Juvenile growth and bud set phenology were analyzed to study the biological basis of heterosis (hybrid vigor) in interspecific hybrids of Populus tremuloides Michx. (T) and P. tremula L. (Ta). Growth, measured as seedling volume index, was significantly higher for each of the two reciprocal interspecific crosses, T x Ta and Ta x T, than for the T x T intraspecific cross. Broad-sense heritabilit...

OBJECTIVE Analyzing the spatio-temporal relationship regarding the occurrence of cases of dengue in Colombia's Córdoba Department and the temperature, rainfall and the phenological state of vegetation (vigor and density). METHODS A statistical and cartographical study of spatio-temporal distribution regarding the occurrence of cases of dengue was studied in 30 selected municipalities. Simple ...

Abstract Application of plant growth regulators emerges as one the most reliable methods to enhance crop productivity and quality. However, knowledge is limited in seed quality hybrid rice subjected exogenous 6-Benzyladenine (6-BA) application during development. A 2-year experiment was conducted investigate effects 6-BA treatment after pollination on vigor its underlying regulatory mechanisms....

Characterization of the spatial variability vegetative vigor in vineyards can help improve performance site-specific management practices, or with different rates. using canopy proximal sensing has been a widely disseminated technique; however, southeastern Brazil, where utilization annual double pruning results winter harvest, knowledge role improving vineyard not yet applied. This study aimed...

Abstract: The use of computational resources to assess the physiological potential seeds has attracted attention researchers and professionals in seed sector. aim this study was evaluate vigor cowpea using Vigor-S software (Automated Seed Vigor Analysis System), comparison information provided by traditional tests that are recommended for species. Seven lots cultivar BRS Guariba were used. They...

PURPOSE The purpose of the present study was to evaluate the ergogenic effect of caffeine ingestion on mood state, simple reaction time, and muscle power during the Wingate test recorded in the morning on elite Judoists. METHODS TWELVE ELITE JUDOISTS (AGE: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ±6.57 m) participated in this study. Mood states, simple reaction time, and m...

OBJECTIVE Memory impairment is observed in adults with type 2 diabetes. The focus of this study was to determine whether acute carbohydrate consumption contributes to or exacerbates memory dysfunction. RESEARCH DESIGN AND METHODS The impact of consuming 50 g of rapidly absorbed carbohydrate (one half bagel and white grape juice) at breakfast was examined in 19 adults with type 2 diabetes. Sub...

A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...

The effect of different concentrations of hexavalent Cr on growth and biochemical parameters of two T. aestivum cultivars (Punjab-11 and Sehar-06) was investigated. No significant inhibition of seed germination was observed in both the cultivars at all the tested concentrations (P ˃ 0.05). A significant decrease in root length for both the cultivars was observed at all the Cr concentrations as ...

BACKGROUND Lecithin is a complex mixture of phospholipids which compose lipid bilayer cell membranes. Lipid replacement therapy, or administration of phospholipids for the purpose of repairing the dmaged cell membranes, had been shown to alleviate fatigue. The present study aimed to investigate the effect of soy lecithin on fatigue in middle-aged women, as well as other menopausal symptoms and ...
