in order to the study of the salinity effects on seed germination and effecting parameter of fennel (foeniculum vulgare) was conducted a factorial experiment in a completely randomized design with two factors and three replications. factor a was 10 ecotypes, including; sardasht, saghghez, kerman, tabriz,sabzevar, rome, khusf, bojnoord, mashhad and shabestar and factor b was five concentrations ...
The main purpose of this research was to evaluate how duration and priming method may affect the germination and growth of cumin seed (Cuminum cyminum L.). The study was carried out in 3 replication by using a randomized completely block (RCB) design. The experimental treatments included: control, [hydro-priming in two durations of 24 and 48 h], [osmo-priming (0.2% of KNO3 in 24 and 48 h, 0.3% ...
Plant growth promoting rhizobacteria (PGPRs) are a group of bacteria that can actively colonize plant roots and can modulate plant growth. The present study was aimed to investigate the effects of three PGPRs strains designated as Pseudomonas fluorescens (PF23) and P. putida (PP-41 and PP-159) on seed germination features including germination percentage (GP), mean time germination (MTG), germi...
The present works were carried out to determine the impact of different municipal solid waste compost (mswc) soil extracts (Tap water, 5%, 10%, 15%, 20%, 25%, 30% and distilled water (control) obtained from mswc (degraded soil) and different mixing ratio of mswc and distilled water on the percentage of relative seed germination (RSG%), vigor index, root length, shoot length of soya bean (Glycin...
Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...
Extended abstract Introduction: Seed deterioration is associated with oxidative stress and uncontrolled accumulation of reactive oxygen species. Seeds have a group of enzymatic and non-enzymatic antioxidants that protect them against reactive oxygen species and help maintain seed vigor and support seed germination processes. The response of different cultivars to seed deterioration is differen...
seeds of most crops including those of range plants follow orthodox behavior. however, these seeds undergo aging even under favorable conditions, so that decreased viability and vigor related parameters are the main characteristics of deteriorated seeds. the effects of hormonal priming with auxin, cytokinin, gibberellin and abscisic acid at 0, 50, 100 and 150 ppm on physiological quality of tal...
the aim of this study was to investigate the allelopathic effects of eucalyptus camaldulensis on germination and early seedling growth of festuca arundinacea under laboratory condition in order to determine the effect of pretreatments on decreasing the destructive effects of allelopathic compounds. the chemical stimulators used in this study included 3 levels of gibberellic acid, 3 levels of sa...
