| description | The paper presents the evolution of the formation and development of the pedunculate oak acorns during vegetation season. The study was conducted in two variants: variant control and variant flower / acorn isolated. Results showed that only 6.8% of the initial number of flowers have become mature acorns healthy to the control variant. The non-fecundated flowers represented 21%, but 65.2 % felt down in the different stages of the acorns development. From the carpophagus insects, Curculio glandium was that attacked 7% of the initial number of flowers. To the variant flower / acorn isolated, the healthy mature acorns constitute 13.8% of the initial number of flowers. As for the non-fecundated flowers and aborted acorns by the plant, they accounted 26.5% and 59.7%. |
