Influence of light stimuli on the habitus of basil (Ocimum basilicum L.) under daylight conditions
- Due to a lack of light and a morphologically determined top heaviness, the cultivation of potted herbs leads to unstable plants in winter months. Former studies suggest that plants become more compact with high intensity pulsed light exposure (> 1,000 µE). In this study, preliminary experiments were carried out in climate chambers regarding the effects of additional light intensities and qualities as well as sun fleck duration on young basil plants (Ocimum basilicum L.). Those experiments provided evidence of reduced height and fresh mass of basil plants, as well as thinner stems and wider leaves. In succession, the aim of the main study was to validate the preliminary results in practice and to investigate whether the outlined effects could lead to an increase in stability. A greenhouse trial was carried out at producer Gartenbau Schulz, Papenburg, Germany, exposing basil to 1,000 µE light stimuli by a white-blue LED.
