Sažetak
The aim of this research was to determine the effect of nanoparticle-coated glass (Germanium (Ge), Titanium nitride, Ge + Silicon) as greenhouse cover on the morphology and yield of lamb's lettuce. The tested glasses differ in terms of total light transmittance and transmittance of wavelengths 450 and 650 nm. The transmittance of the nanoparticle-coated glasses ranged from 44.4 to 79.1% of the light transmittance of standard horticultural glass. Transmittance for 450 and 650 nm wavelengths ranged from 3.1 to 63.2% and from 39.9 to 77.1%, respectively. The air temperature and humidity sensor and a PAR sensor connected to the data logger were installed in the greenhouses. During harvest, conducted 30 days after planting, total biomass, number of leaves, mass of rosettes and mass of roots were determined. The highest values of all parameters were determined for lamb's lettuce grown under standard horticultural glass (plant biomass 2.65 g, rosette mass 2.53 g, root mass 0.12 g, 11.5 leaves, yield 1.265 kg m- 2). In greenhouses covered with tested anoparticle-coated glass, the highest values of monitored traits were obtained under glass coated with Germanium. Although a significantly lower yield was achieved under the tested nanoparticle- coated glasses, the use of glass with suitable structure has an advantage, especially in the warmer part of the year due to reduced light transmittance, as there is a lower temperature gradient compared to standard glass
