“…The increase in fruit dry weight through harvest for green table olives was approximately linear with the possible exception of slower growth in the first 15-30 DAFB. Such an expolinear growth pattern was first suggested for lightly-cropped fruit trees by Lakso et al (1995). A fairly linear growth pattern for fruit weight appears to be common in high-input, olive orchards even under greater crop loads (Trentacoste et al, 2010;Martín-Vertedor et al, 2011b).…”

“…This rather massive water exchange is central to the strategy developed by this species to accumulate fresh matter passively, yet in quantities larger than apple, on a whole fruit basis (DeJong and Goudriaan, 1989;Lakso et al, 1995). The main features of this strategy are the high permeability of the fruit epidermis and the full functionality of the xylem until harvest.…”

The relative contributions of xylem, phloem, and transpiration to fruit growth and the daily patterns of their flows have been determined in peach, during the two stages of rapid diameter increase, by precise and continuous monitoring of fruit diameter variations. Xylem, phloem, and transpiration contributions to growth were quantified by comparing the diurnal patterns of diameter change of fruits, which were then girdled and subsequently detached. Xylem supports peach growth by 70%, and phloem 30%, while transpiration accounts for ;60% of daily total inflows. These figures and their diurnal patterns were comparable among years, stages, and cultivars. Xylem was functional at both stage I and III, while fruit transpiration was high and strictly dependent on environmental conditions, causing periods of fruit shrinkage. Phloem imports were correlated to fruit shrinkage and appear to facilitate subsequent fruit enlargement. Peach displays a growth mechanism which can be explained on the basis of passive unloading of photoassimilates from the phloem. A pivotal role is played by the large amount of water flowing from the tree to the fruit and from the fruit to the atmosphere.

“…variation in initial deposit (Walklate et al 2003;Xu et al 2006), physical decay due to weather factors (Smith and MacHardy 1984) and growth dilution (Lakso et al 1995). The degradation of pesticide residues concentration due to the three processes has been approximately described by a first-order reaction model (Timme and Frehse 1980;Holland et al 1996).…”

A flexible and generic model was developed to predict the decline of residues of a non-systemic pesticide for both single and multi-spray situations as well as for different tree canopy zones. The model predicts not only the average residue levels, but also the confidence interval of the residues through either a deterministic or a stochastic approach. This generic model includes several key aspects of residue fates in the environment: initial deposit, physical loss and growth dilution. The model considers a tree canopy in three distinct zones for which initial deposition of pesticides may differ. In addition to predicting the average residue within each zone, it also estimates the 95 and 99% confidence intervals of residues on individual fruit within each zone. For the purpose of evaluation, this model was parameterized specifically for captan, one of the most important non-systemic fungicides used to control disease in horticultural crops. The observed average initial deposit for each zone was used in the evaluation. The overall correlation between predicted average residues and those observed on apple fruit in two applications was 0.93. Confidence intervals were also predicted accurately.
