“…It has been notified that endogenous ethylene was one of the important factors regulating the development of red colour and accumulation of anthocyanin in apples (Blankenship and Unrath, 1988;Whale and Singh, 2007). A disadvantage of inhibiting ethylene synthesis by AVG was reported as a delay in red colour development of apples (Greene, 2005;Argenta et al, 2006;Fallahi, 2007;Whale et al, 2008). The retarding impacts of AVG treatments on colour development values were also observed in the present study.…”

Cultural control of pre-harvest drop has relied upon plant growth regulators. To investigate the effects of plant growth regulators on pre-harvest drop and fruit quality, 150, 300 and 600 mg L -1 aminoethoxyvinylglycine (AVG) and 20 mg L -1 NAA were sprayed to 'Red Chief' apple trees at 4 week before anticipated harvest date. Untreated trees were kept as control. Results revealed that all AVG treatments increased the fruit removal force and significantly delayed pre-harvest drop and fruit maturity. Pre-harvest drop generally was unaffected by NAA. Internal ethylene concentration decreased with increasing AVG concentrations. Fruits treated with 150, 300 and 600 mg L -1 AVG showed increased fruit firmness and titratable acidity and reduced soluble solids content. Red colour development and starch degradation were retarded by all AVG treatments. Fruits treated with AVG (300 and 600 mg L -1 ) had lower fruit mass, fruit width and fruit length. The effect of NAA on all quality parameters was similar to the control treatment. AVG treatments decreased pre-harvest drop by fifty percent relatively to control.

“…Colour analysis was performed on each of the five commercial wakame samples and two New Zealand processed wakame (August and October samples from Farm 327) according to Whale, Singh, Behboudian, Janes, and Dhaliwal (2008) using a HunterLab ColorFlex machine. Each product was sampled three times and their means were compared using One-way ANOVA in Minitab 16.1.0 with Tukey's post hoc significance tests where p < 0.05 (a = 0.05) indicates a significant difference between means.…”

“…24 days before harvest) also induced a similar increase in exocarp color (?27%) but reduced fruit firmness by 19%, compared to the control. Again, ethephon is associated with advancing maturity by increasing color and softening fruit as in apple (Whale et al 2008) and blueberry (Vaccinium ashei, cv. rabbiteye) (Ban et al 2007).…”

Ethephon (2-chloroethyl phosphonic acid) is effectively used to promote development of the pedicelfruit abscission zone in tart cherry (Prunus cerasus) for mechanical harvest. Our research program is investigating the use of ethephon to promote pedicel-fruit retention force (PFRF) reduction on new sweet cherry (P. avium) cultivars to assist mechanized harvest and its affect upon fresh market quality fruit. Ethephon treatments were made at different timings and rates to 'Bing' and 'Chelan' during the 2006 season. Ethephon applications to 'Bing' trees more than 10 days prior to harvest were effective at reducing PFRF and facilitating mechanical harvest, irrespective of rate (1.2, 3.5, 5.8 L ha -1 [1, 3, 5 pt A -1 ]). Ethephon applied fewer than 10 days prior to harvest did not reduce PFRF sufficiently. In contrast, no rate or timing of ethephon studied induced a reduction in 'Chelan' PFRF sufficient for mechanical harvest. Accompanying PFRF analyses, fruit quality was assessed by measuring firmness (g mm -1 ), soluble solids (8Brix), weight (g) and color (CTIFL, scale 1-7). Ethephon applied 22 days before harvest at a rate of 3.5 L ha -1 enhanced exocarp color in 'Bing' by 27%, while reducing firmness in both 'Bing' (-19%, 22 days prior to harvest) and 'Chelan' (-15%, 20 days prior to harvest). We observed a significant natural decline in 'Skeena' PFRF to levels acceptable for mechanical harvest. This research documents genotypicspecific pedicel-fruit abscission characteristics and the potential to facilitate mechanical harvest of fresh market quality sweet cherry fruit using ethephon.
