Fruit quality of Sicilian, commercially affirmed, and newly selected apple varieties: potential resources for genetic improvement and specialty marke…
2012
Several apple varieties are constantly selected for improved quality traits and introduced for cultivation and marketing in addition to a few traditional and affirmed varieties. Recently, specific fruit quality traits like enhanced flavor, crispness and juiciness have been particularly requested by consumers and are gradually replacing more conventional characteristics like fruit size, peel color and sweetness in the breeding programs. Furthermore, some of the newly selected varieties exhibit a relatively low level of plasticity, posing serious problems of adaptation when cultivation is proposed in a wide range of environments. In this most recent perspective, some of the old varieties or l…
Effect of rootstock vigor and in-row spacing on stem and root growth, conformation, and dry-matter distribution of young apple trees
2003
The effects of M.9 and MM.106 rootstocks and in-row spacing (0.4, 0.7, and 1 m) on the vegetative behavior of three-year-old apple (Malus domestica Borkh) trees were studied. Analysis of digital images was used to estimate canopy and root growth and conformation (shape and size), whereas dry matter distribution was used to determine partitioning to various plant parts. Trees on less vigorous M.9 rootstocks showed reduced stem and root growth as they produced less and/or shorter shoots and less and/or shorter and thinner roots. Canopy spread area (CSA) and volume were similar for trees on both rootstocks and differences in stem length density (stem length per unit canopy volume; SLD) compens…
