Seed vigor is a complex property that determines the seed's potential for rapid uniform emergence and subsequent growth. However, the mechanism for change in seed vigor is poorly understood. The seeds of poplar (Populus × Canadensis Moench), which are short-lived, were stored at 30 °C and 75 ± 5% relative humidity for different periods of time (0-90 days) to obtain different vigor seeds (from 9...

While often used in everyday exchanges, feeling vigorous at work, that is individuals’ feelings that they have physical strength, emotional energy, and cognitive liveliness, has hardly been subjected to any conceptual inquiry or empirical research. In this chapter, I pursue the following objectives: (a) to review the range of behavioral science literature in which vigor has been considered as a...

Although studies on employee recovery accumulate at a stunning pace, the commonly used theory (Effort-Recovery model) that explains how recovery occurs has not been explicitly tested. We aimed to unravel the recovery process by examining whether off-job activities enhance next morning vigor to the extent that they enable employees to relax and detach from work. In addition, we investigated whet...

Nuclear-mitochondrial (NM) communication impacts many aspects of plant development including vigor, sterility, and viability. Dynamic changes in mitochondrial number, shape, size, and cellular location takes place during the cell cycle possibly impacting the process itself and leading to distribution of this organelle into daughter cells. The genes that underlie these changes are beginning to b...

When I was president of the U.S. National Academy of Sciences, I came to believe that the future success of humanity may depend on learning to use the tools of science—including the collection of objective evidence on what works and why—at all levels of decision-making. Thus, the National Academies have repeatedly addressed questions such as “How can we make a science out of education?” or “How...

Seed deterioration is when a seed loses its vigor and eventually viability. viability an important trait that directly influences seedling emergence crop yield. The rate of varies on several factors. Our main aims were to express the methods for testing deterioration, factors influencing aging, stages changes associated with Practical approaches overcome role reactive oxygen species during agin...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...
