“…Normally, the stress on the plant caused by any environmental factor can lead to an initial reduction in YII125 and in Fv/Fm, linked to impaired functionality of the photosynthetic apparatus (Kramer et al, 2004). The maximum efficiency photochemical efficiency of the FSII or the FV / FM ratio is a sensitive indicator of the photosynthetic performance of plants, with values ranging from 0.75 to 0.85 (Wagner & Merotto Junior, 2014). In plants not supplemented with Si and kept at 50% WRC, Fv/Fm values were below optimal, evidencing impairment of the photosynthetic apparatus during water drought.…”

“…A redução da taxa de transporte de elétrons pode ocorrer a partir de 96 horas após a aplicação de glyphosate (ZOBIOLE et al, 2011;WAGNER;JÚNIO, 2014). Essa redução está diretamente ligada com a diminuição da taxa fotossintética e por consequência da condutância estomática, taxa de transpiração e eficiência no uso da água (Figura 4 e Figura 5) que são dependentes do transporte de elétrons no fotossistema II.…”
