this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

effect of different co2 concentrations on sucrose metabolizing enzymes and on carbohydrate metabolism was studied for eight blackgram (vigna mungo l. hepper) genotypes grown in open top chambers under ambient (380 µmol mol-1) vs. elevated co2 (550 and 700 µmol mol-1) levels. the higher acid invertase activity over neutral invertase indicated the major role of acid invertase in sucrose breakdown...

We are living in a great Greenhouse: our planet, the Earth. This sustainable system is almost closed, except the radiative energy received from the Sun. Understanding and respecting its principles is the only guaranty for a safe future of our species. The Greenhouse effect is a process by which a part of the incident solar energy is trapped by the lower atmosphere due to the action of some atmo...

Of the plants commonly found in Los Angeles County whose responses to smog 2 have been under extensive observation, Poa annua (annual bluegrass) was selected as one worthy of intensive study. It was early reported as one of the most sensitive of the plants observed in the field (11). Because it has a regular habit of growth, can be easily and quiekly grown in small containers, and because the b...

Few-layer graphene is grown on copper and nickel substrates at high rates using a novel flame synthesis method in open-atmosphere environments. Transmittance and resistance properties of the transferred films are similar to those grown by other methods, but the concentration of oxygen, as assessed by X-ray photoelectron spectroscopy, is actually less than that for graphene grown by chemical vap...

The expression of the transcriptional regulatory protein LasR, a main component of the quorum-sensing (QS) system in Pseudomonas aeruginosa, was recently found to be sensitive to several environmental factors in addition to its dependency on cell density. However, the inherent effects of the different factors have seldom been separately demonstrated due to concurrent changes of culture conditio...

UNLABELLED The naturally occurring compound, fumaric acid, was evaluated as a potential preservative for the long-term storage of cucumbers. Fumaric acid inhibited growth of lactic acid bacteria (LAB) in an acidified cucumber juice medium model system resembling conditions that could allow preservation of cucumbers in the presence of sodium benzoate. Forty millimolars of fumaric acid were requi...
