Special Issue Information

Dear Colleagues,

This Special Issue aims to advance research into modern fruit growing. In modern fruit growing, the establishment and improvement of plantations to ensure relatively constant high fruit yields from one year to another, of superior quality, and in conditions of economic profitability, requires adequate conditions. Over the preceding decades, researchers’ attention on this topic has grown exponentially, as evidenced by the increasing number of scientific publications, especially those dealing with the quality of horticultural products. However, there are still open questions and challenges in this fascinating field, such as whether the density or intensity of planting can be impacted at metabolomic and genomic levels.

In this Special Issue, manuscripts (original research papers, reviews, mini-reviews, opinions, and perspectives) that focus on modern fruit-growing systems and their application for the improvement of fruit products quality are welcome. Topic may include, but are not limited to, biotic and abiotic stress, fruit quality, nutrition, cultivation, and postharvest periods at all levels. Transcriptome, proteome, and metabolome studies and assessments of biochemistry, fruit physiology, and development, fruit quality, grafting biology, flower development, and postharvest biology are most welcome.

Sincerely,

Dr. Aline Priscilla Gomes da Silva

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.

Global fruit and nut yields are affected by shortfalls in pollinator populations, and pollen limitation is most prevalent among tropical, bee-pollinated and self-incompatible plants. Macadamia is a subtropical, bee-pollinated crop in which some cultivars have been found to be highly outcrossing. We aimed to determine the extent of outcrossing and its effects on nut quality across a wide range of international macadamia cultivars in three countries. We sampled fruit from 19 macadamia cultivars across 23 sites in Australia, Brazil and South Africa. We used genotype-by-sequencing and MassARRAY methods to assign paternity to individual fruit and we assessed pollen-parent effects on nut quality. Macadamia was highly outcrossing, producing 80–100% of fruit by cross-pollination, at 17 of the 23 sites. Mixed mating (41–72% outcrossing) was identified at five sites, and low outcrossing (10%) was identified in one cultivar at one site where it was isolated from other flowering macadamia trees. Outcrossed fruit often had significantly better quality than selfed fruit, with 1.61–3.39 g higher nut-in-shell mass, 0.53–1.55 g higher kernel mass, 3.3–6.4% higher kernel recovery, and 3.0–3.5% higher oil concentration. The differences in kernel recovery equated to differences in value of USD 433–841 per ton of nut-in-shell at prices of USD 3000 per ton. In summary, macadamia cultivars were mostly highly outcrossing, and outcrossed nuts often had higher quality than selfed nuts. Growers should consider interplanting different cultivars more closely and distributing bee hives more widely to maximise cross-pollination, produce high yields, and optimise nut quality.
