light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...

The sustainability of reducing light in apple orchards under well-watered (ww) and water stress (ws) conditions was evaluated for relations, plant gas exchanges, fruit growth, yield determinants, quality over three years. A black (B) 28% shading net compared with two different 50% nets: red (R) white (W). Each combined irrigation regimes (ww ws) based on status. Under ww ws conditions, increasi...

ABSTRACT To reduce the risks associated with production of gladiolus flowers in climatic conditions southwestern Paraná, Brazil, this study characterized growth, development, and floral stem quality plants cultivated under different-colored shade nets mulching four growing seasons. The cultivar ‘White Goddess’ was grown beds without soil. Three individually stained black, silver red all 35% sha...

Quality seedlings production is one of the most important steps in cultivation vegetable species. In this sense, objective was to evaluate influence different environments and substrates on “pimenta-de-cheiro” (Capsicum chinense Jacq.) Boa Vista, Roraima. An experiment installed a completely randomized design (CRD), with treatmentsarranged subdivided plots. Five were evaluated: AG - agricultura...

The aim of this study was to determine the antimicrobial activity essential oils obtained from sweet basil (Ocimum basilicum L. cv. ‘Genovese’) cultivated in open field under different shading conditions (red, blue, and pearl nets with a shade index 50% full sunlight exposure (control plants)), harvested at times. (BEOs) all samples determined for four microorganisms, while determinations an ad...

Grid is one of the most e ective new paradigms in large scale distributed computing. Only recently Petri nets have been adopted as a formal modeling framework for describing the speci c aspects of the Grid. In this paper we describe a Grid tool for High Energy Physics data analysis, and we show how modeling its architecture with nets-withinnets has led us to identify and solve a number of defec...

The objective of this 2-year study (2017, 2019) was to evaluate the influence photoselective nets on apple fruit growth, focusing initial growth stages “Pink Lady”. Trees were subjected four (Blue, Red, White and Yellow) a standard black one (serving as Control), resulting in 5 light environments (LE), all shading at 20%. From 20 90 DAFB, 32 extension shoots, for each LE, measured total 11 time...
