Teak is a wood-producing plant that in great demand by the community. However, teak seeds are challenging to germinate due dormancy, so special treatment needed before planting. This research aimed determine effect of hydrochloric acid and soaking time on breaking dormancy seed improve its viability. The first factor was concentration with four levels, i.e., 0 M, 0.5 1 1.5 M. second submerging ...

Seed storability of 22 selected soybean mutant lines from Argomulyo population irradiated by gamma ray were assessed rapid aging tool, APC-IPB 77-1MM. viability and vigor parameter observed due to genetic factors. The 90% ethanol was applied for 20, 40, 60 80 min as accelerated test. M100-96-53-6 estimated that has good with less seed deterioration rate expressed slow slope germination percenta...

effect of free and symbiotic nitrogen fixing bacteria on seed and seedling produced seeds under deficit irrigation was conducted in laboratory and field experiments in 2006. in laboratory of karaj’s seed and plant research and certificate institute an experiment was conducted based on factorial in form of completely randomized design with four replications and in field’s of islamic azad univers...

An investigation was initiated to examine the effects of carbon soot collected from exhaust tube of 15 years old petrol and diesel operated vehicles on gram seed germination and biochemical changes of seedling. In view of the widespread cultivation of gram seed in India and long-term impact of black carbon is the warming of the atmosphere as per the recommendation of IPCC (2007). Black soot wer...

This study of 62 dyads of employees (N = 124) examined the crossover of work engagement-a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption. We hypothesized that work engagement crosses over from an employee (the actor) to his or her colleague (the partner) on a daily basis. The frequency of daily communication was expected to moderate t...

This study examined the effect of cosmetic therapy on frontal lobe activation as revealed by topographic near-infrared spectroscopy (NIRS). We evaluated emotional responses to a photograph of a face with/without makeup by 22 healthy female volunteers (mean age, 52 ± 10.5 years). The results of the first-round analysis showed a significant increase of oxy-Hb in the frontal lobe area when the sub...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

A variety of mechanisms have been proposed to account for the extension of life span in seeds (seed longevity). In this work, we used Arabidopsis (Arabidopsis thaliana) seeds as a model and carried out differential proteomics to investigate this trait, which is of both ecological and agricultural importance. In our system based on a controlled deterioration treatment (CDT), we compared seed sam...

Our goal in this essay is to review the hypothesis that females choose mates by the evaluation of male motor performance. We define motor performance as vigor, the ability to perform energetically expensive acts repeatedly, or as skill, the ability to perform difficult motor tasks well. Motor performance reflects most aspects of whole-organism performance that relate to survival, and thus shoul...
