Abstract
Pesquisou-se durante seis anos o comportamento reprodutivo de cinco novas seleções de pêssego e nectarina em Monte Alegre do Sul (22°41'S; 46°43'W e 40 HF-7). Os pessegueiros e nectarineiras cultivados nos espaçamentos de 4 x 0,5m e 4 x Im, equivalentes a 5000 e 2500 plantas/ha, respectivamente, foram podados drasticamente, a cada dois anos, após a colheita. Em ambos espaçamentos,'Aurora-2* e IAC 282-24 apresentaram as melhores produções acima de 19 toneladas/ha. Verificou-se nos ciclos subseqüentes a cada poda da copa, tendência de menor produção das plantas, principalmente em material de ciclo mediano. No segundo ano após a poda drástica, os pessegueiros e nectarineiras produziram normalmente. No espaçamento de 4 x 0,5m, as plantas apresentaram acréscimo médio de 12% na produção, em relação a 4 x lm, diminuindo porém, o peso do produto final. Os maiores frutos com peso médio acima de l00g foram produzidos pelas seleções IAC 6782-83 e IAC 282-24.
Five new peach and nectarin selections were grown under the meadow orchard system, with bienal drastic pruning, at 4m x 0.5m and 4m x lm spacings. The experimental area was located in Monte Alegre do Sul, (22°41'S; 46°43'W and 40 hours below 7°C) State of São Paulo, Brazil. Results obtained during the six years of experiments clearly indicate that the 'Aurora-2' and IAC 282-24 peach selections were the best, with an average yield above 19 ton per hectare. For 4m x 0.5m spacing, with a density of 5000 plants per hectare, the productivity increased about 12%, however decreasing the weight of the final product. The best average weights of the fruits, above of l00g, were obtained by the IAC 6782-83 and IAC 282-24 selections.
