Plant growth promoting rhizobacteria (PGPR) have been proposed as a useful tool for enhancing plant growth. However, only few studies have examined the application of PGPR in in-vitro plant micropropagation. This study was aimed at evaluating the effects of plant growth promoting rhizobacteria (PGPR) and hormone levels on in-vitro micropropagation of Peperomia. The experiment was conducted in a...

In order to assessment of relationships between effective traits on grain yield and also determination of cause and effect relationships between of them, 121 native and exotic cultivars available in the collection of Rice Research Institute of Iran were evaluated in a simple lattice design (11×11) with two replications for 12 important agronomic traits. The results of analysis of variance showe...

    In order to investigat e of Tobacco germplasm genetic diversity, 49 genotypes were grown in Tobacco Research Institute (Rasht, IRAN) as a simple lattice design 7×7 with 2 replications and 12 treatments were evaluated as well. Correlation analysis to studied traits showed that Fresh leaf yield with leaf number, leaf length, leaf width, leaf area index, plant height, flowering period and days...

In order to study the effects of foliar spraying of Pseudomonas fluorescens bacteria on quantitative characteristics, yield and yield components of two rice cultivars, a factorial experiment, based on completely randomized design with three replications, was conducted in Rice Research Institute of Rasht, Guilan province, Iran. In this experiment, two rice cultivars (Khazar and Hashemi) were spr...

the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...

In order to identify QTLs controlling agronomically traits, landrace Tarom and rice Tarom mutant were crossed. SSR, ISSR, iPBS and IRAP markers were amplified in 250 F2 individuals to prepare the linkage map. Number of tillers, 100 grain weight, number of filled grains, number of unfilled grains, plant height, panicle length, number of branches, stem diameter, grain length, grain width, grain s...
