It is clear that training branches of the variety Cox’s Orange Pippin to the horizontal results in better fruit set. Trials indicate that the horizontal orientation is important not just to flower development but to the success of …
Research at Long Ashton showed that management of apple trees that results in excessive growth of bourse or extension shoots can reduce fruit set ( Abbott, 1960 ). The reasons for this are probably primarily associated with competition between the shoots …

Deciding whether to reduce the crop load (by thinning or other methods) It is important to maximise yields of apples in the grades most desired by the markets in order to sustain reasonable profitability. Maximising fruit set and total yields is rarely …
Mature and well-managed apple trees develop approximately similar numbers of spur and extension leaves in each season. These leaves are vital for producing, by photosynthesis, the food stuffs (sugars, carbohydrates) that power the growth of the fruits. It …
The traditional practice in fruit thinning is to thin to either one or two fruits per flower cluster. On sites which regularly produce heavy crops of smallish fruits, thinning to single fruits per cluster is usually recommended. On more fertile sites, or …
