    Localization and compartmentation of Al in the leaves and roots of tea plants

    Hajiboland R1,2, C Poschenrieder3

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 86-100, 2015, DOI:10.32604/phyton.2015.84.086

    Abstract Under acid soil conditions, solubility of aluminum (Al) increases leading to toxicity for plants. Al accumulator species such as tea, however, accumulate high levels of Al in tissues without toxicity symptoms. In this work, Al localization and compartmentation were studied in tea [Camellia sinensis (L.) O. Kuntze] grown hydroponically at 0 or 100 µM Al for eight weeks. Plant dry matter production was significantly higher in the presence of Al and accumulated up to 1.21 and 6.18 mg Al/g DW in the leaves and roots, respectively. About 40-50% of Al was partitioned into cell wall (CW)-bound fraction without any difference… More >

    Sodium sulfate exposure slows growth of native pecan seedlings

    Moreno-Izaguirre E1, D Ojeda-Barrios2, G Avila-Quezada2, V Guerrero-Prieto3, R Parra-Quezada3, T Ruiz-Anchondo2

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 80-85, 2015, DOI:10.32604/phyton.2015.84.080

    Abstract Pecan [Carya illinoensis (Wanngenh) K. Koch] is one of the most important nut crops in arid and semiarid regions of Mexico. Here, most pecans are grown in saline soils having poor permeability which are further degraded by the use of low-quality irrigation water. Salinity adversely affects both pecan nut quality and yield. Little work has been done to explore the physiological effects of salinity on native pecan trees. Here we examine physiological changes determined by exposure of pecan seedlings to sodium sulfate (Na2SO4) at four concentrations: 1000, 2000, 3000 and 4000 mg/L applied twice weekly over a 70 d period.… More >

    Effect of fruit maturity, seed weight and storage time on the viability and germination of the seed of candelilla (Euphorbia antisiphylitica Zucc.)

    Alvarado-Vázquez MA, R Foroughbakhch, MA Guzmán- Lucio, A Rocha-Estrada, JL Hernández-Piñero, ML Cárdenas-Ávila, BM Soto-García

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 70-79, 2015, DOI:10.32604/phyton.2015.84.070

    Abstract Candelilla (Euphorbia antisiphylitica Zucc.) is a very important plant resource in the arid lands of Northern Mexico. This is because the wax content coating the stem has unique properties which have been useful for multiple applications in the food industry, electronics, cosmetics, etc. However, the intensive exploitation of this resource has caused a great decrease in the populations of this species making necessary to consider strategies for their conservation and sustainable use. One of the primary needs with regeneration purposes is to know their reproductive processes, particularly the biotic and/or abiotic factors that determine the viability and germination of seeds.… More >

    Arthrobacter agilis UMCV2 accelerates growth of Pinus devoniana

    Valencia-Cantero E2, I Flores-Cortez2, J Ambriz-Parra1, P López-Albarrán1, C Velázquez-Becerra1

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 64-69, 2015, DOI:10.32604/phyton.2015.84.064

    Abstract Pinus devoniana is one of the most widely distributed species of Pinus in Mexico, and has a relevant economic and ecological importance. In this work, the effect of inoculating juvenile P. devoniana plants with the rhizobacteria Arthrobacter agilis UMCV2, and its dimethylhexadecylamine compound was studied under greenhouse conditions. Our results showed that A. agilis UMCV2 promoted growth of P. devoniana as a result of increases on height and stem diameter, fresh weight and chlorophyll concentrations. Under our experimental conditions, the bacterial dimethylhexadecylamine compound produced an increase in the concentration of chlorophyll. These data show the feasibility of using A. agilisMore >

    Seed dormancy release and germination characteristics of Corispermum lehmannianum Bunge, an endemic species in the Gurbantunggut desert of China

    Zhang LW1, HL Liu2*, DY Zhang2, WG Bian2

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 58-63, 2015, DOI:10.32604/phyton.2015.84.058

    Abstract Seed dormancy release and germination of Corispermum lehmannianum Bunge were tested using various treatments: temperature, cold stratification, gibberelins (GA3), dry storage and sand burial. Results showed that temperature and light did not affect the germination of fresh seeds, cold stratification and GA3 could improve seed germination, whereas dry storage and sand burial did not. The germination percentage was highest at 35/20 °C after the cold stratification and GA3 treatments. Corispermum lehmannianum seeds were classified as non-deep, Type-2, physiological dormancy (PD), whose seed dormancy could be released by cold stratification and GA3. More >

    Characterization and growth evaluation of Paspalum almum, Paspalum denticulatum and Paspalum vaginatum as lawns

    Saluzzo H1, PD Reinoso2,3, V Martínez2,3

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 51-57, 2015, DOI:10.32604/phyton.2015.84.051

    Abstract Morphological and growth characteristics of two Paspalum native species, and an enhanced species of the same genus, were evaluated for their potential use as lawns. Color; texture, stolon length and diameter, node number and length, width and number of leaves were determined under grass management conditions. The used plant material derived from the Paspalum collection (belonging to the PID UNER 2139 research project carried out at Facultad de Ciencias Agropecuarias). The trial consisted of twelve 1 m2 plots in four completely randomized blocks and was conducted from November 2010 to March 2011. All the characterictics were measured from the growth… More >

    Ocaña-de Jesús RL, AT Gutiérrez-Ibáñez, JR Sánchez-Pale, MD Mariezcurrena-Berasain, G Velázquez-Garduño, A Laguna Cerda, I Rojas Puebla

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 45-50, 2015, DOI:10.32604/phyton.2015.84.045

    Abstract The aim of the current research was to determine tomato (Solanum lycopersicum L.) microbiological quality produced under greenhouse conditions in 5 municipalities of the State of Mexico. Studies were conducted during the 2013 production cycle to know the risks and apply prevention strategies prior to its consumption. A microbiological analysis of samples of irrigation water, soil and 100 tomato fruits variety cid was performed to determine Aerobic Mesophiles, Total Coliforms and Fecal Coliforms.

    Huang FL1,2, GL Zhu2,3, YS Chen1,2, FJ Meng4, M Peng1,4, XF Chen1,2, ZB He3, ZY Zhang3, YJ Chen1,2

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 26-33, 2015, DOI:10.32604/phyton.2015.84.026

    Abstract Oil content and fatty acid composition were investigated on 12 castor varieties and strains by using the soxhlet extraction method and capillary gas chromatography. This was made to provide a reference and theoretical basis for castorbean breeding with high oil content, determine variability of seed compounds for breeding purposes, and broaden chemical material choices. Results revealed that crude fat percentage in seeds ranged from 18.91 to 35.84% with an average of 25.91%; the absolute content of ricinoleic acid varied between 171.65 g/kg and 314.03 g/kg with an average of 222.43 g/kg, and kernel crude fat percentage was between 24.28 and… More >

    Comparative analysis of fatty acids, tocopherols and phytosterols content in sunflower cultivars (Helianthus annuus) from a three-year multi-local study

    Ayerdi Gotor A1,5*, M Berger1, F Labalette2, S Centis3, J Daydé1, A Calmon1,4

    Phyton-International Journal of Experimental Botany, Vol.84, No.1, pp. 14-25, 2015, DOI:10.32604/phyton.2015.84.014

    Abstract Sunflower oil is naturally rich in both unsaturated fatty acids and numerous minor components, with high levels of α-tocopherol and phytosterols that could play an important role in plant protection. These micronutriments, tocopherols and phytosterols, also exhibit health benefits for humans including reducing both cardiovascular diseases and aging disorders. α−Tocopherol represents more than 95% of total sunflower tocopherol and has the greatest vitaminic activity. Furthermore, this oil contains high amounts of β-sitosterol which is a promising health beneficial phytosterol. The objective of this study was to compare the content and composition of fatty acids, tocopherols and phytosterols in sunflower oil… More >
