The Journal of Applied Botany and Food Quality is the Open Access journal of the German Society for Quality Research on Plant Foods and the Section Applied Botany of the German Society for Plant Sciences (DBG). It provides a platform for scientists to disseminate recent results of applied plant research in plant physiology and plant ecology, plant biotechnology, plant cultivation, phytomedicine, plant nutrition, plant stress and resistance, plant microbiology, plant analysis (including -omics techniques), and plant food chemistry. The articles have a clear focus on botanical and plant quality aspects and contain new and innovative information based on state-of-the-art methodologies.


icons of sustainable development goalsSpecial Section 2022 – Applied Botany for Sustainability

Effects of climate change emerge in many ways. Among others, it has a main impact on current plant production systems. Increasing areas of marginal soil are observed, but more and more people need to be fed. To fulfill some of the sustainable development goals (https://sdgs.un.org/goals) such as SDG2 Zero Hunger, SDG6 Clean Water and Sanitation, SDG12 Responsible Consumption and Production at least partially, the potential of plants need to be fully developed and exploited.

With this special section, we offer the opportunity to demonstrate how applied botany contributes to these goals. In general, every topic that uses botany to work towards the Sustainable Development Goals is welcome. We invite everyone to participate by submitting a manuscript until August 31, 2022!

This Special Section is connected to the Symposium "Applied Botany for Sustainability" at this year's International Conference of the German Society for Plant Sciences. Contributers to the symposium are also invited to submit their work as manuscript until August 31, 2022.

Antifogging additives for greenhouse covers - effects on phytochemicals and nutritional quality of lettuce

by Vanessa Harbart, Hans-Peter Kläring and Susanne Baldermann

Antifogging additives are commercially used in greenhouse films to prevent water droplet formation on these films. This can increase light transmission, and thus, improve crop yield. However, the effect of polytunnels with antifogging additives on phytochemical content in lettuce (Lactuca sativa var. capitata ) is currently unclear. Here, polytunnels were chosen as a model to investigate the impact of antifogging additives in a completely randomized setting. Analysis by means of chromatographic methods coupled with mass spectrometry revealed a general influence of polytunnel cultivation compared to lettuces grown without a polytunnel  ... read more ...

Influence of urban gardening conditions on the concentration of antioxidant secondary plant metabolites in kale

by Marie Bayer, Susanne Neugart and Tobias Pöhnl

During the COVID-19 pandemic urban gardening became popular across the globe. Leafy vegetables supplement the daily diet and contribute to consumers health. Within the last decade kale (Brassica oleracea var. sabellica L.) gained popularity in urban gardening. However, shading due to unfavourable cardinal directions may reduce plant growth and accumulation of health-promoting secondary plant metabolites such as polyphenols, carotenoids andglucosinolates in kale. We compared authentic urban gardening conditions for kale grown in all four cardinal directions of a residential building. The overall concentration of carotenoids did benefit from sun exposed growing locations, while concentrations of nutritionally important lutein did not differ ... read more ...

Mesembryanthemum crystallinum L. or iceplant is an annual facultative halophyte adapted to extreme environmental conditions, as salinity. This characteristic has special importance in the Mediterranean region, where the drought conditions entail the most important problems of soil and water salinity. Furthermore, there is currently a great gastronomic interest for this plant due to its soft texture, fresh and salty taste, high content of water and beneficial compounds for health. Therefore, the objective of this work was to establish the optimal salt growth conditions for pot cultivation of iceplant in greenhouse. Thus, the effect of different salinity levels (0, 100, 200 and 300 mM NaCl) under controlled conditions was evaluated.
Severe salinity treatments reduced crop production. However, results showed that the 100 mM NaCl treatment benefited plant growth. This treatment showed greater leaf fresh weight and area, pigment content and maintained its root and shoot biomass similar to control values. In addition, compared to control plants, salinity increased the specific leaf area and leaf relative water content, reduced leaf starch and K concentrations. Therefore, results confirm that iceplant pot culture can be strategically perform under low salinity conditions with an enhancement or maintenance of crop yield and quality.
