Morphogenesis and productivity of Cucumis sativus L. hybrids under the thermic polyethylene films modified by coating of metals by magnetron sputtering

Abstract

The results of the investigation of morphogenesis and productivity characteristics of Cucumis sativus parthenocarpic hybrids Marinda and Kurazh in ontogenesis in greenhouses under the thermic films are presented. The thermic films have IR- and UV-shielding properties at the expense of coating with nanoparticles of copper compounds (film TF1) and compounds of silver and copper (film TF2) on the surface of films by magnetron sputtering. It is shown that thermic films contributed to levelling of day and night temperatures. The use of the film TF1 favoured seeds germination, activation of plant growth and development, shortening of period of the fruiting beginning and increase in productivity of hybrid Marinda by 13% and hybrid Kurazh by 35%. The use of the film TF2 led to inhibition of growth processes of both hybrids and decrease in their productivity.
