1. Initial Growth of Pinus taeda by Fertilization Response at Planting
ABSTRACT The objective of this study was to evaluate how the fertilizer composition, type and application method contribute to the initial growth of Pinus taeda applied at planting. Seedlings from an open-pollinated seed orchard of Pinus taeda were planted on a Humic Dystrudepts soil containing 15 treatments of fertilizer application at planting. Basal diam

2. Differences in volatile composition and sexual morphs in rambutan (Nephelium lappaceum L.) flowers and their effect in the Apis mellifera L. (Hymenoptera, Apidae) attraction
ABSTRACT We studied the volatile composition and sexual morphs of Nephelium lappaceum flowers from two orchards, and investigated the choice behavior of the honey bee, Apis mellifera toward the floral extracts from both locations. Our results showed significant differences in chemical composition and sexual morphs; only the hermaphrodite flowers from the Her

3. Thidiazuron (TDZ) increases fruit set and yield of ‘Hosui’ and ‘Packham’s Triumph’ pear trees
ABSTRACT The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. The exogenous application of thidiazuron (TDZ) and aminoethoxyvinilglycine (AVG) has shown promising results in some pear cultivars and other temperate fruit trees. The objective of this study was to evaluate the effect of TDZ and AVG on fruit set, yield,

7. Continuous usage of cover crops in citrus: influence in seedbank, weeds, and soils chemical characteristics / Uso contínuo de coberturas vegetais em citros: influência no banco de sementes, na comunidade infestante e nas características químicas do solo
In the last few years, the consumers, especially those of the external market, have become more and more interested in food security, namely on what it refers to the means of production. This fact has motivated the search for alternatives of low environmental impact, and one of these is the use cover crops or green manure. In this context the current researc

8. Evaluation of the insecticidal potential of natural and synthetic products in the control of the drills of graviola. / AvaliaÃÃo do potencial inseticida de produtos naturais e sintÃticos no controle das brocas da graviola.
Sour sop, Annona muricata, is an Annonaceae specie crop that is growing gradually in the Northeast region of Brazil. Although it is difficult to handle, considering the control of its diseases and pests that occur to it is one in such a way how much complicated, this fact does not intimidate the producers of pulps, ices cream, juices, therefore the promising

9. Substrates and nitrogen fertilization in the production of yellow passion fruit tree seedlings. / SUBSTRATOS E ADUBAÃÃO NITROGENADA NA PRODUÃÃO DE MUDAS DE MARACUJAZEIRO AMARELO .
The production of yellow passion fruit tree seedlings of high genetic, phytosanitary quality, well nourished and early is of outstanding importance both for taking on and for survival in the field. The development of the seedling depends on a few preponderant factors linked specifically to substrates and complementation with fertilizations. To try to minimiz

10. Variation in Male Fertilities and Pairwise Mating Probabilities in Picea glauca
Frequencies of multilocus male gametes in seeds collected from clones in several blocks of a white spruce seed orchard were analyzed as part of a 2-yr study of mating system variation in this species. Observed frequencies of male gamete types departed significantly from those expected assuming equal male fertilities among clones. Male gamete frequencies in s
