| Abstract:
In order to evaluate the plants (Tomato) influence by some photoselective films (2 materials x 3 colours) the Institute, by adequate methods and equipments, started a trial to control qualitative, thermical and hygrometric effects on some bioagronomic parametres in two different cubatures. The first results show a positive influence of the colourless film PVC to the cubature ½ on the production of commercial berries and on the examined bioagronomic parametres. This influence is in relation with thermical values which interacted positively with the intensity and different composition of the light. After the first results, it appears the hygrometric values did not interact with materials, colours and cubature and they did not influence the considered parameters. | |
