this experiment was conducted, to study the effect of planting time and planting density on savory (satureja sahendica bornm.) in 2012 in alborz research station, research institute of forests and rangelands, karaj, iran. the experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. the main plots were planting times in two levels ...

Flowering patterns are defined by the timing, duration, and frequency of flowering. Plants, particularly in the tropics, vary enormously with respect to these main variables of flowering. We used data from 302 tree species in a wet tropical forest to test a series of predictions regarding timing, duration, and frequency of flowering and examined the effect of each variable on the other two. Bec...

The number of 88 rats was chosen, after 21 days, they were ablactated and categorized them as following groups:
 control group 1 has a cage 8 in social condition. After 6 weeks saline injection (1mg / kg), the yawning behavior is recorded for 60 minutes. Group 2 conditions receiving ethanol months, each serving 600 mg kg. 3 isolation without treatment with agonist antagonist, Opioid alcoho...

Clinical observations suggest the involvement of nicotinic acetylcholine receptors (nAChRs) in depressive illness. There is no clear cut evidence that nicotine produces an antidepressant effect. The antidepressant effect was assessed by the forced swimming test using male albino mice. Nicotine (1.2 mg/kg s.c.) given 15 min. before the test exerted no effect on immobility. Given 30 min before th...

The use of chemical fertilizers, which in the long term constitutes a source environmental degradation, has led farmers to organic sources as alternative soil amendments. However, fertilizers alone may not restore fertility highly degraded soils, hence need for integration and mineral fertilizers. objective study was improve tomato productivity. carried out using Fisher block design, with three...

The pharmacokinetics of levamisole was studied in 20 broiler breeder chickens (chickens that give eggs to breed broilers). A single dose of levamisole (40 mg/kg) was administered orally or intravenously to chickens before the onset of egg production, prelay (age = 22 weeks), and repeated at the peak of egg production (age = 32 weeks). A high-pressure liquid chromatographic with ultraviolet dete...

Satureja hortensis L., (summer savory) is an annual, herbaceous aromatic and well-known medicinal plant. S. hortensis essential oil has a high percentage of carvacrol which is responsible mainly for its biological activity. The biomass production, essential oil composition and mineral content of Satureja hortensis are known to be dependent on its growth and development conditions. The aim of th...

Peony plants require temperate winter temperatures to break underground bud dormancy and allow shoot emergence flowering in spring. This study assessed whether artificial chilling at 4 °C for 2–6 weeks could induce under subtropical conditions. It also pre-treatment cool prior chilling, or gibberellin application after promoted flowering. Artificial 6 the greatest emergence. Pre-treatment did n...
