Among abiotic stresses, drought is considered as the most important growth limiting factor, especially in arid and semiarid regions. Drought impacts can be adjusted by soil microorganisms. Accordingly, the present study was organized in order to the increase the tolerance of lemongrass (Cymbopogon citratus)to drought using plant growth promoting rhizobacteria (PGPR). Treatments were wa...

The potency of N-methylprotoporphyrin IX (N-methylPP) as a ferrochelatase (FC) inhibitor has been previously studied using crude chick embryo liver FC preparations. However, interactions between N-methylprotoporphyrin IX (N-methylPP) and impurities in the enzyme preparation may have compromised the results. The first objective of this study was to compare the potency of N-methylPP as an inhibit...

By using an electroactive species such as ferrocene (Fc), the electrochemical properties of bioorganic molecules were indirectly made accessible. 50-Fc-NH-ssDNAs have a redox potential of 430–440 mV (vs. AgjAgCl) in a borate buffer (pH 9), which is characteristic of ferrocene/ferrocenium (Fc/Fcþ) substituted by an amide group. The diffusion coefficient of Fc–ssDNA conjugates in a buffer solutio...

In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...

this experiment carried out to evaluate replacing effects of oyster shell (os) with filter cake (fc) of sugar beet industry on performance and quantity and quality of egg in  laying hens .in this trial the filter cake in two physical forms of powder and pellet in  five levels of 0, 25, 50, 75, and 100% replaced for oyster shell. each treatment had 3 replications. the experiment lasted 3 periods...

Since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, Plantago ovata Forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in Jiroft, Kerman Province, south of Iran. As the firstfactor, drought stress included four le...

shortage of water in arid and semiarid regions of the world can reduce growth and production of medicinal and aromatic plants, especially mentha species. in order to evaluate response of mint species to water deficit stress, an experiment was carried out using a completely factorial-randomized design with five replications at college of agriculturae, ferdowsi university of mashhad, iran. the fa...

Pot experiments were conducted during two successive seasons (2011/2012 and 2012/2013) at wire house of the National Research Centre, Giza, Egypt to study the effect of soaking canola seeds with glycinebetaine (GB) (10mM, 15mM and 20mM ) on growth, photosynthetic pigments, osomoprotectants, antioxidant enzymes, seed yield quality and quantity, in fever of antioxidant compounds and fatty acids c...
