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% ...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...
This experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (Triticum aestivum L.) and durum (Triticum turgidum L.) wheats in seedling stage. A greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. Different agronomic and physiol...
Hormonal priming to overcome drought stress and aging damage in groundnut seed (Arachis hypogaea L.)
Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...
The introduction of nanoparticles into seed germination and seedling growth of plants might have a significant impact and thus, it can be used for agricultural applications for better growth and yield. The purpose of this study was to compare the effects of silica and silver nanoparticles on seed germination and early growth traits as well as percent and rate of germination, root length, shoot ...
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...
root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...
In order to evaluate the salinity tolerance of oat genotypes (Avena sativa L.), at seedling and reproductive stages, an experiment with three replications was carried out in greenhouse condition (based on Randomized Completely Design). Experiments were carried out in research field of Esfahan University of Technology. which is located in Lourk’s Najafabad without stress, EC=4 ds/m, as well as ...
In the present study, toxic effects of glyphosate on Allium cepa L. (Amaryllidaceae) cells were investigated. For this aim, we used the germination percentage, root length, seedling weight, malondialdehyde (MDA) level, frequency of micronucleus (MN), chromosomal aberrations (CAs) and mitotic index (MI) as indicators of toxicity. In addition to the analyses mentioned above, we also examined chan...
