Special Issue Information

Dear Colleagues,

In recent years, fruits have received increased interest as good sources of natural antioxidants and bioactive compounds. These biochemical constituents, which play a pivotal role in human nutrition and health, are an important source of vitamins, minerals, and other disease-fighting phytochemicals. In particular, fruit biochemical compounds are studied in epidemiological studies for their antioxidant and anti-inflammatory activities, with beneficial effects on human health, lowering the risk of cardiovascular diseases, diabetes, and cancers.

In this context, it is important to investigate the modifications occurring during maturity and how they affect tree and ripening processes post-harvest. In addition, a number of pre-harvest factors affect fruit quality, i.e. environmental conditions, genotype, rootstock influence, cultural practices and agronomic techniques, mineral nutrition, water supply, etc.

The items linked to the post-harvest management of fruit are topical factors that influence qualitative traits, i.e., cultivar, maturity stage, harvest period, and applied technologies (sorting and grading, packaging, storage conditions and transportation), during the post-harvest chain.

In light of the above statement, this Special Issue will extensively cover the topics of pre- and post-harvest factors, focusing on fruit physiology and biochemistry in order to maintain the overall quality of fresh produce. 

Kind regards,

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Horticulturae is an international peer-reviewed open access monthly journal published by MDPI.

Background: The implementation of advanced agronomical strategies, including the use of antitranspirant, in order to mitigate the negative effects of environmental stress, particularly heat stress on plants, has become a focal area of research in the Mediterranean basin. This region is characterized by hot and dry summer that affects plant physiology. Methods: The experiment was carried out in Sicily (South Italy) on 12-year-old avocado cv. Hass grafted onto Walter Hole rootstock. Two subplots each of forty homogenous trees were selected and treated (1) with calcium carbonate (DECCO Shield®) and (2) with water (control) at the following phenological phases: 711, 712 and 715 BBCH. The climatic parameters were recorded throughout the year. Physiological measurements (leaf transpiration, net photosynthesis, stomatal conductance, leaf water potential) were measured at 105, 131 and 168 days after full bloom. Fruit growth was monitored, and physico-chemical analyses were carried out at harvest. Results: The antitranspirant increased photosynthesis and stomatal conductance and reduced leaf transpiration (−26.1%). Fruit growth rate increased during summer, although no morphological and qualitative difference was observed at harvest. PCA highlighted the positive effect of the calcium carbonate on overall plant physiology. Conclusions: Antitranspirant foliar application reduced heat stress effects by improving physiological responses of avocado trees. Full article
