in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

Summary The quality and provenance of seed are exceptional importance for the production yield cultivated plants. There numerous tests determination vigour. accelerated ageing test is one most important that provide degree germination preservation longevity in storages. aim this study was to observe effect different methods – organic conventional on vigour maize (variety Rumenka), using test. M...

this research was conducted in order to evaluate genetic diversity, and screening the tolerant genotypes of sugar beet subjected to continuous and severe water stress in the experimental farm of sugar beet seed institute (sbsi) in karaj in 2008. the experimental design was a randomized complete block with 6 replications. fifteen o-types which were tolerant to drought plus 5 (check) genotypes we...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...

Previous energy-dispersive x-ray analysis studies of globoid crystal composition in seed protein bodies gave an indication that there might be a correlation between seed size and the type of elements stored in globoid crystals. This possibility was tested by conducting energy-dispersive x-ray analysis studies of P, K, Mg, and Ca levels in globoid crystals of four embryo regions (radicle, stem, ...

BACKGROUND AND AIMS Imbibition of Japanese soybean (Glycine max) cultivars was studied using micro-magnetic resonance imaging (MRI) in order to elucidate the mechanism of soaking injury and the protective role of the seed coat. METHODS Time-lapse images during water uptake were acquired by the single-point imaging (SPI) method at 15-min intervals, for 20 h in the dry seed with seed coat, and ...

salicylic acid (sa) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. it has been recognized as an endogenous regulatory signal in plants. in order to study the effect of different concentrations of sa on germination, growth and some physiological parameters in chickpea (cicer arietinum l.) two genotypes (mcc414, mcc361) under drought stress conditions, ...

Objective: To evaluate ten triticale genotypes to assess the quality of seeds under two production systems, with cut and without cut, in municipalities Matamoros (L1) Francisco I. Madero (L2), Coahuila,Mexico.Design/Methodology/Approach: The agronomic variables evaluated were: Grain yield (GY), number per spike (NSS), length (SL), spikelets (SS) plant height (PH). Variables laboratory normal se...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...
