O feijão-caupi é uma das principais leguminosas cultivadas na região Nordeste, com finalidade direcionada para a produção de grãos secos ou vagens verdes. No entanto, essa sofre variações climáticas, sendo seca o principal fator estresse abiótico. Portanto, objetivou-se identificar as respostas morfológicas, fisiológicas e três genótipos feião-caupi: Pingo Ouro 1,2 (PO), Sempre Verde (SV) Feijão Moita (FM), submetidos ao hídrico severo seguido reidratação. Os tratamentos foram déficit (9...
The objective of this study was to characterize the phenology and determine harvest points snap bean varieties related degree-day accumulation. experiments were conducted in Teaching Garden Federal University Ceará, evaluating five genotypes. A randomized block design with three replications used for 1 2, respectively. Each experimental unit consisted a 9.6 m seedbed. In first experiment, spacing adopted 0.1 x 0.4 (24 plants per plot). For second 0.3 (32 Phenological characterization carried...
The cowpea is a legume that widely grown in the north-east of Brazil, and which has been gaining ground other regions country. main producer state Ceará, with large planted-area, albeit low productivity due to lack technology adapted cultivars. aim this study was identify recommend superior genotypes terms adaptability stability under rainfed irrigated conditions, addition reduced grain darkening. To end, six experiments were conducted different districts Ceará (Crato, Pentecoste, Crateús,...
Cultivating maize under systems of alley cropping results in improvements to the soil, a reduction weeds and an increase yield. Studies using ground cover from tree shoots produce similar results. The aim this study was evaluate effects on weed growth yield made up 30 t ha-1 (fresh matter) branches species: neem (Azadirachta indica A. Juss), gliricidia [Gliricidia sepium (Jacq.) Kunth ex Walp.], leucaena [Leucaena leucocephala (Lam.) de Wit.] sabiá (Mimosa caesalpiniifolia Benth.). Two...
ABSTRACT: This research studied the genetic control of traits related to melon fruit quality. The F1, F2, BC1, BC2 generations from OL x A-16 and PV crossings were evaluated in two separate trials conducted randomized blocks with three replications. were: average weight, shape index, pulp thickness, firmness, soluble solids content cracking rate. analyses accomplished through a classic study involving mixed models. parameters on heritability number loci controlling broad narrow sense....
The aim of this work was to evaluate the interaction between genotypes and environments, as well toindicate, for state Ceará, superior cowpea cultivars in terms adaptability, stability productivity dry grains. Theexperiments were conducted four different municipalities Ceará: Crateús, Madalena, Bela Cruz Limoeiro doNorte; two tests carried out Crateús (irrigated rainfed), totaling five assessment environments. experimental designused each assay randomized blocks with 12 replications....
Moisture correction of fresh pods cowpea genotypes has been used to correct weight differences from the same harvest. Correction is made by method soaking and grains in water. This study verifies need for moisture estimate yield production green grains. Sixteen were evaluated pod mass, grain hundred index, yield, two municipalities, Pentecoste Marco, Ceara State, Brazil. For correction, a sample ten was collected, weighed, soaked Samples weighed until constant wet mass. Subsequently, samples...
Bird attacks on the sunflower may hinder its exploitation in Brazilian semi-arid region.The aim of this study was to evaluate effects different levels protection (0, 33, 66 and 100%) capitula eight cultivars, evaluated randomized blocks with sub-divided plots four replications.The cultivars were allocated sub-plots, by covering caps non-woven fabric after physiological maturity.The most frequent bird species Paroaria dominicana.The Aguará 06 cultivar productive tolerant attack, followed...
Objetivou-se com este trabalho, avaliar a eficiência da utilização de diferentes coeficientes similaridade na estimação diversidade genética Jatropha curcas L. utilizando marcadores moleculares ISSR. O DNA genômico foi extraído partir folhas jovens 43 acessos pinhão-manso. Matrizes dissimilaridade foram obtidas dos Baroni, Coincidência Simples, Hamann, Índice II, III, Jaccard, Nei e Li, Ochiai I, Rogers Tanimoto Sokal Sneath. Os dendrogramas construídos o método UPGMA comparados mediante os...
ABSTRACT This study aimed to evaluate the efficiency of phosphorus use with melon genotypes cultivated in a hydroponic system. Ten were evaluated solutions and without restriction. A randomized block design 10 × 2 factorial scheme was used, five replicates. The following characteristics evaluated: leaf number, stem diameter, main branch length, root system volume, chlorophyll, shoot concentration ratio, total phosphorus, dry matter matter, use, acquisition, internal utilization efficiencies....
A cultura da bananeira ( Musa spp.) é de extrema importância para a região semiárida do Brasil. No entanto, fatores edafoclimáticos, como seca, contribuem redução produtividade. Algumas técnicas monitoramento através sensoriamento remoto vêm auxiliando produtores no manejo propriedade. Objetivou-se com este trabalho, estimar Produtividade Primaria Bruta (PPB) vegetação nativa e cultivo irrigado bananeira, na Cariri Cearense, remoto. O experimento foi realizado em área localizada sul estado...
ABSTRACT The main quality parameters of melon are related to sucrose accumulation and soluble solids content. Understanding the genetic control these traits is essential help breeders in selection process. aim this study was evaluate inheritance content melon. A randomized block design with three replicates used AC-16 Vedrantais parents, F1, F2, BC1 BC2 generations. We verified that factor which environmental variability observed sugar between parents. involves a major effect gene additive...
Abstract The objective of this work was to determine the inheritance beta-carotene content in melon (Cucumis melo). AC-16 accession melo subsp. var. acidulus) – with a low and white mesocarp crossed Vedrantais cultivar (C. cantalupensis) high salmon colored –, obtain F1, F2, BC1, BC2 generations. 'Vedrantais' parents, F1 F2 generations, BC1 backcrosses each parent were evaluated. quantification carried out high-performance liquid chromatography system. Mean components related additive...
In recent years, there has been a growing interest in sustainable agricultural production, aimed at cleaner with less soil degradation, pollution control and greater social responsibility. this sense, the objective of present study was to evaluate biometry productivity different cultivars pumpkins (Cucurbita moschata) cultivated managements. The experiment carried out an area located municipality Acarape, Ceará, where two cultivation systems were used, they were: conventional alleys three...
