Stomata of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) leaves failed to open in the light and close in the dark or respond to changes in the CO(2) concentration of the atmosphere in either light or dark when the leaves were in an O(2)-free atmosphere. In contrast, the expected responses to environmental changes were found in atmospheres containing 1.5% O(2). It appears that O(2...

A polar gibberellin active in the dwarf rice (Oryza sativa L.) seedling and barley (Hordeum vulgare L.) half-seed assays was extracted from immature sour cherry (Prunus cerasus L.) seed and identified as gibberellin A(32) by gas-liquid chromatography and selected ion monitoring.

Current study was set up to determine the response of 12 Iranian winter diploid barley (Hordeum vulgare L.) cultivars to anther culture on solid FHG induction medium supplemented with 90 mg/l sucrose, 2 mg/l 2,4-D and 0.1 mg/l kinetin. For cold pretreatment each selected spike was kept in a refrigerator at 4 C for 14 days. The experimental design consisted of a completely randomized design (CRD...

To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...

In this paper, we studied polyetheneglycol (PEG) pretreatment effect on the mature embryo culture in vitro by using barley (Hordeum vulgare L.) seeds. Meanwhile, we analyzed and assayed its mineral element and endogenous hormone level. The experimental results were as follows: (1) PEG-6000 imbibition could obviously slow down the water timecourse absorbed by barley seeds; (2) 10% PEG-6000 treat...

The primary genepool of barley comprises two subspecies - wild barley (Hordeum vulgare subsp. spontaneum) and cultivated barley H. vulgare. subsp. vulgare. The former originated 5.5 million years ago in southwest Asia and is the immediate ancestor of cultivated barley, which arose around 10,000 years ago. In this study, the specific resistance of a set of 146 wild barley accessions, maintained ...

Barley (Hordeum vulgare L.) is a well-known cereal plant. Young barley leaf is consumed as a popular green-colored drink, which is named "Aojiru" in Japan. We examined the effects of barley leaf powder (BLP) and insoluble fibers derived from BLP on postprandial blood glucose in rats and healthy Japanese volunteers. BLP and insoluble fibers derived from BLP suppressed the increment of postprandi...

Barley (Hordeum vulgare) is an important cereal grain that is used in a range of products for animal and human consumption. Crop yield and seed quality has been optimized during decades by plant breeding programs supported by biotechnology and molecular biology techniques. The recently completed whole-genome sequencing of barley revealed approximately 26,100 open reading frames, which provides ...

Fructan was precipitated from a water and ethanol extract of oat (Avena sativa L.) and barley (Hordeum vulgare L.). The degree of polymerization and response on a differential refractometer, based on peak area and height, was compared to fructan collected from a lead-based HPLC column and to commercially available inulin. Statistically significant differences are discussed.
