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.

The region of Caborca, Sonora, Mexico, is one of the main area producers of table grapes, in particular the cultivar Red Globe. However, the main problems in the region include shortage and high cost of water, nematode infestation, and salinity. The objective of the present research was to determine the behavior of `Red Globe' cultivated on the rootstocks Harmony and Freedom. This study was carried out in the INIFAP Caborca research station in the year 2002, and consisted of 10 plants for treatment (on each rootstock). When water was low, a drip irrigation system was used. There was a completely randomized statistical design. We observed no differences among the two rootstocks in the different phonological stages (budbreak, flowering, and harvest time). The results indicated statistical differences between the rootstocks. Yield was higher on Freedom rootstock, with 2120 boxes/ha (boxes of 10 kg), an average of 470 boxes/ha more than on Harmony rootstock. Freedom rootstock also improved the quality of the grape (better color, bigger size of berry, and clusters, and the foliage was also more developed with this rootstock). In both rootstocks, nematode control was 100%, 30% in water consumption, and no fertilizer was used.

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.

Представлены экспериментальные данные о влиянии капельного орошения на урожайность и качество плодов томата при выращивании культуры в открытом грунте Московской области. На плодородных аллювиальных луговых почвах Москворецкой поймы при соблюдении агротехники без орошения в среднем за три года исследований в полевых условиях получена урожайность томата F1 Донской 31,9 т/га, с орошением 48,5 т/га, в т.ч. стандартной продукции 42,6 т/га.The article presents experimental data on the effect of drip irrigation on the yield and quality of tomato fruits when growing crops in open ground of the Moscow Region. On fertile alluvial meadow soils of the Moscow river floodplain, with the observance of agricultural technology without irrigation, the field yield of tomato hybrid F1 Donskoi on average for three years of research was 31.9 t/ha, with irrigation 48.5 t/ha, incl. standard production 42.6 t/ha.
