The Effect of Aminoethoxyvinylglycine (AVG) and Napthalene Acetic Acid (NAA) on the Preharvest Drop and Fruit Quality in Monreo Peach Variety
Öz
This study was carried out to increase the fruit quality and reduce preharvest drop of Monreo peach
variety. For this purpose, 150 and 225 mg L–1 aminoethoxyvinylglycine [(AVG) (4 weeks before the anticipated
harvest date)] with 10 and 20 mg L–1 napthalene acetic acid [(NAA), 2 weeks before the anticipated harvest
date] were sprayed to the trial trees. In the study, pre-harvest drop and some fruit quality parameters [soluble
solids content (SSC, %), pH, fruit flesh firmness (kg), titratable acidity (TA, g malic acid 100 mL-1) and fruit
color characteristics (L*, C*, h°)] were determined. AVG treatments was found to be different in significant level
(P<0.05) than NAA treatments and control with respect to reducing pre-harvest drop at the anticipated harvest date.
AVG and NAA positively affected the SSC of fruit. In general, the pH was reduced towards the anticipated harvest
date. The flesh firmness was linearly reduced towards the anticipated harvest date, but it was positively affected by
increasing AVG doses
