Resumo: The combined effect of the antagonistic yeasts Rhodotorula aurantiaca LMA1, R. glutinis LMS and Pichia anomala CC-2 and silicon (Si) was evaluated in relation to the control of bacterial fruit blotch (Acidovorax citrulli) in seedlings and plants, and possible mechanisms of action involved in the control were analyzed. The incorporation of 1.41 g Si kg-1 (calcium silicate) into the substrate, together with foliar spraying with yeast (1.5 x 107 cells mL-1) and foliar spraying with 17 mM Si (potassium silicate) and the yeasts, separately or in combination, reduced the severity of the disease and protected seedlings and plants. These plants were inoculated with A. citrulli by foliar spraying (3.4 x 107 UFC mL-1) 24 h following the treatment. However, no additive or synergistic effects of the combined treatments were observed. The spraying of LMA1+Si and LMA1 resulted in the highest levels of control of bacterial fruit blotch in plants, and this level of control was higher than that provided by acibenzolar-S-methyl. Foliar spraying with LMA1 and Si, either separately or in combination, protected melon plants from infection by A. citrulli for 29 days. Increases in the activity of polyphenol oxidase (PFO) after foliar spraying with Si and LMA1, and increases of ascorbate peroxidase (APX) activity after foliar spraying with LMA1+Si and LMA1 are likely related to the induction of resistance to bacterial fruit blotch.

Dissertação (Programa de Pós-Graduação em Fitopatologia) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/6437The combined effect of the antagonistic yeasts Rhodotorula aurantiaca LMA1, R. glutinis LMS and Pichia anomala CC-2 and silicon (Si) was evaluated in relation to the control of bacterial fruit blotch (Acidovorax citrulli) in seedlings and plants, and possible mechanisms of action involved in the control were analyzed.

A incorporação de 1,41g Si kg-1 (silicato de cálcio) ao substrato e pulverização foliar com as leveduras (1,5 x 107 cels mL-1), assim como a pulverização com 17 mM Si (silicato de potássio) e leveduras, em combinação ou isoladamente, reduziram a severidade da doença, protegendo plântulas e plantas. As plantas foram inoculadas com A. citrulli por pulverização (3,4 x 107 UFC mL-1), 24 h após os tratamentos. No entanto, não foi verificado efeito aditivo ou sinergístico das combinações. A pulverização de LMA1+Si e LMA1 proporcionou os maiores níveis de controle da mancha aquosa em plantas, sendo superior ao acibenzolar-S-methyl. LMA1 e Si pulverizados em combinação ou não, protegeram as plantas de meloeiro da infecção por A. citrulli por 29 dias. Aumentos nos níveis das enzimas PFO pela pulverização de Si e LMA1 e APX por LMA1+Si e LMA1 estão provavelmente relacionados à indução de resistência a mancha aquosa.Submitted by (lucia.rodrigues@ufrpe.br) on 2017-02-17T15:11:31Z No. of bitstreams: 1 Claudeana Souza da Conceicao.pdf: 783432 bytes, checksum: fd59b60ffc3266d8d18f15005f8c14cc (MD5)Made available in DSpace on 2017-02-17T15:11:31Z (GMT).

description The combined effect of the antagonistic yeasts Rhodotorula aurantiaca LMA1, R. glutinis LMS and Pichia anomala CC-2 and silicon (Si) was evaluated in relation to the control of bacterial fruit blotch (Acidovorax citrulli) in seedlings and plants, and possible mechanisms of action involved in the control were analyzed. The incorporation of 1.41 g Si kg-1 (calcium silicate) into the substrate, together with foliar spraying with yeast (1.5 x 107 cells mL-1) and foliar spraying with 17 mM Si (potassium silicate) and the yeasts, separately or in combination, reduced the severity of the disease and protected seedlings and plants. These plants were inoculated with A. citrulli by foliar spraying (3.4 x 107 UFC mL-1) 24 h following the treatment. However, no additive or synergistic effects of the combined treatments were observed. The spraying of LMA1+Si and LMA1 resulted in the highest levels of control of bacterial fruit blotch in plants, and this level of control was higher than that provided by acibenzolar-S-methyl. Foliar spraying with LMA1 and Si, either separately or in combination, protected melon plants from infection by A. citrulli for 29 days. Increases in the activity of polyphenol oxidase (PFO) after foliar spraying with Si and LMA1, and increases of ascorbate peroxidase (APX) activity after foliar spraying with LMA1+Si and LMA1 are likely related to the induction of resistance to bacterial fruit blotch.
