The effect of water deficit was determined on both in vitro and soil seedling as well as in cells in suspension of Agave americana *** order to do the establishment of cells,the formation of callus was induced;for it two auxins were evaluated:2,4-dichlorophenoxyacetic acid(2,4-D)and 4-mino-3,5,6-trichloropicolinic acid(picloram)at three concentrations(0.25,0.5 and 0.75 mg l−1)in three explants(leaf,root and meristems)cultured in MS semisolid *** callogenesis response was related to the type and section of the explant,as well as the regulator used,and a cell suspension was established using 0.5 mg l−1 naphthaleneacetic acid(NAA)+0.5 mg l−1 Benzylaminopurine(BAP).Seedlings were exposed to polyethyleneglycol(15%and 30%w/v)with a water potential of−0.87 and−2.67 MPa,respectively,under soil *** stress was applied through restricted *** weight,root system growth,and chlorophyll concentration were some of the parameters that were affected by the effect of water deficit on *** *** concentration values were significantly decreased by 15 at 30%PEG(19.6 SPAD units)compared to the control *** in vitro plants,the highest concentration of proline was found in the roots,being the treatment with 30%polyethylene glycol where the highest concentration of this osmoregulator was obtained(62.5 mg g−1 DW).Under restricted irrigation conditions,an increase in proline concentration was observed both in the aerial part(2.2μg 100 g−1 DW)and in the root system(1.8μg 100 g−1 DW).However,the concentrations found were approximately ten times greater,less than those found under in vitro ***,the accumulation of proline can be considered an indicator of stress in Agave Americana *** in vitro.

luminescence Characteristics of laAlO<sub>3</sub>:Eu<sup>3+</sup>Obtained by Modified Pechini’s Method

引用

Open Journal of Synthesis Theory and Applications 2017年第1期6卷 1-12页

作者： Alfredo Morales Hernández Mayra A. de león alfaro antonio Barrera Villatoro Ciro Falcony Teodoro Rivera Montalvo Juan Zarate Medina Instituto de Investigaciones en Metalurgia y Materiales Universidad Michoacana de San Nicolás de Hidalgo Morelia México Instituto Politécnico Nacional Centro de Investigación en Ciencia Aplicada y Tecnología Avanzada Ciudad de México México Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional Ciudad de México México

The aim of the present work was to investigate the luminescent properties of europium-doped lanthanum aluminate (laAlO3) powder prepared by Modified Pechini (MP) method. Samples were prepared at different Eu3+ concentrations and calcined at 1600°C. Structural and morphology characterizations were obtained by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscope (TEM). luminescent properties were analyzed by photoluminescence (Pl) and thermoluminescent phenomena. The XRD pattern shows pure lanthanum aluminate oxide laAlO3 with a rhombohedral structure. Photoluminescence studies of the powders was related to 4f → 4f(5D0 → 7Fi) (i = 1, 2, 3, 4) transitions of Eu3+ ion, the most intense emission of Eu3+ in laAlO3 was registered for the transition 5D0 → 7F1, for 5% of Eu3+. The recorded Tl glow curves of excited samples showed a main Tl peak, the main peak appeared its maximum as a function of excitation energy. The investigation demonstrates that polycrystalline laAlO3:Eu3+ powders calcined at 1600°C have interesting luminescent characteristics.
