“…Nevertheless, stress at this stage also had adverse effects on shell development in some years, including distortion, breakdown, and a tendency for the thin, underdeveloped shells to split. Grierson et al (1982) cited various authors who showed that moderate stress can improve the quality of tree fruits and other crops. However, the extent of stress (severity and time of exposure) is critical.…”

“…Since macadamia trees have several characteristics that enable them to endure relatively dry conditions, stress at non-critical stages may not be reflected in depressed yields or inferior quality. In fact, Grierson et al (1982) document the beneficial manipulation of physiological stresses of various kinds, particularly those influencing ontogeny. By imposing mild water stress at appropriate, non-critical times, limited water resources could be reserved for critical phenological stages at which yield and/or quality would otherwise be adversely affected.…”

Abstract. Mild water stress was imposed on bearing macadamia trees in through-draining lysimeters at various phenological stages. Water was withheld until a xylem water potential (Ψ x ) of -1.5 to 2.0 MPa was reached, this being maintained by partial water replenishment at 2-day intervals. Flowering, nut set, nut development, yield, and quality responses were assessed to identify critical, stress-sensitive stages. Stress during nut maturation was particularly detrimental to both yield and quality, although stress during floral development and the premature nut drop also had adverse effects. Low yields were due to reduced nut number and smaller nuts. Lower photosynthesis (c. 2 µmol CO 2 /m 2 .s) at -1.5 MPa would account for reduced yield and poorer quality during nut maturation when energy demands of active oil accumulation are high. Stress at floral initiation was generally not detrimental.Overall, stress restricted growth. The rate of girth growth was significantly lower when stress was applied during the dormant floral initiation stage. When stress coincided with normal periods of vegetative growth, flushing was delayed until after re-watering when greater foliage production was stimulated. Judiciously imposing mild stress may be used to manipulate macadamia phenology, although it may not necessarily conserve water. Further refinement would be needed to develop stress manipulation as a practical and reliable management tool to achieve higher yields.Water should be applied to alleviate stress during critical stages of nut development and maturation. Mild stress after the current crop is mature, however, is unlikely to be detrimental to macadamia yield or quality. It may, in fact, be beneficial through manipulation of flushing patterns that influence yield.A R 0 2 1 0 8 M a c a d a m i a r e s p o n s e s t o mi l d w a t e r s t r e s s . R . A .

Chilling Injury: A Review of Possible Causes

Chilling injury has been defined as injury at temperatures low enough to cause damage but not cause freezing of water (17). Common usage refers to temperatures between 0° and 15°C, which cause irreversible damage to tropical and subtropical species. Except for the obvious postharvest loss of quality in many fruits and poor stand establishment in some field crops, the economic importance of chilling injury is difficult to quantify. Chilling injury often results in plants being “set back” so that maturation is delayed and yield reduced. A better understanding of the physiological and biochemical causes of injury and mechanisms of resistance will enable the horticulturist to design better cultural practices and the breeder to develop more resistant cultivars.

“…In addition, internal production of ethylene in stressed fruits was in quantities large enough to destroy chlorophyll in flavedo and enhanced color development. 22 Furthermore, cold weather (5-10°C) increased ABA level in "Valencia" oranges peel. 23 On the other hand, high temperatures prevented the breakdown of chlorophyll since chloroplasts remain in the flavedo throughout fruit development.…”

Many factors involved the regreening process of "Valencia" oranges under warm climate. Researchers focused on the difference between day and night temperatures in relation to the regreening process. This study paid a special attention to the branchbearing fruits whether its temperature or its nitrogen content before the regreening process till appearance of regreening. In addition, growth degree hours (GDH), which took into consideration the duration of effective temperature from sunrise to sunset considering the minimum degree as 13°C was also studied. Thus, the main objective of this study was to evaluate the role of the branch-bearing fruit temperature and nitrogen content on the regreening process during 2012 and 2013 seasons. The results proved that regreened "Valencia" fruits were growing on branches with greater nitrogen content, higher temperature and GDH. Furthermore, there were a high correlation between cumulative nitrogen content, temperature of branch-bearing fruits and GDH and the incidence of regreened "Valencia" oranges. Moreover, warm temperature throughout the season especially the period preceding harvest enhanced the uptake of nitrogen which reflected on more regreened "Valencia" oranges.
