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...

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...

Marodin,Josué C; Resende,Francisco V; Resende,Juliano TV de; Gabriel,André; Zeist,André R; Constantino,Leonel V; Sanzovo,Alisson WS.
ABSTRACT Studies on the interaction between garlic plant density and virus-free seed size are scarce in Brazil. Thus, this study was installed to evaluate the effect of plant spacing and seed size on garlic traits and yield for infected and virus-free bulbs. Treatments were arranged in a randomized block design and 2x5x3 factorial combination [infected and virus-free bulbs, five plant spacings (210, 260, 300, 360, and 390 cm2 per plant), and three bulbous seed sizes (sieve one, two, and three)]. The highest bulb yield was observed for virus-free seeds at a plant spacing of 390 cm2 plant-1, while the highest commercial yield was verified for 210 cm2 plant-1 spacing. The combination of virus-free seeds, larger bulbs, and 332 cm2 plant-1 spacing promoted the...
