Ocorrência da podridão estilar em tomateiros (Lycopersicon esculentum Mill.) sob o efeito de reguladores de crescimento

Abstract: RESUMOEstudaram-se em condições de casa de vegetação os efeitos da aplicação de reguladores de crescimento na ocorrência da podridão estilar nos frutos de tomateiro cultivar "Miguel Pereira". Observou-se que ácido giberélico na concentração de 100 ppm promoveu alta incidência da anomalia fisiológica em plantas tratadas com altas dosagens de sulfato de amônio. Sob as mesmas condições, tomateiros pulverizados com ácido succínico -2.2-dim'tilhidrazida 4.000 ppm, cloreto de (2-cloroetil) trimetilamônio 2.000 ppm e… Show more

“…, but rather due to poor supply of Ca 2+ caused by reduced transport of Ca 2+ to the distal tissue of the fast growing fruit and also by an increased demand of the distal tissue for Ca 2+ by accelerating fruit expansion (Ho, 1998;Saure, 2005). In addition, a number of substances such as gibberellins (GA) (De Freitas et al, 2012a), abscisic acid (ABA) (De Freitas et al, 2014), ammoniacal fertilizers (Bar-Tal et al, 2001;Castro and Malavolta, 1976), together with environmental conditions such as water stress (Guichard et al, 2005), can modify this translocation, preventing Ca 2+ from reaching the fruit. Other factors affect the partition of Ca 2+ in plants, such as excessive rate of transpiration or even the lack of it, induced by high temperatures and/or low relative humidity.…”
