This study aimed to evaluate the physiological responses to environmental stress during pre- and post-harvest of the following banana cultivars: Prata (AAB), Japira (AAAB) and Vitoria (AAAB). Analyses were carried out on young plants at vegetative stage (daughter-plant) and adult plants at reproductive stage (motherplant). The experimental design was completely randomized. In the in vivo pre-harvest analysis were used seven replications, in a factorial scheme (3x2x2), three cultivars and two stages (vegetative and reproductive) and two collection periods (March and June). For the analysis of post-harvest quality were used five replications in a factorial design (3x2x5), corresponding to three cultivars, two development stages and five periods of post-harvest analysis,
carried out every two days from stage 4 of fruit ripening. The chlorophyll a fluorescence emission kinetics showed low photochemical performance of the three cultivars in June, a period characterized by lower temperatures and water deficit. Prata was the cultivar with the lowest tolerance to abiotic physiological behavior changes, which also reflected in fruit quality, because there was a change in physical and physicochemical parameters. Japira and Vitoria cultivars showed similar physiological responses in the pre- and post-harvest periods, according to their phylogenetic proximity. The total performance index, i.e., the conservation of energy absorbed by PSII up to the reduction of the final PSI acceptors (PItotal) and the di-malonic aldehyde (MDA) content were significantly higher in Japira and Vitoria cultivars compared to Prata cultivar in the reproductive phase. There was no significant
change in the potential quantum efficiency of PSII (FV / FM = jP0) among the three cultivars. It was concluded that Japira and Vitoria cultivars showed greater plasticity to tolerate or even adapt to abiotic variations keeping higher fruit yield. PItotal is the most sensitive parameter during the banana life cycle and important tool for distinguishing different cultivars yields.

Foram realizadas avaliações da incidência e severidade da ferrugem e mancha-de-olho-pardo em 55 clones de café Conilon (Coffea canephora Pierre ex Froenher), nos experimentos regionais
localizados em Marilândia e Sooretama, no norte do Estado do Espírito Santo, tendo como testemunhas a variedade clonal do produtor (VCP) e a variedade de semente (VS). Em Sooretama, o experimento foi conduzido sob condições de sequeiro e de irrigação. A ferrugem ocorreu em 20% dos clones em Marilândia, com maior severidade nos clones 02 e 143. A mancha-de-olho-pardo ocorreu com maior severidade em Sooretama em condições de sequeiro, sendo os clones 4+8, 14, 45, 99 e 106 os mais suscetíveis. Em condições de irrigação, a ferrugem ocorreu com maior severidade nos clones 154, 11, 76/1 e 25+8, e apenas 5,5% dos genótipos avaliados não apresentaram sintomas. Nos dois ambientes, 69% dos clones foram resistentes à ferrugem e 1,8% dos clones não apresentaram sintomas da doença. |
