Grapes Autumn Royal

Description Grapes Autumn Royal

Seedless grape, late-ripening . In his pedigree varieties Blekrouz, Calmer, Alphonse Lavallée, Flame Seedless . Depending on the conditions vegetation and soil bushes growing in strength ranged from weak to medium growth . The clusters are large, weighing 800 g, some weighing up to2 kg . Berries are large from dark purple to black, average weight of 6.5 grams, one of the largest seedless grape varieties in the world . The skin is thin . For information on the behavior of the grapes in the promotion of a culture still under developments but vaccinations are needed in the area of the spread of phylloxera and nematodes . Recommended stocks: Harmony, Freedom, 5 C and 1103-P . Gradegrape well adapted to different types of soils, the recommended planting scheme 2 - 2,5 meters between the bushes, the aisles of 3.5 m . In the case of growth moderate spacing of the bushes can be reduced to 1.8 m . B is not sheltered zone recommended by the type of powerful formirovki four shoulder cordon pruning on a limb 2 - 3 buds, and leaving on the bush 28 - 32eye . crop quality depends essentially on the load vine . The optimal load can vary depending on soil and climatic conditions and the level of applied agricultural technology . The yield is high, but may be unstable over the years . The reason for this stage of the study but may be related to weather and climateconditions during differentiation fruitful kidneys . Class seedless high, but in some years, there are vestiges of grapes . The relatively weak attachment to the fruit stalk, which can lead to shattering berries in the maturity stage, putting covers on the cluster completely solves this problem, while protecting the grapes from wasps andbirds . In wet weather during the ripening berries can crack and rot . It is noted that treatment with gibberellin (group plant hormones that regulate growth) 2.5 - 5 g / ha in a phase of 80% - 90% bloom leads to a decrease number of berries in clusters (reducing density), increasing the size and weight of the berries, and in some seasons, reducing the number and sizerudiments . There was no decrease in fruitfulness in subsequent years when such treatments . Autumn Royal does not respond to treatment with gibberellin (group plant hormones that regulate growth) in the growth phase of berries, so that such treatment is not recommended . banding until tender berries can increase the size of 10 - 15%, but delayedstaining berries and ripening . With the use of banding weight of berries 7 - 7.5 g, with a full range of agricultural activities in t . h . gibberellin treatments (group plant hormones that regulate growth) berry weight can reach 10 - 12 g, size 26 x 35 mm, but in this case it is necessary to apply decimation of clusters to avoid excessiveseal berries in the bunch due to increasing the size of the berries .
