Dynamics of dry matter partitioning in young ‘Nocellara del Belice’ olive trees
2008
Dry matter partitioning of ‘Nocellara del Belice’ olive (Olea europaea L.) trees was assessed during one growing season. Four three-year-old potted trees from rooted cuttings trained to single-trunk free-canopy were destructively harvested at 30-day intervals during the growing season. The average dry matter increase was about 2 kg · year-1 per tree. Total plant dry weight increased linearly over the year, whereas root to shoot ratio followed a quadratic trend with its peak during winter. Dry matter of all canopy parts (trunk, branches, 1-year-old shoots, and leaves) increased linearly and leaves exhibited the fastest growth. Also fine roots accumulated dry matter over the year in a linear …
Vegetative and reproductive behavior of 'conference' and 'williams' pear trees trained to v-shape system
2007
V-shape systems represent an efficient and popular option to increase yields and fruit quality. Here we present a detailed study on canopy and root system growth and conformation, yields, fruit quality and dry matter partitioning of 'Conference' (C) and 'Williams' (W) pear trees trained to V-shape system. Digital images were used to determine total stem and root length, mean diameter and surface area; canopy and root system spread area, shape index and volume, canopy height and root depth. Dry weights were used to calculate dry matter partitioning. Stems of W trees were longer and thinner than those of C, which resulted in similar stem dry weights for the two cultivars, whereas root dry wei…
