Results indicated an overall difference within subjects for time (F [ 6, 45] = 12.257, p <.001. Univariate analysis revealed that the subscale scores of tension (F [1, 50] = 21.345, p <.01), vigor (F [1, 50] = 25.714, p <.01), and fatigue (F [1, 50] = 4.613, p <.05) significantly improved from the preoperative to postoperative time periods.
Root growth response to elevated CO2 differed between genotypes; elevated CO2 stimulated root growth in the non-vigorous cultivar Janz, but not in vigorous liner Vigor 18. High temperature reduces the positive effect that elevated CO2 has on root growth and proliferation.
The breeding line Vigor 18 selected for vigorous shoot and root growth and the commercial cultivar Janz were grown in rhizo-boxes inside specially designed tunnel houses under ambient (390 400 μL L−1) and elevated CO2 (700 μL L−1), and ambient and 3 °C above the ambient temperature.
Will jobs continue to expand through the spring, and with enough vigor — 300,000 a month, say — to substantially reduce the unemployment rate?
The proper synchronization of the internal clock and external light/dark cycles results in better plant fitness, survival, competitive advantage [3] and growth vigor [4].
Positive genetic and epigenetic interactions between genomes in hybrids, particularly allopolyploids, are thought to lead to hybrid vigor [35], which also seems to apply well to the present Oryza study case.
Many prominent hypotheses concerning the role of dopamine in reward pursuit, such as the views related to allocation of effort and response vigor [25], [26], [72], [73], were developed to account for the effects of dopaminergic agents on performance maintained by natural rewards, such as food and water.
Furthermore, reward motivation can energize behavior [13], leading to decreased response times [14] and increased response vigor [15, 16].
This finding fits well with recent observations of enhanced energization of action through reward as expressed in faster reaction times [14] and increased response vigor [13, 15, 16].
Zinsser lived to see American medicine develop from a "relatively primitive dependence upon European thought to its present magnificent vigor" (4).
Cyst formation is typically counted after 4 weeks but because the root tissues used often exhibit significantly reduced vigor 3-4 weeks into such assays, and to expedite and possibly improve resistance scoring, we investigated the scoring of resistance phenotypes at an earlier time point.
