Abstract
Research is still needed to optimize and evaluate growing methods and systems, their impact on yield quantity and quality, as well as economic viability.
The aim of this research was to evaluate the temperature and light conditions for strawberries grown vertically in an open area and a greenhouse, as well as their vegetative parameters and chemical composition in response to these conditions.
Frigo plants of three strawberry cultivars – ‘Honeoye’, ‘Sonata’, and ‘Rumba’ – were planted in double-layer plastic greenhouse and open field conditions.
Plants were grown in growing bags with sphagnum peat.
Bags were installed in a vertical growing system in three layers – 10, 90, and 155 cm.
The light intensity and spectral content were detected by using a spectroradiometer.
The content of chlorophylls, carotenoids, phenols, and flavonoids in leaves was analyzed in this research.
Daily temperature fluctuations were notable in both areas, especially on sunny days and in the greenhouse.
It was concluded that 56.6% of the light intensity was lost in the greenhouse compared to the open area, and the bottom levels had only 71% of the light intensity compared to the top levels.
Moreover, the light intensity in the bottom levels also varied more due to shadows.
However, these differences in light intensity did not significantly influence the average number of leaves and inflorescences per plant.
The differences in plant growth and biochemical content between cultivars and growing systems were detected.
Although significant differences in leaf biochemical composition were found in the tested growing conditions, cultivars responded differently to them.
