to evaluate the effects of organic, chemical and integrated fertilizers on yield and yield components of turnip (brassica rapa) an experiment was conducted in research farm of college of agriculture, university of tehran, iran, during 2009 - 2010 growing season. the treatments were arranged as randomized complete blocks design with three replications and fifteen different fertilization systems....

We administered foliar applications of 50, 100, and 200 mg L-1 selenium (Se, selenite) on turnip (Brassica rapa var. rapa Linn.) and detected the changes in the main nutrient components in fleshy roots. Results showed that the foliar application of Se (IV) significantly increased the Se content in turnip, and Se (IV) positively affected the uptake of several mineral elements, including magnesiu...

The detrimental effects of drought have adverse impacts on the crop yield as global climatic changes put unusual pressure water resources. challenge attaining security is key for sustainable development crops. Zinc (Zn2+) an important nutrient that helps to alleviate stress by modulating growth and Recently, zinc nanoparticles (ZnNPs) been used a novel strategy fertilization This study was spec...

Heterodera schachtii developed to maturity and reproduced on the lateral roots of defoliated sugarbeet which were buried to a depth of 2.5 cm in sterilized soil and inoculated with cysts. Nematodes did not develop on detached lateral roots or on roots of young defoliated beets which did not have a large tap root. The storage roots of large rooted plants were sliced, placed in small jars, inocul...

This study was carried out to determine the consequence of foliar application agmatine (0 and 0.5 mM), on growth, physiological biochemical traits, yield turnip (Brassica rapa L.) plants grown under water stress or salt conditions. The effect three irrigation regimes (100%, 80% 40% field capacity) concentrations (0, 100 200 mM NaCl) in pots greenhouse conditions were studied. Water deficit deve...

abstractbackground : the presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations.   materials and methods: a total of 56 samples from 18 different foodstuff ...

The Drosophila mutant turnip was initially isolated based on poor learning performance (Quinn, W.G., Sziber, P.P., and Booker, R. (1979) Nature 277, 212-214). Here we show that turnip is dramatically reduced in protein kinase C (PKC) activity. In addition, turnip flies are deficient in phosphorylation of a 76-kDa head membrane protein (hereafter pp76) which is a major substrate for protein kina...

Introduction: Many plants with anti-oxidant properties proved to be effective on diabetes treatment. Brassica napus (turnip) is an anti-oxidant plant consumed raw or cooked. In this study, we examined and compared hypoglycemic and hypolipidemic properties of raw and cooked Brassica napus in diabetic rats. Objectives: Due to measuring bioactive component of Brassica napus as a rich source of fla...

Exposure of root tissue from a susceptible variety of sweet potato to low concentrations of ethylene induced a resistance to infection by Ceratocystis fimbriata and an increase in the activity of peroxidase and polyphenoloxidase in the tissue. Susceptible tissue that was inoculated with a pathogenic strain of C. fimbriata or a nonpathogenic strain that can induce resistance liberated more ethyl...

The presence of plant-uncoupling mitochondrial protein (PUMP), previously described by Vercesi et al. (1995), was screened in mitochondria of various organs or tissues of several plant species. This was done functionally, by monitoring purine nucleotide-sensitive linoleic acid-induced uncoupling, or by Western blots. The following findings were established: (1) PUMP was found in most of the hig...
