The landuse change detection in Taleghan catchment
The effects of global warming, climate change and landuse changes on catchment water balance and quality have become the main concerns in the watershed water resources management in recent years. One such area is the Taleghan watershed in the Northwest of Tehran, the Iran’s capital with an area of 930.62 km2. This watershed has undergone excessive landuse changes during the last two decades due to...

Determination of optimum seaweed concentration for mushroom cultivation and the ability of mushrooms to absorb iodine
The optimum concentration of seaweed (Laminaria schinzii) in grass as substrate for cultivation of the Oyster mushroom Pleurotus sajor caju was observed to be 10%. This concentration supported growth of highest numbers and biomass of mushrooms. Concentrations of seaweed above 10% suppressed mushroom growth. No growth occurred above 25%. The Oyster mushrooms absorbed iodine from the growth...

Effects of water shortage in late season on agronomic traits of rapeseed (Brassica napus L.)
Water deficit in the fall cultivation of Rapeseed occurs in cold and cool temperate regions, usually in the late period of growth, that is, the late spring and early summer. To examine the possibility of dealing with water deficit in the late season, appropriate experimental cultivars of the plant were cultivated in 2008 to 2009 and 2009 to 2010 cropping seasons at Karaj of Iran. An experiment...

Effect of salinity, salicylic acid, silicium and ascorbic acid on lipid peroxidation, antioxidant enzyme activity and fatty acid content of sunflower
In order to study effects of salinity, salicylic acid, silicium and ascorbic acid on lipid peroxidation, antioxidant enzyme activity and fatty acid content of sunflower, a pot culture experiment was conducted under controlled conditions. Sunflower seeds were sown into the pots and irrigated by Hoagland’s solution. Salinity was induced by adding sodium chloride (NaCl) into nutrient solution. In addition,...

Efficacy of two organic amendments and a nematicide for management of root-knot nematode (Meloidogyne incognita) of watermelon
A field experiment was conducted during two consecutive years for the management of root- knot nematode(Meloidogyne incognita) of watermelon with two organic soil amendments poultry refuse (3 and 5 t/ha), mustard oilcake (0.3 and 0.6 t/ha) and a nematicide Furadan 5G 40 kg/ha. Organic amendments were incorporated in the soil 3 weeks before and Furadan 5G on the day of seedling transplanting. PR 3 t/ha...

Chloroplast DNA genetic diversity between Asian cultivated rice (Oryza Sativa L.) and different types of cytoplasmic male sterile rice
The chloroplast DNA (cpDNA) genetic diversity in Oryza sativa and different types of cytoplasmic male sterility (CMS) lines was elucidated by comparing the polymorphic sites in nine highly variable regions. A total of 151 polymorphic bases were detected among 29 materials; of which 131 bases were identified...

In vitro induction of tetraploids from immature embryos through colchicine treatments in Clivia miniata Regel
The immature embryos of Clivia miniata Regel. cv. Ranchang were in vitro induced with 0.00, 0.01, 0.03 and 0.05% colchicine treatment for 10, 20 and 30 d, respectively on Murashige and Skoog (MS) medium supplemented with 2.0 mg L-1 a-Naphthaleneacetic acid (NAA) and 1.5 mg L-1 6-Benzylaminopurine (BA). A total of 14 tetraploids were obtained with an average induction...

Growth, blood metabolites and hormones in calves fed diets with different amounts of energy and protein during the pre- or post-weaning periods
We investigated the effects of diets differing in energy and protein concentrations given during pre- and post-weaning on hormone and metabolite levels in association to parameters of growth. Sixteen Aberdeen Angus calves four-day-old were allocated in individual pens during 105 days in a randomized complete design. Animals consumed ad libitum various diets differing in proportion of energy and...
