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 >

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 >

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. The methodology used were those according to the Official Mexican Standards NOM- 109-SSA1-1994, NOM-110-SSA1-1994, NOM-092-SSA1-1994, NOM-113-SSA1-1994, and the Regulations of the National French Organization for Standardization (AFNOR)… More >

Abstract Sargodha district is one of the least studied regions of Pakistan regarding its ethnobotanical values. This paper is the first report related to the documentation and conservation status of the tree species in the Sargodha district, and their folk ethnobotanical uses. An interview base survey was conducted in the study area in 2010-2013. The ethnobotanical data revealed the use of 100 tree species (6 gymnosperms, 94 angiosperms) belonging to 77 genera (6 gymnosperms, 71 angiosperms) and 39 families (4 gymnosperms, 35 angiosperms), with the Fabaceae ranking first with 19 tree species, followed by the Moraceae (12 species). Tree species like… More >

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 >

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 >

Abstract An experiment with increasing rates of fertilizer and manure in silage corn was established to evaluate the agronomic crop response and to estimate the manure nitrogen availability. The treatments were designed to deliver 0, 67, 100 and 133% of the crop nitrogen requirements (CNR), using ammonium sulphate and manure as N source. Dry matter (DM) yield was similar among treatments receiving N, but those values were greater than those found in the control. Nitrogen extraction at harvest was not statistically different in treatments with fertilizer or manure, but it was higher in these treatments than in the control without N… More >

Abstract Maize (Zea mays L.) tortilla is the major staple food for the Mexican population. Nine tropical maize genotypes were evaluated. All samples had white grains, a common characteristic in tropical maize, and therefore they were appropriate for nixtamalized flour industry. Grain, flour, masa and tortilla characteristics of each maize genotype were evaluated. Length, width, thickness, weight of 1000 grains and hardness of grain were determined. Moisture content, proteins, fat, ash, mean particle size, water absorption index, enthalpy, and flour temperature were also evaluated. Adhesiveness and cohesiveness were evaluated in masa. Moisture content, protein, capacity to puff up, roll making, tension… More >

Abstract The construction of a ski slope implies a strong environmental impact as a result of the removal of the vegetation cover. The need to protect the soil requires a rapid restoration of vegetation, which is often done with commercial seed mixtures that can cause a negative impact on these high mountain ecosystems. Thus, the use of seeds of native species is essential, especially in areas rich in endemic species. The compaction of snow as a result of the preparation of the ski slopes causes the soil to freeze. This hinders the germination of seeds, especially those of shrub species. This… More >

Abstract The effect of fire on growth and nutritive value of Saccharum griffithii Munro ex Boiss-ravennae (Linn.) Murr. hybrid, a low palatable perennial grass in the semi-arid region of the highlands of Balochistan, Pakistan, was evaluated during 2008 and 2009. Prescribed fire treatments were applied in February 2008 and 2009 at the dormant stage of vegetation. Different growth parameters (tiller height, tiller number/plant), forage production (fresh, dry) and nutritive value (crude protein, ash) were compared with control (unburnt) plots. Fire increased the number of tillers, and the fresh and dry forage production in both years. Fire also improved the crude protein… More >
