introduction: today, production of organic farming and gardening is rising. the use of organic fertilizers such as animal manure has a long history. in recent years, the use of fertilizers and manure for providing the nutritional needs of plants, improve soil physical and chemical structure and reduce the environmental issues have been observed. animal manures can increase soil organic matter a...

The fungal metabolite mevinolin, known to be a potent hypocholesterolemic agent, exerts in vitro a strong inhibitory effect on microsomal HMG-CoA reductase from etiolated radish seedlings at a concentration of about three magnitudes lower than the Km towards the natural substrate (S)-HMG-CoA (I50 = 2.5 x 10(-9)M). Beside this, mevinolin significantly inhibits the root elongation of radish as we...

In order to investigate the accumulation and bio-absorption of lead and cadmium in radish and cress, the present study has been conducted in a completely randomized design in three replicates in a hydroponic growing medium. The first factor includes the plant type at two levels (radish and cress), and the second factor is consisted of lead (Pb) (first experiment) at two levels (50 and 100 mg/L)...

An enrichment broth was developed for the efficient isolation of Escherichia coli O157 from radish sprouts. The broth was buffered peptone water containing 0.5% sodium thioglycolate (STG-BPW), which was designed to allow growth of E. coli O157 in starved and unstarved states. However, this medium suppressed the growth of non-carbohydrate-fermenting obligate aerobes whose colonial appearance on ...

In order to cultivate plants under low pressure in closed environment, the germination rate of seeds of white radish was investigated under low pressure, low oxygen partial pressure and condition of pure oxygen. The result of these experiments showed that the germination rate was affected by the oxygen partial pressure. From this fact, it is possible to lower the total pressure by using only th...

Inducible plant resistance against herbivores is becoming a paradigm of plant–herbivore ecology. Fundamental to understanding induced resistance and its evolutionary ecology is specificity of ‘‘induction’’ and ‘‘effects’’. Specificity in the induction of resistance refers to whether plant damage by various herbivores causes the same response in plants. Specificity in the effects of induced resi...

The present study sought to investigate the comprehension of Garden-Path structures by Iranian EFL learners. 50 female students of Kharazmi English Language Institute in Karaj participated in this study. All of the participants were native speakers of Persian studying in Kharazmi English language institute in Karaj, Iran. They ranged from 18 to 30 in terms of age. The participants were administ...
