Special Issue Information

Dear Colleagues,

This Special Issue of Horticulturae is titled ‘Physiological Characteristics and Postharvest Quality of Fruit’ and is seeking high-quality manuscripts relating to fruit physiology and fruit quality.

The growth to maturity of fruit involves dramatic changes.  The main quality losses of fruit involve color, flavor, texture, and nutritional profile which relate to fruit physiology and biochemistry. Research in the postharvest field is crucial for the development of new technologies needed to extend shelf life, improve quality, and reduce food waste.

This Special Issue intends to gather information on postharvest treatments, postharvest fruit quality, as well as manuscripts considering juice quality as it relates to fruit quality or postharvest handling. Manuscripts in fruit physiology with an emphasis on metabolomics, transcriptomics, and genomics are also welcomed; however, any manuscript covering fruit physiology and postharvest quality will be considered for publication in this Special Issue.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Because of the vast information on health benefits and the urbanization impact changes in eating habits, the demand for ready-to-use shelled walnuts as a convenient, healthy, and nutritious snack food is increasing all over the world. However, shelled nuts sold as halves or pieces in ‘ready-to-use’ small packages are more susceptible to pellicle darkening and rancidity than their in-shell equivalents. Currently, about two-thirds of the USA crop is exported, and ~66% of these exports are sold as shelled ‘ready to use’, and its demand is increasing. Yet, this package style is generating quality challenges due to the darkening and rancidification of the kernel pellicle. Protection against kernel color quality loss and rancidity during postharvest handling, even at warm temperatures, can be accomplished at 6 kPa (%) oxygen or less for ‘Chandler’ and 3 kPa or less for ‘Howard’ and ‘Tulare’. The application of the ‘cold chain’ principle and/or low oxygen technology is unpractical for large cropping systems. Thus, a useful quality control system to rank the lots based on their potential visual and sensory quality is important. Then, the lots can be selected based on their potential quality, match market destinations, and are subjected to proper postharvest technologies. Full article

Plums are primarily marketed for fresh consumption, canning, freezing, jam and jelly. Unfortunately, plum consumption has remained steady or declined. Consumers complain about a lack of flavor quality but are willing to pay for higher quality. Thus, absence of flavor and cold storage disorders are the main barriers to consumption. Plum cultivars are sensitive to gel breakdown, flesh browning and ‘off flavors’. Consumer approval and postharvest life are controlled by genotype, quality attributes, harvest date and proper postharvest handling. A consumer quality index (CQI) based on soluble solids concentration (SSC) and minimum firmness is proposed to maximize flavor and postharvest life. In most cases, late harvest increases quality attributes. Our work and industry experience demonstrated that using critical bruising thresholds (CBT) based on minimum firmness measured at harvest acts as a reliable predictor of how late to harvest safely for maximum visual and sensory quality. Plums tolerated late harvest well because of their high tolerance to bruising damage, but suitable postharvest temperature management and selling within the potential postharvest life are required to maintain flavor and avoid the beginning of chilling injury. Thus, to maximize flavor and postharvest life, a CQI based on SSC and minimum firmness measured at consumption is proposed. This article provides guidance on using this CQI, combined with proper postharvest handling techniques, such as correct harvest date determination and temperature management, to maintain quality and increase consumption.
