Plant growth regulators, especially those applied directly to the root system, are thought to significantly reduce growth of the root systems. Various perennials were treated with uniconazole (Concise, Fine Americas, Inc.) to evaluate effects on plant height as well as shoot and root dry weights. Plant height of Lobelia cardinalis was not affected by a 1 ppm uniconazole liner dip, but shoot dry...

The kinetics for the reduction of sulfate alone and for concurrent uranium [U(VI)] and sulfate reduction, by mixed and pure cultures of sulfate-reducing bacteria (SRB) at 21 +/- 3 degrees C were studied. The mixed culture contained the SRB Desulfovibrio vulgaris along with a Clostridium sp. determined via 16S ribosomal DNA analysis. The pure culture was Desulfovibrio desulfuricans (ATCC 7757). ...

1. Although in blood cells decreased magnesium concentrations and increased sodium concentrations in essential hypertension have often been described, only sparse data exist on cellular magnesium or sodium content and exchange in vascular smooth muscle cells.2. Therefore in aortic smooth muscle cells from 10 spontaneously hypertensive rats (SHR) of the Münster strain and 10 normotensive Wistar-...

Abstract—Reducing the weight of transformers while providing good performance, cost reduction and increased efficiency is important. Weight is one of the most significant factors in all electrical machines, and as such, many transformer design parameters are related to weight calculations. This study presents a comparison of the weight of oil type transformers and dry type transformer weight. O...

Live coral is harvested throughout the Indo-West Pacific to make lime, used in the consumption of the world's fourth-most consumed drug, betel nut. Coral harvesting is an environmental concern; however, because lime-making is one of the few sources of income in some areas of Papua New Guinea (PNG), the practice is unlikely to stop. To better manage coral harvest, we used standard fishery-yield ...

This study determined the effect of light intensity and photoperiod on the dry cell weight and total amount of carotenoids in four isolates of purple non-sulfur bacteria obtained from shaded and exposed microhabitats of a mangrove ecosystem in Kota Kinabalu, Sabah, Malaysia. The initial isolation of the bacteria was carried out using synthetic 112 medium under anaerobic conditions (2.5 klx) at ...

dwarf chicory (cichorium pumilum jacq.) is one of the annual species from chicory genus grows in western and southern parts of iran. to date no study on this species has been carried out under the field conditions. in order to determine the suitable planting date of dwarf chicory, an experiment was conducted in a split plot layout based on randomized complete block design with three replication...

Background: In rainfed agriculture, lentil is considered an important legume crop. But in conditions adequate soil moisture condition a major obstacle that leads to reduced germination per cent, slow down growth of the seedlings and finally reduction yield. Seed priming alternative which can improve percentage seedling establishment lentil. Methods: The present work, deals with (Lens culinaris ...

Garden orache (Atriplex hortensis L.), a halophytic forb in the family Chenopodiaceae, is well adapted to dry saline habitats. Here, we presented the results of the effect of salinity and seed weight on seed germination and radicle emergence of A. hortensis. Highest germination percentages were obtained under non-saline conditions and increases in salinity inhibited seed germination with less t...

in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...
