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.

Enhancement of biomass production, salinity tolerance and nutraceutical content of spinach (Spinacia oleracea L.) with the cuticular wax constituent triacontanol

by Bernat Tompa, Janos Balint and Laszlo Fodorpataki

The present study investigates the effect of foliar application of triacontanol (TRIA) on various physiological parameters with regard to crop yield and quality attributes of spinach (Spinacia oleracea L.) under normal growth conditions and salinity stress. Plantlets were grown for 21 days in perlite-containing pots supplemented with Hoagland’s nutrient solution, then they were subjected to 0 (control) or 150 mM NaCl. Two concentrations of TRIA (25 nM and 1 μM) were applied during seed germination and as foliar spray treatment, in itself or simultaneously with salt stress at 4-day intervals for three weeks. Exogenous application of TRIA enhanced germination energy and capacity, as well as ... read more

How harvest, cleaning and conservation good practices affect the quality of saffron: results of a research conducted in Italy

by V. Leoni, L. Giupponi, D. Pedrali, M. Zuccolo, G. Borgonovo, A. Bassoli and A. Giorgi

Saffron (Crocus sativus L.) spice making requires time-spending manual operations: stigmas are separated from the flower picked in bud early in the morning, and once dried they are preserved protected from light. This study verified how the correct pursuing of these good practices affects saffron quality. Few hours of exposure of the flower to the sun determined a significant decrease in the colouring strength (239.66 ± 10.33 versus 255.35 ± 11.87). The correct cleaning of stigmas determined a very significant increase of colouring strength (247.12 ± 13.32 instead of 224.35 ± 14.88) and a significant increase of flavour strength (99.72 ±7.48 against 90.31 ± 6.32, p <0.05). In 24 months, all the samples kept in the dark were still of first category of quality while the ones kept in the light dropped in second category. For all samples there was an increase of aroma strength and a decrease of the flavour and colouring strength, but only the colouring strength loss followed a significantly more sloping trendline. A detectable difference in the content of trans-crocin 4 correlated to the ageing or the way of conservation was not found, nevertheless, it was confirmed that the isomers tend towards a photostationary state where the trans isomer is more present.
