摘要:
The present work aimed to evaluate the agronomic performance of the seedless grape cultivar Sugraone on four rootstocks in the Sao Francisco Valley. The trial was carried out in a commercial vineyard in Sento Se, State of Bahia for four seasons (2002 to 2004). The treatments were four cultivars of rootstock ('Paulsen 1103', 'SO4', 'Harmony' and '420A'), using a randomized block design. The highest yield per plant and vegetative vigor were obtained on the rootstock Paulsen 1103. Also there was a tendency for higher mass of bunches, mass and size of berries on the same rootstock, although there were variations between seasons. The rootstock showed positive influence on the content of soluble solids, but did not affect the total acidity and TSS/TA. Young plants of grapevine cv. Sugraone showed good agronomic performance on Paulsen 1103, but it is important to continue the studies for a larger number of years to recommend their use in the Sao Francisco Valley.
