Effect of Aminoethoxyvinylglycine (AVG) on Preharvest Drop, Fruit Quality, and Maturation of `McIntosh' Apples. II. Effect of Timing and Concentration Relationships and Spray Volume

Abstract: AVG was evaluated for its effect on controlling preharvest drop and infl uencing ripening of 'McIntosh' apples in Maine and Massachusetts. AVG consistently and effectively retarded preharvest drop. AVG was superior to NAA and comparable to daminozide in drop control. Dilute or 2× applications were more effective than applications made at lower water volumes. One application of AVG made 4 weeks before anticipated normal harvest was more effective in controlling preharvest drop than split applications of the sam… Show more

“…AVG decreases ethylene biosynthesis by inhibiting aminocyclopropane-1-carboxylic acid synthase (ACC) synthase (ACS), one of the two key enzymes in the ethylene biosynthesis pathway (Kende, 1993;Yu and Yang, 1979). Preharvest AVG treatment suppressed ethylene production, reduced fruit drop, and delayed fruit ripening in apples (Autio and Bramlage, 1982;Bangerth, 1978;Bramlage et al, 1980;Child et al, 1984;Greene and Schupp, 2004;Halder-Doll and Bangerth, 1987;Salas et al, 2011;Schupp and Greene, 2004;Whale et al, 2008) and peaches (Prunus persica) (Bregoli et al, 2002;Ziosi et al, 2008). The response of pears to AVG has received less research attention.…”

“…Reduction of fruit internal ethylene concentration as a consequence of AVG preharvest spray application has been shown in fruit trees (Belding and Lokaj, 2002;Greene and Schupp, 2004;Schupp and Greene, 2004) as well as in melons (Shellie, 1999). However, in the latter study with melons, no apparent positive effect of AVG spray (125 gÁha -1 a.i.)…”

“…either 18 or 12 DBH, it delayed the development of fruit abscission zone, and that AVG-treated melons had lower ethylene production at harvest and after cold storage. Generally, AVG is applied as preharvest spray in peaches, apples, and melons (Belding and Lokaj, 2002;Greene and Schupp, 2004;Schupp and Greene, 2004;Shellie, 1999) or as a fruit dipping after harvest (Byers, 1997). The effectiveness of AVG when applied to the root zone is unknown, but there is some speculation that AVG can be rapidly taken up by roots and translocated to the rest of the plant (Valent BioSciences Corp., Libertyville, Ill, personal communication, 2000).…”

“…The ability of AVG, as ReTain, to enhance pecan fruit retention is consistent with similar effects on certain walnut (Juglans regia L. cv. Serr) cultivars (Anderson et al, 2006;Beede and Polito, 2003;Buchner et al, 2006) and certain other tree or vine fruit crops (Belding and Lokaj, 2002;Bregoli et al, 2002;Byers, 1997Byers, , 1998aByers, , 1998bClayton et al, 2000;Dal-Cin et al, 2008;Greene, 2002Greene, , 2005Greene, , 2006Greene and Schupp, 2004;Hayama et al, 2008;Hu et al, 2002;Rath et al, 2006;Salazar-Garciìa et al, 2006;Schupp and Greene, 2004;Shafer et al, 1997;Webster et al, 2006;Williams, 1980). The product may therefore exhibit potential as a horticultural tool for crop load management in pecan (Wood et al, 2009).…”
