in order to investigate the effect of organic and chemical fertilizers on growth characteristics of marjoram, a factorial experiment was conducted based on randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad during 2012-2013 growing season. treatments were comprised of four urea levels (0, 21.7, 108.7 and 195.7 kg.ha-1) a...
In order to recognize the soybean tolerant genotypes, a greenhouse as factorial experiment was conducted in form of randomized complete block design with three repetition in 2017 in Damavand. The first factor contained 15 soybean genotypes and second factor included two levels of normal irrigation and irrigation disruption in time of podding. The traits included plant height, reproductive ...
In this study, the effect of foliar spray of sodium nitroprusside (100 μM) as a nitric oxide donor on iron deficiency stress alleviation in cucumber plant was investigated. The results indicated that iron deficiency stress reduced growth parameters, total chlorophyll content, Fe content and antioxidant enzymes activity of catalase, ascorbate peroxidase as well as guaiacol peroxidase. Sodium nit...
Nitrogen deficit is one of the most limiting nutrients for plant production. Therefore, identifying diazotrophic indigenous inoculants to promote nitrogen fixation have a great importance in agriculture. In the current study, a number of rhizobacteria isolated from nodules of different legumes cultured in Kerman (IRAN) province. Isolates were screened for their ability to grow on N-free media. ...
Different dilutions, that is, 25, 50, 75, and 100%, of tannery effluent (TE) were chosen for the present study to assess the phytotoxic effects on Vigna mungo L. For amelioration purposes, different levels and combinations of iron and zinc were supplied to the plants along with 50% TE that is chosen on the basis of prior test under Petri dish culture. Cytotoxic and biochemical analysis and plan...
Greenhouse experiments in a completely randomized design were carried out to investigate the effects of nitroxin fertilizer (0, 1 and 2 li/ha) on morphological and physiological traits of Amaranthus retroflexus in 2013. The traits in the study included plant height, fresh and dry weight of shoots, roots, stem and leaf, Chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, anthocyanin, a...
Many experiments have been carried out to decrease the negative effect of drought stress and obtain suitable growth under water deficit conditions. Application of plant growth regulators (especially growth retardants) is one of the proposed methods. This study was conducted to investigate the effect of Cycocel application on growth of two olive cultivars (Shengeh and Roghani) under water stress...
in order to study the effect of different levels of the manure and foliar application of zn and mn fertilizers on the quantitative and qualitative yield of soybeans (var. williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two levels of mn...
The basic leucine zipper (bZIP) family of transcription factors plays an important role in the growth and developmental process as well as responds to various abiotic stresses, such as drought and high salinity. Our previous work identified GmFDL19, a bZIP transcription factor, as a flowering promoter in soybean, and the overexpression of GmFDL19 caused early flowering in transgenic soybean pla...
We investigated the role of GlyBet (100 mM) applied exogenously in alleviating water-deficit induced stress in indica rice cv. Pathumthani 1 (PT1). Exogenous GlyBet increased proline concentration in the leaf tissues of water deficit stressed plants depend on a degree of soil water content (SWC), especially at severe water deficit (25% SWC). Foliar GlyBet (100 mM) significantly enhanced chlorop...
