| Objetivou-se caracterizar o crescimento inicial e as trocas gasosas de espécies de Spondias enxertadas sobre umbuzeiro. Foram realizadas avaliações de assimilação líquida de CO2 (A), condutância estomática (gs), transpiração foliar (E), teor de clorofila (Tcl), área foliar total (Aft), comprimento de ramos (Cr) e alocação de biomassa no sistema radicular e na parte aérea. As medidas de trocas gasosas foram realizadas entre as 9h e 11h da manhã sob céu limpo, em mudas com 60 dias após a enxertia, cultivadas sob 50% de sombreamento e irrigação diária. Umbuzeiro gigante e umbugueleira apresentaram as maiores taxas de A, em coerência com os maiores valores de Tcl, ao mesmo tempo que apresentaram os menores valores de gs e de E, indicando maior economia de... |

| Abstract: The objective of this work was to evaluate the chemical composition of 'Cabernet Franc' grape subjected to different levels of shoot topping. The experiment was conducted in the 2008 and 2009 vintages, and the levels of shoot topping consisted of: control, without topping; and reductions of 15, 30, and 45% in total leaf area. The effect of shoot topping intensity on the chemical composition of the 'Cabernet Franc' grape berries was observed. A reduction of 26% in the vegetative canopy through a moderate shoot topping increased the total polyphenol index and the anthocyanin content. Shoot topping is a practice that must be carried out with caution, since severe shoot topping, i.e., a reduction greater than 26% of the leaf area, may negatively... |

| The objective of this study was to evaluate the effect of bio-stimulant on the vegetative and reproductive aspects of dwarf-coconut over a period of 13 months in the state of Ceará. The experiment was conducted from September 2016 to October 2017, in a commercial production area, located in the municipality of Itarema, state of Ceará, using four-year-old plants, in a triangular spacing of 8 x 8 x 8 m in blocks at random, four doses of Crop-Set bio-stimulant plus control (0; 4; 8; 12 and 16 mL plant-1) with four replications. The Crop-Set bio-stimulant was applied through leaves with a back-pack spray, in the axilla of the ninth leaf of the coconut palm for 13 months. After its application, the number of leaves, flowers, fruits and bunches per plant was... |
