spp. Extracts as a Factor That Limits the Growth of spp. Bacteria, a Food Contaminant.

Due to their richness of bioactive substances, rose hips are a valuable raw material for obtaining extracts with potential antimicrobial activity. The aim of the study was to determine the antagonistic potential of whole pseudo-fruit and flesh extracts of three sp. varieties against spp.

The Effect of Supplementary LED Lighting on the Morphological and Physiological Traits of Miniature × 'Aga' and the Development of Powdery Mildew () under Greenhouse Conditions.

We investigated the growth traits, flower bud formation, photosynthetic performance, and powdery mildew development in miniature × 'Aga' plants grown in the greenhouse under different light-emitting diode (LED) light spectra. Fluorescence-based sensors that detect the maximum photochemical efficiency of photosystem II (PS II) as well as chlorophyll and flavonol indices were used in this study. Five different LED light treatments as a supplement to natural sunlight with red (R), blue (B), white (W), RBW+FR (far-red) (high R:FR), and RBW+FR (low R:FR) were used.

Apple Autotetraploids with Enhanced Resistance to Apple Scab () Due to Genome Duplication-Phenotypic and Genetic Evaluation.

Among the fungal diseases of apple trees, serious yield losses are due to an apple scab caused by . Protection against this disease is based mainly on chemical treatments, which are currently very limited. Therefore, it is extremely important to introduce cultivars with reduced susceptibility to this pathogen.
