Special Issue Information
Dear Colleagues,
Managing source–sink relationships is important to ensure yield and fruit specifications are sustained. Fruit production systems have changed and intensified; we now have smaller trees that require fewer inputs and are more easily suited to mechanised practices. Similarly, vineyards are managed to balance seasonal vegetative growth, contributing to the grape quality. Using cultivars and rootstocks is crucial for advanced orchard and vineyard systems to sustain and enhance fruit production. Climate change and variability influence these systems by changing source–sink relationships and, consequently, fruit quality.
Research enhancing our understanding and management of source–sink relationships in advanced viticulture and horticulture production systems is very welcome. This includes studies on tree and vine balance, seasonal carbohydrate and nutrient dynamics, as well as the allocation and translocation of these to the roots, canopy, and fruit development. Using technology to monitor these developments facilitates informed decision making for managing trees and vines.
Cultivar and rootstock selection are important contributions to optimise source–sink relationships, but both can be substantially affected by environmental conditions. Therefore, the challenges of climate change in this context will be strongly considered for this 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. Agronomy 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 2600 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.
