Pruning affects carbohydrate accumulation in the shoots and leaves of ‘Precoce de Tyrinthe’ apricot

Effects of environmental factors and management practices on microclimate, winter physiology, and frost resistance in trees

“…The effects of pruning depend greatly on the timing (summer vs. winter), although very few studies are available. Summer pruning may have no effect on NSC ( Usenik et al, 2008 ), or may promote NSC in different aboveground organs ( Den and Son, 2000 ; Demirtas et al, 2010 ). However, summer and winter pruning have positive synergistic effects on starch content the second year after treatment ( Den and Son, 2000 ), especially after fruit harvest ( Demirtas et al, 2010 ).…”

Changes in pruning frequency result in modifications in NSC distribution and seasonal patterns in ornamental species.…”

Effects of pruning intensity on the biochemical status of shoot buds in three mango (Mangifera indicaL.) cultivars planted at high density

“…It has also been proposed that pruning removes carbon pools and that the shoot promotes new leaf growth in order to increase carbohydrate reserves for the next flowering season (Sauco, 1996). The total sugars (TS) and sucrose contents of leaves increased after Winter pruning in apricot, but starch contents were always higher in non-pruned trees (Kuden and Son, 2000). Polyphenol oxidase (PPO) activities, and the contents of phenolic compounds, have a direct relationship with plant responses to many types of stress, including floral malformation in mango (Sharma et al, 2001;Sharma and Singh, 2006).…”
