Gibberellins have been strongly implicated in the growth of fruits. Many gibberellins have been identified in the seeds of apple fruits ( Hedden et al ., 1993 ). Soon after anthesis (first opening of the flower), high concentrations of the active …
After fruit set, the growth of the persisting fruitlets is brought about by a combination of cell division and cell expansion. Research undertaken many years ago showed that the majority of cell division ceases within 4 weeks of pollination ( Bain and …
Apple fruits grow by cell division and cell expansion. Most cell division occurs in the first 3‑4 weeks following fruit set and by 7 weeks cell division has almost finished. Thereafter, fruits grow by the cells expanding. The best large fruits, in terms …
It is important to that reducing crop loads not only improves the final fruit size of apples. At lower crop loads, the apples are often of improved quality; they ripen earlier, are sweeter, often firmer and have higher levels of dry matter. Work conducted …
Warm temperatures in the 4 to 6 weeks after fruit set will have a very beneficial effect in encouraging cell division in the young developing fruits. Such conditions will also aid the development of bourse and extension shoot leaves which will begin to …
Ensure that fruitlets set with adequate numbers of seeds Optimise crop loading by judicious thinning of flowers and/or fruitlets Climatic conditions in the first month after fruit set Prune and train trees so as to optimise exposure of fruits to light and …
Prune and train trees so as to maintain a balance of flowering spurs and new extension shoot growth. Lack of new growth, as may be experienced with trees of dessert varieties on M.27 rootstock, leads to high yield productivity but poor fruit size and …
Use of training systems which expose fruitlets to the full sunlight, such as Tatura or other trellis systems will also improve cell division. Prune and train trees so as to optimise exposure of fruits to light and achieve good colour development In UK …
If fruitlets are to expand and develop into high quality large fruits at the time of harvest it is essential to maintain adequate supplies of water and nutrients to the tree throughout the growing season. Irrigation The influence of different amounts and …
If fruitlets are to expand and develop into high quality large fruits at the time of harvest it is essential to maintain adequate supplies of water and nutrients to the tree throughout the growing season. Water needs are estimated using calculations of …
