ABSTRACT: The coconut cultivated area has greatly increased in the Federal District Region of Brazil for the last five years. However, the crop management is still poor on seedling production. Therefore, the improvement of production methods has been highly demanded by coconut growers. Coconut seeds (fruits) should be collected from a superior genetic material and the seedlings should be vigorous, of pest and disease free and well established. The first step is the appropriate age to harvest the fruits, 11 to 12 months after opening the spathe. There is no difference in germination rate for no cutting or cutting on basal position of the fruits before sowing them. Cutting is less adopted by growers, and no cutting seems to be more practical and less time-consuming. Types of sowing systems: the traditional method, where fruits are left to geminate in seedbed, carried out to nurseries and then to the field. In the alternative method, the fruits are kept in the vertical position with a density of 15 to 20 nuts/m2. Four months later the seedlings are taken directly to the field. This placement of fruits is highly recommended because it avoids breaking of basal part of the stem and takes less time for seedling production, resulting in a better seedling establishment in the field. An adequate orchard management, especially regarding to irrigation and fertilization, is a very important practice to improve productivity, earlyness and fruit quality. The equilateral triangle is the recommended spacing type, since it allows higher penetration of light in the coconut canopy. The objective of this work was determine seedling production method for Federal District Region, and to suggest appropriate practices for establishment of coconut orchard in the field.

Conteúdo: |
Inferencias geneticas sobre o desempenho de cinco cultivares de tomateiro (Angela I. 5100, Floradade, IPA-05, Jumbo AG-592 e Santa Clara) e seus p(p-1)/2 hibridos dialelicos foram obtidas com base em tres caracteristicas de producao e quatro caracteristicas relacionadas a qualidade dos frutos, empregando-se a metodologia de Hayman (1954). Os resultados evidenciaram a possibilidade de ganhos geneticos relativos as caracteristicas de producao. O mesmo nao ocorreu com os teores de solidos soluveis, carotenoides totais e betacaroteno. Isto denota a reduzida variabilidade nas caracteristicas da qualidade dos frutos avaliados. |
