objective(s): epilepsy is a neurodevelopmental disorder which is strongly influenced by genetic and environmental factors. gestational stress has been shown to be an important factor for affecting seizure susceptibility. the present study was conducted to address whether gestational stress may affect pentylentetrazol (ptz)-induced epileptic behavior in rat offspring in a sex- and age- dependent...

kentucky bluegrass (poa pratensis l.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. the objective of this study was to investigate whether prohexadione-calcium (pro-ca) may play a role in promoting ...

Ongoing climatic changes have altered growing conditions for plants by limiting water availability and inducing unprecedented temperature increases, eliciting plant functional responses that compromise floral trait expression, reduce pollen production promote early self-pollination. In a controlled greenhouse study, of Collinsia heterophylla, an annual mixed-mated hermaphrodite, were grown unde...

In 1994, its second full production year, field-grown meristemmed 'Black Mitchum' peppermint performed differently than in 1993, when compared with a non-meristemmed treatment in a field trial at the OSU-COARC. The difference between years may be partly attributed to better meeting the fertility and soil moisture needs of meristemmed plants in 1994. Plants were not moisture-stressed near harves...

Shoot and root growth are differentially sensitive to water stress. Interest in the involvement of hormones in regulating these responses has focused on abscisic acid (ABA) because it accumulates in shoot and root tissues under water-limited conditions, and because it usually inhibits growth when applied to well-watered plants. However, the effects of ABA can differ in stressed and non-stressed...

In a field experiment the effects of irrigation with saline drainage water (seasonal average of 4.5 dS/m) and non-saline water (0.55 dS/m) applied by two different water management strategies (cyclic or blended saline water with non-saline water in different ratios) and two different irrigation methods (drip or furrow) were studied on growth and productivity of tomato (Lycopersicon esculentum M...
