abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

a pot experiment was designed to evaluate the effect of trichoderma spp. on yield and yield components of wheat (cv. n81) under different levels of cadmium nitrate. experiment was arranged in factorial based on completely randomized design with three replicates. trichoderma harzianum at two levels (with and without inoculation) and four levels of cadmium nitrate (0, 50, 100, 150 mg l-1) were th...

In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers. We present distribution and fault tolerance strategies of a meta-index that combines partial trace of object movements with aggregated data about the number of objects in the database servers. The degrees of distributi...

Insulin resistance, insulin secretion, and glucose tolerance may predict weight change. A total of 1,194 adults aged 39-69 years at baseline (46% with normal glucose tolerance according to World Health Organization criteria, 23% with impaired glucose tolerance, and 31% with type 2 diabetes mellitus who were not taking insulin) were evaluated at baseline (1992-1994) and after 5 years. Baseline i...

This study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. To screening quantitative indices of drought tolerance, genotypes of safflower (Carthamus tinctorius L.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). Significant positive correlatio...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...

Development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. Selection of such plant species are required to combat air pollution based on their tolerance level. Present study was undertaken to evaluate the tolerance level of higher plants in East of Esfahan city, Iran, during 2011 in terms of assessing Air Pollution Tolerance...

Since Baker’s [Baker, F.S., 1949. A revised tolerance table. J. For. 47, 179–181] classic contribution, shade tolerance indices have not been much modified for North American plant species. While many common tree and shrub species are included in the shade tolerance index, much less is known about this characteristic for the abundant and rich understory vascular and nonvascular plant layers. Th...
