Abstract
decay caused by C. gloeosporioides (cid:133)(cid:145)(cid:143)(cid:146)(cid:131)(cid:148)(cid:135)(cid:134)(cid:3)(cid:150)(cid:145)(cid:3)(cid:24)(cid:25)(cid:486) AI due to the induction of endogenous JA accumulation and the up-regulation of PR genes. The crosstalk between JA and ethylene may also play a role in the defense mechanism against pathogen infection in apple fruit. infected with C. gloeosporioides . These results suggest that the increases in bioactive sub-(cid:149)(cid:150)(cid:131)(cid:144)(cid:133)(cid:135)(cid:149)(cid:3) induced after irradiation with UV-C. UV-C irradiation may enhance the synthesis of secondary metabolites associated with the inhibition of pathogen infection. Furthermore, our study also revealed that UV-BI increased DPPH antioxidant
期刊介绍：
eJHS publishes original research articles and reviews on significant plant science discoveries and new or modified methodologies and technologies with a broad international and cross-disciplinary interest in the scope of global horticulture. eJHS focus is on applied and fundamental aspects of the entire food value chain, ranging from breeding, production, processing, trading to retailing of horticultural crops and commodities in temperate and Mediterranean regions. In particular eJHS emphasizes integrated crop management strategies during the preharvest and postharvest stages, aiming at sustainably increasing the quantity and quality of horticultural products. The eJHS publishes peer-reviewed articles, reviews and special thematic issues in the following science areas:
breeding and genetic resources;
clonal (micro)propagation and seed physiology;
cropping systems, including crop management practices;
plant/fruit growth and development, including interactions with environments and organisms;
plant protection and plant nutrition;
irrigation and plant water relation;
whole plant physiology and source/sink relation;
urban horticulture/protected cultivation;
fruit ripening and product quality;
storage technologies, including postharvest disorders;
food processing technologies/horticultural engineering;
marketing/economics;
education and consultancy;
consumer sciences.
