“…Considering the growth of water sprouts, it appeared that the stage of bud development was not mature enough for flower bud initiation in those water sprouts that stopped their extension growth later than mid-August. Induction of flower buds is governed by hormonal balance, especially by the level of gibberellins (Luckwill, 1974;Sedgley, 1990). In this study, we sampled the apical 10-cm segment of the sprouts where flower primordia are differentiated.…”

Heavy pruning to lower tree height of persimmon results in excessive production of water sprouts and reduced yield. This experiment was conducted on ‘Fuyu’ (Diospyros kaki) trees to assess if the time for terminal bud set of water sprouts affected flower bud formation. Some sprouts were not pruned to serve as fruiting branches for the next season. Thirty to 40 water sprouts were tagged in 2005 and 2006, the growth of which stopped from mid-June to late August. The later terminal buds set, the lower the percent dry weight in the apical 10 cm. The apical segments of sprouts that continued to grow to mid- to late August were characterized by low soluble sugars, starch, and inorganic elements such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) compared with those that set terminal buds earlier. The number of flower buds from the water sprouts that set terminal buds by early August the previous year bore more than 12 flower buds the next year, whereas those that grew to mid- to late August bore fewer than three. It was concluded that water sprouts could be used as fruiting branches for the next year as long as terminal buds set by early August, thereby alleviating yield reductions that come with heavy pruning.

“…The physiological age of the leaves near the apex varies widely depending on the time of terminal bud set. Environmental conditions, including light and temperature during late summer (Buban and Faust, 1982;Jackson and Sweet, 1972;Sedgley, 1990), may be another factor causing hormonal changes that affect flower bud formation.…”

“…In response to this lack of chilling, advances have been made with the breeding of lowchill cultivars and the development of chemical rest breaking agents and other orchard management practices to induce bud break (Sedgley, 1990). Similarly, defoliation prior to endodormancy of apple grown in the tropics will induce a second crop (Janick, 1974).…”

“…But requirements vary considerably: for example, Prunus (almond) has a very low chill requirement (100-500 hours), whilst Malus has a wide range (200-1,500+ hours). To overcome the lack of chilling, low-chill cultivars were bred along with the development of chemical and orchard management practices to induce bud break (Sedgley, 1990). However, it is highly unlikely that such cultivars would be suitable for the distinctive UK climate or be acceptable to UK consumer palates.…”

The impacts of climate change for UK fruit growing regions requiring winter chill dormancy are discussed and insights are drawn from subtropical regions where chilling requirements for these perennial crops have been overcome. A further challenge facing UK soft fruit growers is water availability for irrigation. To maintain future productivity, more sustainable production systems are needed. The authors discuss recent advances in irrigation scheduling and deficit irrigation techniques, along with their potential to reduce water inputs while maintaining yields of high-quality, healthy berries.
