As changes in air temperature, precipitation, and air humidity are expected in the coming decades, studies on the impact of these environmental shifts on plant growth and functioning are of major importance. Greatly understudied aspects of climate change include consequences of increasing air humidity on forest ecosystems, predicted for high latitudes. The main objective of this study was to fi...

A new species from Iran is described and illustrated here as Kickxia iranica (Plantaginaceae). Kickxia iranica is morphologically similar to K. commutata, a species native to Mediterranean region, however it can be distinguished from the latter by leaf shape, color of corolla, habit, stem branching and length of leaf, petiole, pedicel and corolla. Notes on its distribution, ecology and phenolog...

The antimicrobial activity of aqueous extract leaf and stem of Santalum album was performed against Escherichia coli, Staphylococcus aureus and Pseudomonas. S. album leaf extract showed inhibition to E.coli (0.8mm), Staphylococcus aureus (1.0mm) and Pseudomonas (1.4mm) were as stem extract showed inhibition on E.coli (0.6mm), Staphylococcus aureus (0.4mm) and seudomonas (1.0mm) respectively. Ho...

This study was carried out to evaluate the effect of soil application of humic acid on growth and physiological indices of pistachio seedlings ("Badami Zarand" rootstock) under drought stress. This experiment was arranged as a completely randomized design with three replications in greenhouse conditions. The experimental treatments consisted of humic acid (0, 30 and 60 gr in 4 kg-1 s...

BALASUBRAMANIAN, G., UDAYASOORIAN, C. & PRABU, P. C. 2007. Effects of short-term exposure of simulated acid rain on the growth of Acacia nilotica. The response and measurable effects of simulated acid rain at different pH levels of 3.5, 4.5, 5.5, 6.5 and 7.0 on Acacia nilotica seedlings grown on black and red soils were investigated for six months. A set of 10 potted seedlings in each treatment...

in order to study of efficiency total dual purpose herbicide and mixed granestar and acsiyal herbicides, and response of wheat at growth various stages to the aforementioned herbicides, an experiment with randomized complete block design with three replications were conducted during 2008-2009 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments in...

AIM This study was designed to determine the proximate composition and mineral content of Costus afer leaf and stem, as well as to identify the most active antioxidant fraction. MATERIALS AND METHODS The proximate composition and mineral analysis of C. afer leaf and stem were performed using the standard methods described by Pearson and Association of Official Analytical Chemist while the 1,1...

Ginseng has been used as a general tonic agent to invigorate the human body as an adaptogenic agent. In a previous report, we have shown that ginseng contains a novel glycolipoprotein called gintonin. The main function of gintonin is to transiently enhance intracellular free Ca(2+) [Ca(2+)]i levels in animal cells. The previous method for gintonin isolation included multiple steps using organic...

in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

Morphological characters such as main stem length (cm), number of branches per plant, leaf length (cm), number of leaves per main stem, number of leaflets per leaf, diameter of main stem (mm), pods / main stem and seeds / pod as well as agricultural herbage yield (t ha), dry matter yield (t ha), seed yield (t ha), crude protein (%) were investigated in Trakya, during the 1999-2002. The maximum ...
