- Abstract
The aim of our research was to establish the effect of some cultivation stages in ecological system in which are use the LED light on biological material of three Romanian tomato varieties. For this purpose, young tomatoes (Lycopersicon esculentum Mill.) plants have been grown in protected crop space (vegetation house), by daily supplementing natural light for short periods of time with light provided by high power LED panels with red, blue and white monochromatic light. In order to carry out the integrated studies of the cultivation method in the ecological system, products accepted as natural and biodegradable and approved in Romania, for fertilization and control of the attacks of diseases and pests, were used. The tested varieties were selected with indefinite habitus and special forms of fruits, namely: Sonia de Buzău, Hera and Coralina. The recorded differences in the increase of the stems' length (average values) recorded, after 50 days from the beginning of the experiments, have revealed to us that the results are differentiated according to genotype, spectrum and exposure time to the used additional light. Plants of the variety "Sonia de Buzău" exposed daily under LED light recorded high values in most variants, followed by those of the variety Hera and Coralina. The results obtained after the application of additional treatments with LED light, were dynamically analysed, evaluated by statistical calculation and compared with the values obtained by the Control plants maintained only under the effect of natural light and which were treated with the fertilization and phytosanitary protection products.
