“…Hence, almost all ovules were mature at the late balloon stage, but when lower temperatures occurring during pre-blossom months, most embryo sacs were immature at the late balloon stage. Abbott (1971) and Jackson et at. (1983) found that low temperatures during apple bud development period can, when imposed artificially, increase fruit set and that female flower fertility is involved.…”

“…A number of studies have shown a strong positive correlation between temperatures immediately following bloom in the field and fruit size at harvest (Abbott and Bull, 1973;Beattie and Folley, 1978;Blanpied and O'Kennedy, 1967;Green, 1981;Jackson and Hamer, 1980;Jackson et al, 1983;Lakso et al, 1995). In a few instances, attempts have been made to grow trees under modified environments in order to study these relationships in more detail.…”

Container-grown `Delicious', `Golden Delicious', `Braeburn', `Fuji' and `Royal Gala' apple [Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.] trees, on Malling 9 (M.9) rootstock, were subjected to a range of different maximum/minimum air temperature regimes for up to 80 days after full bloom (DAFB) in controlled environments to investigate the effects of temperature on fruit expansion, final fruit weight, and fruit maturation. Fruit expansion rates were highly responsive to temperature with those at a mean of 20 °C being ≈10 times greater than those at a mean of 6 °C. All cultivars exhibited the same general response although `Braeburn' consistently showed higher expansion rates at all temperatures compared with lowest rates for `Golden Delicious' and intermediate rates for both `Delicious' and `Fuji'. The duration of cell division, assessed indirectly by measuring expansion rate, appeared to be inversely related to mean temperature (i.e., prolonged under cooler conditions). Subsequently, fruit on trees from the coolest controlled temperature treatment showed greater expansion rates when transferred to the field and smaller differences in fruit size at harvest than would have been expected from the measured expansion rates under the cool treatment. Nonetheless, mean fruit weight from warm postbloom treatments was up to four times greater at harvest maturity than that from cool temperature treatments. Postbloom temperature also markedly affected fruit maturation. Fruit from warm postbloom temperature conditions had a higher soluble solids concentration, more yellow background color, lower flesh firmness, and greater starch hydrolysis than fruit from cooler temperatures.

“…In relation to tree performance and the effect of temperature before bloom, Beattie and Folley (1977), Abbot (1971), Jackson et al (1983), and Jackson and Hamer (1980), found adverse outcomes from higher pre-bloom temperatures (February, March, and April) on the fruit set, which may have affected flower quality and fertility. According to Abbot (1971), the temperature regime from the period of dormant to green cluster appeared to be as important as the period from green cluster to petal fall, as the higher temperatures in the second period are generally beneficial.…”

ing. For that, the mean, maximum, and minimum temperatures were used to describe weather during the autumns, winters, and early springs, for to be related with yield performance. Crop load-adjusted yield efficiency ranged between 10.1 and 6.8 kg m-2 PAR i , and fruit weight was found to be 134.4 g and 189.5 g among zones. The results showed that the crop load-adjusted yield and fruit size depended primarily on the maximum temperature during winter, and secondly, on season length (from bloom to harvest), with colder areas yielding better performance.
