Thirty rice cultivars were evaluated for salinity tolerance during the seedling stage and were divided into five tolerance groups including tolerant (T), moderately tolerant (MT), moderately susceptible (MS), susceptible (S) and highly susceptible (HS) which comprised 5, 10, 9, 4 and 2 cultivars respectively. Genetic diversity of all rice cultivars was evaluated using random amplified polymorph...

BACKGROUND Androgen levels in the prostate may influence carcinogenesis in this organ. Inhibitors of the enzyme 5alpha-reductase block conversion of testosterone to the more active androgen dihydrotestosterone. The use of a 5alpha-reductase inhibitor, finasteride, in the chemoprevention of prostate cancer is being evaluated in a clinical trial. PURPOSE This study was conducted to determine if...

BACKGROUND AND PURPOSE We recently demonstrated that endogenous nitric oxide (NO) modulates collateral blood flow in a neonatal stroke model in rats. The inhalation of NO (iNO) has been found to be neuroprotective after ischemic brain damage in adults. Our objective was to examine whether iNO could modify cerebral blood flow during ischemia-reperfusion and reduce lesions in the developing brain...

tulip is one of the most important flowers to precocity. treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. this study carried out about three tulip cultivars includes ‘lacourtine’, ‘yokohama’ and ‘red favourite’. the results showed that gibberellic acid reduced significantly stem l...

BACKGROUND Development of insecticide resistance occurred due to the continuous and misuse of synthetic insecticides therefore, the recent study was conducted to explore eco-friendly plant extracts that have some potential to suppress mosquito larval population. METHODS WHO recommended mosquito larval bioassay method for insecticide was used while for the analysis of citrus oils for limonin a...

Morphological studies of the rat lung exposed to 20 ppm NO2 for 20 hr (experiment 1), to 0.5 ppm for 19 months (experiment 2), and to 10 ppm for 14 days (experiment 3) were conducted. Changes in the mast cells of the tracheas and main bronchi of rats exposed to 0.5 ppm (experiment 4) were also observed. In the alveolus, cytoplasmic blebbing occurred in a small number of type I cells immediately...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (...
