Changes of Indole-3-Acetic Acid (IAA) Levels in The Flower and Fruit Abscission Periods on Washington Navel And Valencia Orange (Citrus sinensis L.) Cultivars Grown in Antalya Ecological Conditions

Abstract

In this study, changes of internal levels of indole asetic acid (IAA) in samples of both fallen and hanged (unfallen) fruits were investigated in full blossom (27th April, 2007) young fruits (25th May, 2007) and june drop (27th June, 2007) stages in Washington Navel and Valencia orange cultivars. Significant differences were detected among IAA levels when the sampling dates were considered. The least level of IAA was observed in extract representative of june drop 0,007 µg.g-1 while the values on this criterion were 0,076 µg.g-1 and 0,065 µg.g-1 for flowering and young fruit stages, respectively. Comparing the cultivars, differences among IAA levels were statisticaly significant. IAA level in Valencia was 0.077 µg.g-1 while it was 0.022 µg.g-1 for Washington Navel. When IAA levels were evaluated in terms of sampling dates of cultivars, significant differences were observed in cultivar x sampling date interactions. IAA levels in flowering and young fruit stages of Valencia cultivar were almost in unity with the value of 0,123 µg.g-1 and 0,097 µg.g-1 in order, while smilar levels of IAA were detected in june drop stage of Valencia 0.012 µg.g-1 and entire stages of Washington Navel (0.030, 0.033 and 0.003 µg.g-1, respectively). Changes in IAA levels with respect to developmental stages of cultivars were not found statictically significant. When IAA levels were evaluated in the drop and non drop flower and fruit, there were no significant differences. Fruit and flower IAA levels were found 0,043 µg.g-1 in drop and 0,056 µg.g-1 non drop samples.
