Do chitosan and its derivatives have the same protective effect on drought-contrasting maize genotypes? An analysis of physiological and production processes. Authorship: REIS, C. O. dos; MAGALHAES, P. C.; AMBROSIO, A. dos S.; ALMEIDA, L. G.; CARVALHO, D. T.; SOUZA, T. C, de Water stress is among the most severe abiotic stress factors for maize production. The application of chitosan causes various responses in plants, as a function of its structure and concentration. The... ... Repository: BDPA Publication year: 2022
Foliar application of potassium nitrate induces tolerance to water deficit in pre-flowering sorghum plants. Authorship: ÁVILA, R. G.; MAGALHAES, P. C.; SILVA, E. M. da; ALVARENGA, A. A. de; REIS, C. O. dos; CUSTÓDIO. A. M.; JAKELAITIS, A.; SOUZA, T. C. de The objective of this study was to evaluate the the ability of foliar application of potassium nitrate (KNO3) to induce water deficit tolerance in sorghum plants (Sorghum bicolor cv. P898012) subjecte... ... Repository: BDPA Publication year: 2022
Root system of maize plants cultivated under water deficit conditions with application of chitosan. Authorship: ALMEIDA, L. G.; SILVA, E. M. da; MAGALHAES, P. C.; KARAM, D.; REIS, C. O. dos; GOMES JÚNIOR, C. C.; MARQUES, D. M. Low water availability is regarded as an abiotic stress that limits the agricultural production. Due to the physical and chemical characteristics of chitosan (CHT), this substance might stimulate phys... ... Repository: BDPA Publication year: 2020
The foliar application of a mixture of semisynthetic chitosan derivatives induces tolerance to water deficit in maize, improving the antioxidant system and increasing photosynthesis and grain yield. Authorship: RABELO, V. M.; MAGALHAES, P. C.; BRESSANIN, L. A.; CARVALHO, D. T.; REIS, C. O.; KARAM, D.; DORIGUETTO, A. C.; SANTOS, M. H. dos; SANTOS FILHO, P. R. dos; SOUZA, T. C. de Research has shown that chitosan induces plant stress tolerance and protection, but few studies have explored chemical modifications of chitosan and their effects on plants under water stress. Chitosa... ... Repository: BDPA Publication year: 2019
Action of N-succinyl and N,O-dicarboxymethyl chitosan derivatives on chlorophyll photosynthesis and fluorescence in drought-sensitive maize. Authorship: REIS, C. O. dos; MAGALHAES, P. C.; AVILA, R. G.; ALMEIDA, L. G.; RABELO, V. M.; CARVALHO, D. T.; CABRAL, D. F.; KARAM, D.; SOUZA, T. C. de Chitosan induces plant tolerance to various abiotic stresses, including water deficit. However, its use may be limited, due to its constitution and low solubility in water. Thus, chemical modification... ... Repository: BDPA Publication year: 2019
