Phosphate Fertilization and Mycorrhizal Inoculation Increase Corn Leaf and Grai...
Buzo, F.S.; Garcia, N,F.S.; Gato, L.M.; Martins, I.M.B.; Martins, J.O.M.; Morita, P.R.S.; Silva, M.R.S.A.; Sales, L.Z.S.; Nogales, A.; Rigobelo, E.C.The agricultural use of arbuscular mycorrhizal fungi, such as Rhizoglomus intraradices, can increase the efficiency of phosphate fertilization for the benefit of the corn plant and grain nutrition. In this study, a field experiment was conducted in an area of Selvíria/MS, Brazil, in the years 2019 and 2020, to verify the effects of reduced doses of phosphorus combined with the inoculation of corn seed with R. i...
Response of Mycorrhizal ’Touriga Nacional‘ Variety Grapevines to High Temperatu...
Nogales, A.; Ribeiro, H.; Nogales-Bueno, J.; Hansen, L.D.; Gonçalves, E.F.; Coito, J.L.; Rato, A.E.; Peixe, A.; Viegas, W.; Cardoso, HéliaHeat stress negatively affects several physiological and biochemical processes in grapevine plants. In this work, two new methods, calorespirometry, which has been used to determine temperature adaptation in plants, and near-infrared (NIR) spectroscopy, which has been used to determine several grapevine-related traits and to discriminate among varieties, were tested to evaluate grapevine response to high temper...
Functional marker development from AOX genes requires deep phenotyping and indi...
Nogales, A.; Noceda, C.; Ragonezi, C.; Cardoso, Hélia; Campos, M.D.; Frederico, A.M.; Sircar, D.; Kumar, S.R.; Polidoros, A.; Peixe, A.The development of new ‘deep phenotyping’ techniques for functional markers (FM) development on alternative oxidase (AOX) gene sequences are expected to greatly increase the efficiency of association studies between the candidate FM sequences and the desired phenotype. However, it is critical to perform these studies in the appropriate target tissue/cell at the correct time point. AOX genes, due to their divers...
Confined crystallization in phase-separated poly(ethylene terephthalate)/poly(e...
Álvarez, C.; Nogales, A.; Garcia-Gutièrres, M. C.; Sanz, A.; Denchev, Z.; Fuinari, S. S.; Bruix, M.; Ezquerra, T. A.The isothermal cold crystallization of poly(ethylene terephthalate)(PET) in cryogenic mechanical alloyed blends of PET and Poly(ethylene naphthalene 2,6-dicarboxilate)(PEN) 1:1 by weight has been investigated by simultaneous small and wide angle X-ray scattering (SAXS and WAXS) and dielectric spectroscopy (DS). For transesterification levels higher than 23% the blends tend to transform into a onephase system an...
Relaxation Behavior of Poly(ethylene terephthalate)/Poly(ethylene naphthalene 2...
Denchev, Z.; Ezquerra, T. A.; Nogales, A.; Sics, I.; Álvarez, C.; Broza, G.; Schulte, K.A method including cryogenic grinding, melt pressing from the molten state, and quenching was used to prepare blends of poly(ethylene terephthalate) (PET) and poly(ethylene naphthalene 2,6-dicarboxylate) (PEN) in which the two phases were highly dispersed. The effect of melt-pressing times on the thermal properties and relaxation behavior of PET/PEN films were characterized with differential scanning calorimetr...
Simultaneous crystalline-amorphous phase evolution during crystallization of po...
Ezquerra, T. A.; Sics, I.; Nogales, A.; Denchev, Z.; Baltá-Calleja, F. J.Despite the fact that polymer crystallization has been the object of intense research, this process is far from being fully understood. Traditional polymer crystallization studies using X-ray scattering techniques mainly provide information about the ordered regions. To obtain a more complete information about the time evolution of both the crystalline and the amorphous phase during polymer crystallization, we ...
Induction time for cold crystallization in semi-rigid polymers: PEN and PEEK
Nogales, A.; Ezquerra, T. A.; Denchev, Z.; Baltá-Calleja, F. J.The appearance of long range density fluctuations in two isotropic semi-rigid polymers (PEN and PEEK), during the induction period prior to crystallization, when heating above the glass transition temperature, Tg, has been demonstrated by simultaneous wide- and small-angle X-ray scattering techniques. The parallel use of dielectric spectroscopy, to characterize the segmental dynamics of the amorphous polymers p...
