Gabriel,André; Resende,Juliano TV; Marodin,Josué C; Matos,Rafael de; Zeist,André R; Maciel,Cleber Daniel G.
ABSTRACT Brazil’s low garlic productivity is attributed, mainly to the lateral shoot growth, a physiological anomaly characterized by early lateral shoot growth of cloves in noble group garlic cultivars. Considering the aforementioned information, the aim was to evaluate the occurrence of lateral shoot growth and productivity characteristics in garlic plants, cv. Chonan, subject to herbicide chemical stress. In order to do so, an experiment was conducted in outlining randomized blocks in a 3x5 factorial scheme, constituted by three herbicides (paraquat 500 g ha-1; ammonium gluphosinate 400 g ha-1 and glyphosate 720 g ha-1) and five subdoses (0, 5, 10, 15 and 20% of the minimum recommended dose of each herbicide). The electron transport rates (ETR) were...

Production and quality of strawberry cultivated under different colors of low tunnel cover Horticultura Brasileira
Henschel,Juliane M; Resende,Juliano TV; Giloni-Lima,Patrícia C; Zeist,André R; Lima Filho,Renato B; Santos,Matheus H.
ABSTRACT Strawberry is a crop of great economic and social importance. Its fruits are appreciated both for their flavor and nutraceutical potential. Some studies confirm that light quality influences plant physiology. Thus, the aim of this study was to investigate if changes in light spectrum, provided by low tunnels, can improve vegetative traits, as well as, production and fruit quality of strawberry. The authors used six tunnel covers (red, yellow, blue, green, transparent and opaque and one control, without cover), and two cultivars: a short photoperiod cultivar (Camarosa) and a neutral photoperiod cultivar (Albion). Experiment was evaluated in two seasons: production and plant development first; and then, post-harvest quality. Overall, Camarosa showed...

Resistance of processing tomato genotypes to leafminer (Tuta absoluta) Horticultura Brasileira
Dias,Diego M; Resende,Juliano TV de; Zeist,André R; Gabriel,André; Santos,Matheus H; Vilela,Nathalia C.
ABSTRACT Tomato crop presents several obstacles that hinder its cultivation, especially the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae). To reduce damages caused by this pest, the development of resistant cultivars is one of the main alternatives. In this study we aimed to select tomato genotypes with high acylsugar contents and resistant to tomato leafminer. For this, contrasting F2RC1 genotypes for allelochemical contents, resulting from the interspecific cross between cultivar Redenção with processing characteristics, and the wild species Solanum pennellii accession ‘LA-716’, with high acylsugar contents, were submitted to a test of resistance to tomato leafminer with 14 treatments, being eight genotypes with high acylsugar content and...

Favaro,Renata; Resende,Juliano Tadeu V; Gabriel,André; Zeist,André R; Cordeiro,Ely Cristina N; Favaro Júnior,Jorge Luís.
ABSTRACT The strawberry is susceptible to several pests which cause a reduction in productivity. The use of mechanisms which repel or prevent these pests to establish, represent a sustainable environmental technology to reduce the frequency of agrochemical use. In this context, the aim of this study was to evaluate the effect of salicylic acid (SA) on resistance induction against two-spotted spider mite in strawberry cultivars (Aromas and Sweet Charlie). Five concentrations of SA (0, 25, 50, 75 and 100 mg L-1) were tested in order to verify the antixenosis effects. In SA concentration of 50 mg L-1, a reduced number of mites in the two strawberry cultivars was noticed. For the number of eggs deposited on leaflet, we verified an effect of SA concentration...
