Lower plant transpiration rate (TR) under high vapor pressure deficit (VPD) conditions and early plant vigor are proposed as major traits influencing the rate of crop water use and possibly the fitness of chickpea lines to specific terminal drought conditions-this being the major constraint limiting chickpea productivity. The physiological mechanisms underlying difference in TR under high VPD a...

This thesis is devoted to a better understanding of the vigor with which primates perform everyday actions. Indeed, there are great differences in baseline amounts of movement vigor across individuals. However, vigor depends upon the environment, and the reward landscape. The first portion of this text focuses on the effects that the reward landscape has on movement vigor. Chapter 2 demonstrate...

Since the germination test is still the main method for evaluating seed vigor of sweet corn, it is necessary to study the rapid methods for evaluating their vigor. First, two vigor levels of 9 super sweet corn and 9 sugar enhanced corn hybrids were distinguished by accelerated ageing treatment. Next, their vigor statuses were tested by rapid methods such as electrical conductivity (EC), soluble...

This paper aims to present a review of seed technology, seed germination and vigor methods using image processing. Computer–aided image analysis techniques have been recently developed in monitoring seed growth and vigor. Their integration with the standard germination test is needed to describe the germination performance of a seed sample with high accuracy. The use of various modern image acq...

Yield, growth, and vigor of individual grape vines were correlated with nematode population densities in a series of California vineyards. In a Hanford sandy loam soil, Xiphinema americanum densities showed negative correlations with yield, growth, and vigor of vines. When vines were categorized according to vigor, X. americanurn densities had little relationship to yield of high-vigor vines, b...

Escalating stratums of breeze vigor, which is variable, difficult to predict accurately, and escalating connected via power electronic converters, are changing how electricity grids are planned, designed, and operated. . Systems with high breeze penetration are also experiencing dramatic changes to the operating regimes of conventional resources to areas with large loads. Optimal diminutive-ten...

The last 30 years have led to increasing dissatisfaction by seed producers and consumers with the standard germination test as the sole criterion of seed performance potential presented on a seed label. As a result, new seed testing techniques have been formulated known as seed vigor tests that provide more sensitive measures of seed quality. The ISTA and AOSA Vigor Test Committees have been at...

Progressive depletion of midbrain dopamine neurons (PDD) is associated with deficits in the initiation, speed, and fluidity of voluntary movement. Models of basal ganglia function focus on initiation deficits; however, it is unclear how they account for deficits in the speed or amplitude of movement (vigor). Using an effort-based operant conditioning task for head-fixed mice, we discovered dist...

Although seed vigor is a complex physiological trait controlled by quantitative trait loci, technological advances in the laboratory are being translated into applications for enhancing seed vigor in crop plants. In this article, we summarize and discuss pioneering work in the genetic modification of seed vigor, especially through the over-expression of protein L-isoaspartyl methyltransferase (...

We examined the effects of burnout and vigor on the incidence of hyperlipidemia. Based on the bivariate theoretical approach to negative and positive affects and on past studies on the prediction of blood lipids by burnout and vigor, we expected increases from Time 1 (T1) to Time 2 (T2) in burnout levels to be associated with an increase in the risk for hyperlipidemia and T1-T2 increases in vig...
