Emergência E Crescimento Inicial De Melancia Submetida a Salinidade E Doses De Ácido Salicílico

Abstract: A melancia é uma olerícola relevante para o Brasil, inclusive para a região Nordeste. No entanto, a sua produção é afetada pelo excesso de sais na água de irrigação dessa região. O ácido salicílico é uma substância que vem sendo utilizada como mitigadora dos efeitos desses estresses sobre as plantas. Assim, objetivou-se avaliar o tratamento de sementes com ácido salicílico como atenuante da salinidade sob o crescimento inicial de melancia. O experimento foi conduzido em delineamento em blocos casualizados, com… Show more

“…Thus, cell division and elongation are impaired, preventing growth and greater accumulations of plant biomass. A similar effect was also observed in watermelon, whose seedling dry mass was reduced with increasing salinity of irrigation waters (Silva et al, 2015;Nóbrega et al, 2020). On the other hand, the mode of action of salicylic acid stands out, because it is related to secondary plant metabolism and the production of metabolites that help in mitigating the osmotic effects caused by the stresses.…”

“…This fact may be related to the mode of action of gibberellic acid, which acts as initiator of germination and mobilization of reserves (Tsegay and Andargie, 2018). In addition, gibberellins in the seeds may interact with salicylic acid, which is involved in the plant's defense system, both against herbivory and abiotic stresses (Nóbrega et al, 2020).…”

O AS também possui a função de elevar o potencial produtivo das culturas(SILVA, 2012).Todavia, até o momento, pouquíssimos estudos foram realizados objetivando esclarecer a relação do ácido salicílico com a qualidade de sementes de soja, especialmente, quando submetidas à condição de estresse do envelhecimento acelerado.METODOLOGIAO trabalho foi conduzido no Laboratório de Agropecuária do Instituto Federal do Piauí -Campus Uruçuí.…”
