Inhibition of sugarcane rooting by Ceratocystis paradoxa

Abstract

Sugarcane rooting was inhibited by Ceratocystis paradoxa on both pathogen-invaded setts and disease-free setts suspended above cultures of the fungus. Root inhibition was not correlated with differences in clonal susceptibility. Volatiles from cultures of the pathogen caused root inhibition and a concomitant rise in host-tissue production of ethylene. Apparently the host tissue is stimulated to produce ethylene both directly by tissue invasion and indirectly by fungal volatiles. The ethylene produced is then in part responsible for the observed root inhibition.

Antifungal Appraisal of Burkholderia Gladioli Strain Vimp03 (Jq867372) Against Ceratocystis Paradoxa

“…The C. paradoxa enters through cut ends and proliferates rapidly in parenchymal tissues of internodes developing brown-black cavities. It thus damages cane setts in the soil, inhibits rooting during the disease development, and affects juice quality by decreasing the level of sucrose and glucose [1][2][3].…”

Técnica cultural para o controle da podridão-abacaxi em cana-de-açúcar e modelo para estimativa de perdas

“…A inibição da brotação inicial dos toletes de cana-de-açúcar é causada, segundo BYTHER & STEINER (1970), pelo acetato etílico produzido por C. paradoxa. Altos níveis deste composto inibiu o enraizamento e quando isto ocorreu, foi detectado a presença de etileno.…”

Controle da podridão abacaxi da cana-de-açúcar por meio da pulverização de fungicidas em mudas no sulco de plantio

“…Em mudas submetidas à presença de acetato de etila exógeno, percebeu-se aumento na concentração de etileno, um inibidor de enraizamento. Assim, aparentemente os tecidos da cana-de-açúcar são estimulados a produzir etileno, em resposta à infecção por T. paradoxa ou por seus voláteis (BYTHER; STEINER, 1970;MOORE, 1974).…”
