Seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. Many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. Seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. Du...
PURPOSE/OBJECTIVES To test a multicomponent intervention to prevent and treat osteoporosis in breast cancer survivors. DESIGN Descriptive, correlational. SETTING Midwestern urban and rural sites. SAMPLE 27 postmenopausal breast cancer survivors between the ages of 42-65 who had completed treatment, except for tamoxifen, and were not candidates for hormone replacement therapy. METHODS Bo...
Loss of aquatic plant species has occurred in coastal and freshwater habitats throughout the world. In particular, population and habit loss of the submerged aquatic species, Vallisneria americana Michx., have made it a potential restoration candidate. For successful restoration, reliable seed sources are vital for producing plants or for direct seeding. Seed survival and their ability to retai...
The main purpose of this research was to evaluate how duration and priming method may affect the germination and growth of cumin seed (Cuminum cyminum L.). The study was carried out in 3 replication by using a randomized completely block (RCB) design. The experimental treatments included: control, [hydro-priming in two durations of 24 and 48 h], [osmo-priming (0.2% of KNO3 in 24 and 48 h, 0.3% ...
background employee engagement is the emotional commitment of the employee towards the organisation. we aimed to analyse baseline work engagement using utrecht work engagement scale (uwes) at a teaching hospital. methods we have conducted a cross-sectional study within the national health service (nhs) teaching hospital in the uk. all participants were working age population from both genders...
The analysis and forecasting of extreme climatic events has become increasingly relevant to planning effective financial and food-related interventions in third-world countries. Natural disasters and climate change, both large and small scale, have a great impact on non-industrialized populations who rely exclusively on activities such as crop production, fishing, and similar livelihood activit...
F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics o...
Badea is known for the size and shape of fruit, or as giant passion fruit. The propagation passifloraceas mainly done by means seeds. Seed conservation one main steps in seedling production that makes it possible to guarantee maximum quality theseed a given period oftime can be through refrigeration.The experiment was conducted greenhouse Federal Institute Education, Science Technology Tocantin...
Seed quality includes three aspects, namely genetic quality, physical and physiological quality. Physiological is an aspect of seed as indicated by viability vigor. This study aims to analyze the effect different types sound exposure on early growth corn seeds, long maize seeds. The research was carried out in laboratory Faculty Agriculture, Teuku Umar University. September 20 - October 19, 201...
