Seedless Grape

Gibberellins have been used to improve quality of grapes in several cases. However, gibberellic acid (GA) alone is not enough to improve the quality in Perlette. A field experiment was conducted on 3-year-old grape cv. Perlette trained on pergolas, to investigate the effect of bunch dipping with GA3 and N6-benzyladenine (BA) on reducing the problem of shot berries and improving the productivity of grapevines. Our observations proved that the stage of application of GA3 and BA is crucial to avoiding seed formation in seedless varieties such as Perlette for table grapes. The results showed that BA at low (10 µL/L) or high concentration (30 µL/L) at 50% of full bloom caused seed development in the seedless grape cv. Perlette, whereas no seed was formed when BA was used later at the fruit set stage. Based on our studies, we found that bunch dipping with 30 µL/L GA3 (at 50% of full bloom) and 10µL/L BA (at pea size) significantly reduced the problem of shot berries, and improved the yield and quality in grape cv. Perlette.

Our observations proved that the stage of application of GA3 and BA is crucial to avoiding seed formation in seedless varieties such as Perlette for table grapes. The results showed that BA at low (10 �L/L) or high concentration (30 �L/L) at 50% of full bloom caused seed development in the seedless grape cv. Perlette, whereas no seed was formed when BA was used later at the fruit set stage. Based on our studies, we found that bunch dipping with 30 �L/L GA3 (at 50% of full bloom) and 10�L/L BA (at pea size) significantly reduced the problem of shot berries, and improved the yield and quality in grape cv.

This study was conducted during the period 2006-2008 in the Faliszowice Vineyard in the Sandomierz Upland. The experiment evaluated yield quality of 'Einset Seedless' grape after the application of gibberellic acid (GA<sub>3</sub>) in the form of the growth regulator Arbostim 100 SL and 2-naphthoxyacetic acid (NOA) in the form of the growth regulator Betokson Super 050 SL. These growth regulators were applied during flowering by spraying the inflorescences or immersing them in whole at the following concentrations: 100 mg×L<sup>-1</sup> GA<sub>3</sub> - the treatment was performed once at full flowering (70-80% of open flowers); 50 mg×L<sup>-1</sup> GA<sub>3</sub> - the treatment was performed twice: at the beginning of flowering (20% of open flowers), and the second time at the end of flowering (80% of faded flowers); 50 mg×L<sup>-1</sup> GA<sub>3</sub> + 0.2% NOA - the treatment was performed once at full flowering; and 0.2% NOA - the treatment was performed once at full flowering. The study showed that the applied treatments had a beneficial effect on cluster and berry weight as well as on the number of berries per cluster in the grape variety 'Einset Seedless'. Gibberellic acid and the mixture of 50 mg×L<sup>-1</sup> GA<sub>3</sub> and 0.2% NOA were shown to have a significant effect on cluster and berry length; an exception were clusters and berries sprayed with 50 mg×L<sup>-1</sup> GA<sub>3</sub> whose length did not differ significantly compared to the control ones. The applied treatments slightly affected berry width in the grape variety under study. The growth regulators applied were found to have an adverse effect on extract content in 'Einset Seedless' fruit.

Succinic acid-2,2-dimethylhydrazide (SADH) did not improve berry set of Himrod and de Chaunac grapes; (2-chloroethyl) trimethylammonium chloride (CCC) improved berry set of both cultivars but had deleterious effects on berry quality. Gibberellic acid (GA3), applied as a post-bloom spray, increased set and reduced acidity of Himrod grapes.
