Plant spacing and pollen quantity on yield and quality of squash seeds
Provedor de dados: 75
Autores: Lima,Márcio S. de; Cardoso,Antonio I. I.; Verdial,Marcelo F.
Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen...

Autores: Souza,Francisco I. de; Grangeiro,Leilson C.; Souza,Valdívia de F. L. de; Gonçalvez,Francisco das C.; Oliveira,Fábio H. T. de; Jesus,Priscila M. M. de.
ABSTRACT The objective of this research was to evaluate the agronomic performance of Italian zucchini as a function of phosphate fertilization. The experiments were carried at the Rafael Fernandes Experimental Farm, Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil, from August to November 2015 and from July to September 2016. The experimental design was randomized blocks in 2 x 5 factorial scheme, with four replicates. The treatments consisted of the combination of two cultivars (Caserta and Alícia) and five doses of phosphorus (0, 40, 78, 120 and 150 kg ha-1 of P2O5). Phosphorus doses associated with the maximum marketable yields estimated were smaller for Alícia than for Caserta in the period from August to November 2015. In the...

Irrigation depths and yield response factor in zucchini cultivation
Provedor de dados: 91
Autores: Azevedo,Benito M. de; Fernandes,Carlos N. V.; Vasconcelos,Denise V.; Garcia,Amparo C.; Figueredo Júnior,Luis G. M. de; Viana,Thales V. de A.
ABSTRACT The objective of this study was to evaluate the effect of different irrigation depths on productive performance and yield response of zucchini (Cucurbita pepo L.). A field trial was carried out in the experimental area of ​​the Meteorological Station of the Federal University of Ceará, CE, Brazil. The experimental design was randomized blocks, with six treatments and four replicates. The treatments adopted were: 30, 60, 90, 120, 150 and 180% of the reference evapotranspiration (ETo), estimated by Penman-Monteith (EToPM) and applied by drip irrigation. Fruit weight, number of fruits, fruit length, fruit diameter, pulp thickness, soluble solids and yield were analyzed, as well as water use efficiency (WUE). The methodology proposed by FAO Bulletin...

Potassium fertilizer applied by different methods in the zucchini crop
Provedor de dados: 91
Autores: Fernandes,Carlos N. V.; Azevedo,Benito M. de; Camargo,Débora C.; Dias,Chrislene N.; Rebouças Neto,Mario de O.; Costa,Fellype R. B.
ABSTRACT Aiming to evaluate the effect of potassium (K) doses applied by the conventional method and fertigation in zucchini (Cucurbita pepo L.), a field experiment was conducted in Fortaleza, CE, Brazil. The statistical design was a randomized block, with four replicates, in a 4 x 2 factorial scheme, which corresponded to four doses of K (0, 75, 150 and 300 kg K2O ha-1) and two fertilization methods (conventional and fertigation). The analyzed variables were: fruit mass (FM), number of fruits (NF), fruit length (FL), fruit diameter (FD), pulp thickness (PT), soluble solids (SS), yield (Y), water use efficiency (WUE) and potassium use efficiency (KUE), besides an economic analysis using the net present value (NPV), internal rate of return (IRR) and payback...

Extracción asistida por microondas de lípidos de las semillas de Cucurbita pepo L. (calabaza)
Provedor de dados: 98
Autores: Salomón Izquierdo,Suslebys; Bermello Crespo,Addiss; Márquez Conde,Tania; López Hernández,Orestes D; González Sanabia,María L; Llópiz Yurell,Julio C.
Introducción: los lípidos presentes en las semillas de Cucurbita pepo L. ricos en ácidos grasos poliinsaturados han demostrado tener acción antiinflamatoria en la hiperplasia prostática benigna. El empleo de la energía de las microondas en la extracción de compuestos de origen natural tiene como ventaja principal, la rapidez del calentamiento, que permite significativos ahorros de tiempo y en consecuencia energía en el proceso, todo lo cual se manifiesta en una reducción de los costos en general. Objetivos: estudiar el efecto del tiempo en la obtención de los lípidos contenidos en las semillas de Cucurbita pepo L. mediante la extracción asistida por microondas. Métodos: se estudiaron diferentes tiempos (1, 5, 10 y 15 min) para extraer los lípidos de las...

Evaluación del extracto lipofílico de Cucurbita pepo L. sobre la hiperplasia prostática inducida por andrógenos
Provedor de dados: 98

El aceite de semillas de calabaza ha sido ampliamente utilizado en el tratamiento de la hiperplasia prostática. En el presente trabajo se estudió el efecto del extracto lipofílico de semillas de Cucurbita pepo L (ELMSC) en el modelo in vivo de hiperplasia prostática experimental inducida por propionato de testosterona durante 15 días. Se observó que el ELMSC a las dosis de 400 y 200 mg/ kg provocó una disminución significativa del crecimiento prostático. Nuestros resultados indican que el ELMSC a dosis mayores de 200 mg/ Kg inhibe el crecimiento prostático inducido por la testosterona en el modelo experimental de hiperplasia prostática en ratas.
