introduction: oxidative stress seems to play a critical role in the degeneration of dopaminergic neurons in parkinson’s disease (pd). antioxidant compounds can deactivate and scavenge free radical. olive leaves are considered as a useful source of phenolic compounds. therefore, this study was designed to investigate the effects of methanolic olive leaf extract (ole) on neurobehavioral activity ...
breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...
plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. photoautotrophic and photomixotrophic systems could diminish these problems. the purpose of this study was to increase the chlorophyll...
چکیده: اسانس اندام هوایی دو گیاه onosma orientale و capparis spinosa بصورت جدا از هم (گل، برگ، ساقه) با استفاده از دستگاه کلونجر به روش تقطیر با آب استخراج نموده و ترکیبات موجود در اسانس ها شناسایی و مقدار آنها تعیین شده است. ترکیبات اصلی موجود در این دو گیاه شامل موارد زیر است. onosma orientale %stem %leaf %flower compound name n - 14.8 59.15 n-decane 1 23.28 24.51 7.91 alpha-eudesmol 2 ...
We agree with Knyazikhin et al. (1), who reported in a recent issue of PNAS that relationships between foliar nitrogen (%N) and near-infrared (NIR) canopy albedo appeared to be indirect and explained largely by differences in leaf and canopy structure, primarily between conifer and broadleaf species. We disagree, however, with the conclusion that %N–NIR correlations are necessarily spurious. On...
BACKGROUND In this study we carried out a genome-wide association analysis for plant and grain morphology and root architecture in a unique panel of temperate rice accessions adapted to European pedo-climatic conditions. This is the first study to assess the association of selected phenotypic traits to specific genomic regions in the narrow genetic pool of temperate japonica. A set of 391 rice ...
Isabgol is a major export oriented medicinal crop of India. The genetic variability available in this crop is limited owing to the narrow gene pool existing in our country. The physiological and growth characteristics of selected 7 species of Plantago were studied at DMAPR, Boriavi to investigate the relationship with the seed yield. Among the species studied, the lowest SLA (specific leaf area...
