dc.description.abstractThe source/sink relationship affects plant production and fruit quality in the field. This study aims to evaluate leaf and fruit traits of two field-grown blueberry cultivars as affected by variability of source/sink ratio (expressed as cm2 leaf area-to-fruit number ratio) at fruiting cane level. We found that range of source/sink ratio was larger in cv. Legacy than cv. Bluegold with no effect of season on this variable. There was a curvilinear increase of leaf dry mass-to-leaf area ratio (LMA) with source/sink ratio, which suggests that leaves acted as alternative carbon sinks to fruits. The relation between theses variable was no affected by cultivar. Mass-based nitrogen linearly decreased with source/sink ratio, while area-based nitrogen increased in curvilinear form by the effect of LMA. For leaf nitrogen values, a notable difference between cultivars was observed. Stomatal conductance (g<inf>s</inf>) dropped with increasing source/sink ratios with Bluegold achieving higher g<inf>s</inf> than Legacy for any given source/sink ratio. Dry (DW<inf>f</inf>) and fresh mass, diameter and total soluble solids (SS) of the fruit were related to source/sink ratio through curvilinear fit in both cultivars. The observed relations were similar between cultivars for DW<inf>f</inf> and SS, which suggest that the rate of the response of fruit carbon gain to changing source/sink ratios was conservative between the studied cultivars. Our results showed that fruit-bearing blueberry canes are semiautonomous regulating their resource allocation as function of source/sink ratio. © 2023 Elsevier B.V., All rights reserved.
