Autores: Coutinho, Pablo Wenderson Ribeiro; Echer, Márcia de Moraes; Guimarães, Vandeir Francisco; Lana, Maria do Carmo; Inagaki, Adriano Mitio; Brito, Tauane Santos; Alves, Thatiane Nepomuceno.
The objective was to evaluate the effect of calcium silicate on the chlorophyll content and gas exchange of two tomato hybrids. The design used was in randomized blocks in a 2x5 factorial scheme, with four replications. The first factor was composed of two tomato hybrids: Ivety and Natália, and the second factor was composed of five doses of calcium silicate (0, 150, 300, 450, and 600 kg ha-1), applied to the substrate before planting the seedlings. Gas exchange: net CO2 assimilation rate (A), leaf transpiration rate (E), stomatal conductance (gs), internal CO2 concentration (Ci), water-use efficiency (WUE), intrinsic efficiency water use (iWUE), and instant carboxylation efficiency (ACi); SPAD index and the levels of chlorophylls a, b, and total were...

INDUCED RESISTANCE AND Azospirillum brasilense AT THE CONTROL OF Bipolaris sorokiniana IN WHEAT AND INTERFERENCE ON DIAZOTROPHIC ENDOPHYTES
Provedor de dados: 22
Autores: Iurkiv, Luciana; Dildey, Omari Dangelo Forlin; Coltro-Roncato, Sidiane; Gonçalves-Trevisoli, Edilaine Della Valentina; Rissato, Bruna Broti; Guimarães, Vandeir Francisco; Stangarlin, José Renato.
The induced resistance eficiency in the control of phytopathogens is recognized, however little is known about its interference on non-target microrganisms. The present study aims to verify the induction of peroxidase activity by the use of acibenzolar-S-methyl (ASM), mannanoligosaccharide (MOS) and Bacillus cereus inductor in the control of spot blotch wheat disease and its interference on the non-target microrganism A. brasilense. The experiment was conduced under green house growing. The experimental design was made in randomized block design in a factorial schema 4 x 2 x 2, with 4 replications. The first factor "Resistance Inductors" was constituted by ASM, MOS, B. cereus inductors and water (control). The second factor "Pathogen" was constituted by...

Provedor de dados: 22
Autores: Dartora, Janaína; Echer, Márcia de Moraes; Guimarães, Vandeir Francisco; Marini, Deniele; Pauletti, Daiana Raquel.
The aim of this work was to evaluate, through the growth analysis, the effects of nitrogen doses on the development of Brassica campestris var. chinensis (Pak Choi). The experiment was carried out in a greenhouse, from October to November, 2007, in Marechal Cândido Rondon, Paraná. The experimental design was the randomized block, with five treatments (0, 60, 105, 150 and 195 kg ha-1 of N) and four replications. The hybrid used was Chouyou. The nitrogen was equally applied in three times, when in transplantation, and at seven and 14 days after the transplantation. The dry mass production, and the foliage area were weekly evaluated reaching the following indices of growth: relative and absolute growth rate, net assimilation rate, leaf area ratio, and...

Water status maintenance induced by Trinexapac-Ethyl in soybean plants
Provedor de dados: 22
Autores: Fioreze, Samuel Luiz; Guimarães, Vandeir Francisco.
Improving abiotic stress tolerance in plants by crop management is one of biggest goals of actual research, thus, plant growth regulators have a great potential in the physiological manure of crops. The objective of this work was to evaluate the effects of Trinexapac-Ethyl on soybean plants affected by drought stress during the reproductive stage. Four Trinexapac-Ethyl doses were evaluated (0, 50, 100, and 200 g ha-1 a.i.) and the induction or not of drought stress. The experimental design was completely randomized blocks in factorial design (4x2) with four replications. Relative water content was measured during drought stress and rehydration period. Protoplasmic tolerance and biometric parameters were determined after recovery period. Yield and yield...

Provedor de dados: 22
Autores: Dartora, Janaína; Guimarães, Vandeir Francisco; Marini, Deniele; Pinto Júnior, Artur Soares; Magalhães Cuz, Leonardo; Mensch, Reginaldo.
The aim of this study was to evaluate the interaction between the seed treatment with fungicides and insecticides and inoculation with Azospirillum brasilense and their effect on seed germination and early development of seedlings of maize and wheat. Two experiments were conducted with corn seeds and the other with wheat. The experimental design used in both trials was completely randomized design with four replications and treatments arranged in a 2x6 factorial, with the absence and presence of seed treatment and seed inoculated with different strains of A. brasilense: no inoculation, Ab-V5, Ab-V6, Hm53, SFO and IC26. In addition to the standard germination test (germination percentage int the first count and percentage of germination) were evaluated root...

Provedor de dados: 22
Autores: Bulegon, Lucas Guilherme; Meinerz, Cristiane Claudia; Castagnara, Deise Dalazen; Battistus, Andre Gustavo; Guimarães, Vandeir Francisco; Neres, Marcela Abbado.
Allelopathy is defined as the inhibitory or beneficial effect, direct or indirect, of one plant to another. Thus, it was conducted in the laboratory and under completely randomized design, a bioassay with the aim of evaluating the effect of aqueous extracts, obtained by infusion of dried leaves of oat (Avena sativa cv. IPR 126), pigeon pea (Cajanus cajan cv. Mandarin), ryegrass (Lolium multiflorum) and braquiaria (Brachiaria brizantha cv. Marandu), on the germination, content of cellular protein and peroxidase activity of lettuce (Lactuca sativa). The extracts of pigeon pea and oats reduced germination, which oats had higher allelopathic effect, delaying and reducing the emergence of lettuce seedings. To these treatments also was observed the lower...
