Qualidade de sementes de tomate influenciada pelos tratamentos térmico e osmótico

Abstract: O tratamento térmico via calor seco, visando o controle de patógenos associado às sementes, pode causar danos à qualidade fisiológica das mesmas, que podem ser recuperados, por meio do condicionamento osmótico. Avaliou-se o efeito do tratamento térmico via calor seco na qualidade sanitária e fisiológica das sementes de tomate, assim como a influência do condicionamento osmótico na qualidade fisiológica das sementes submetidas à termoterapia. As sementes das cultivares Quadrado Mix, Topmec e Calmec VFN foram ex… Show more

“…In seeds, the elimination or reduction of the infective inoculant of fungi has been efficiently achieved through chemical, biological and physical treatments (ESTEFANI; MIRANDA FILHO; UESUGI, 2007). Among the physical methods, the effectiveness of thermotherapy, which consists of exposing the seeds to the action of heat combined with the time of treatment, has been demonstrated in some studies (CARMO et al, 2004;LOPES;ROSSETTO, 2004;OLIVEIRA et al, 2011). However, for this method to be successful, it is necessary to know the correct combination of temperature and exposure time, which may vary with the species, cultivar, batch, initial vigour and other factors.…”

“…Esse método não possui proteção residual na semente e pode afetar diretamente sua qualidade fisiológica. Também é importante analisar o binômio temperatura/tempo ideal para cada espécie (LOPES; ROSSETTO, 2004;MACHADO, 2000). Para o feijão, embora a termoterapia úmida por 30 min tenha sido eficiente para o controle de fungos fitopatogênicos, esse tratamento prejudicou o desempenho fisiológico das sementes.…”
