Mill.) transplant


Transplants of tomato cultivar ‘Recento F1 ’ were grown under the fluorescent lamps emitted daylight, yellow, green, blue and white light with quantum irradiance on the apical bud level 57 µmol m -2 s -1 . The growth dynamic and the most important morphological attributes of the transplant were investigated. It was observed favourable influence of the blue light. Plants exposed to blue light flowered early, were short, with thick and strong stem, shortened internodes, enhanced participation of the dry mass in fresh mass. Yellow light influenced unfavourable. Plants grown under yellow light had delicate stem, small leaves, reduced fresh and dry mass and flowered late. Employment of the blue light emitted lamps can be an efficient method of the tomato transplant growth control.
