Conteúdo:  The aim of this study was to identify the correlation between photochemical efficiency and candidate genes expression to elucidate the drought tolerance mechanisms in coffee progenies (Icatu Vermelho IAC 3851-2 x Catimor UFV 1602-215) previously identified as tolerant in field conditions. Four progenies (2, 5, 12 and 15) were evaluated under water-deficit conditions (water deficit imposed 8 months after transplanting seedlings to the pots) and under irrigated system. Evaluations of physiological parameters and expression of candidate genes for drought tolerance were performed. Progeny 5 showed capacity to maintain water potential, which contributed to lower qP variation between irrigated and deficit conditions. However, the increases of qN and NPQ in response to stress indicate that this progeny is photochemically responsive to small variations of am protecting the photosystem and maintaining qP. Data obtained for progeny 12 indicated a lower water status maintenance capacity, but with increased qN and NPQ providing maintenance of the PSII and ETR parameters. A PCA analysis revealed that the genes coding regulatory proteins, ABA-synthesis, cellular protectors, isoforms of ascorbate peroxidase clearly displayed a major response to drought stress and discriminated the progenies 5 and 12 which showed a better photochemical response. The genes CaMYB1, CaERF017, CaEDR2, CaNCED, CaAPX1, CaAPX5, CaGolS3, CaDHN1 and CaPYL8a were up-regulated in the arabica coffee progenies with grea... Mostrar Tudo

Título:  Are artificial semi-dry wetlands efficient in wastewater treatment from different fish densities and for lettuce production?
Ano de publicação:  2021
Fonte/Imprenta:  International Journal of Environmental Science and Technology, Oct. 2021.
DOI:  https://doi.org/10.1007/s13762-021-03703-6
Idioma:  Inglês
Conteúdo:  This study aimed to determine artifcial semi-dry wetlands' performance to wastewater treatment from fish farming and Lactuca sativa production in an aquaponics system. This trial model observed the effects of different stocking biomass on the growth rate of Colossoma macropomum and yield of two L. sativa varieties. A factorial design consisting of three fish density treatments in quadruplicate and two Lettuces variety was used. Nine hundred and sixty fingerlings with 8.35±0.91 g were stocked at three stocking biomass treatments in quadruplicate: 40 fingerlings or 334 g m-3; 80 fingerlings 668 g m-3; 120 fingerlings or 1002 g m-3. Delice American Lettuce and Purple Crested Lettuce were cultured in the semi-dry wetlands. The fnal mass (g), consumed food, feed conversion ratio, and yield of fngerling were statistically diferent between the tested densities, but survival did not. The artificial semi-dry wetlands were efcient on water treatment and the recovery of nutrients in all fsh densities trials, and it has potential as support for lettuce production. The recovery of nutrients was shown on the increment of the number of leaves, total fresh mass (g), and lettuces yield by area (kg m-2) in both varieties of plants tested. Precocious fowering in 30% of lettuce varieties, incidence of mealybug and whitefly, temperature and defciency of calcium and magnesium were factors that may have compromised the full lettuce development. The aquaponics system eficiently treated the fsh efue... Mostrar Tudo
