Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010/2011 and 2011∖2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield of maize. Maize seeds were treated with Bacillus megaterium (V16), Pseudomonas sp. (StB5, A3, A6, and A61), Burkholderia ambifaria (V9), Entero...
Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...
It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...
Low and uneven germination is a serious problem for the successful production of okra seedlings. Priming seeds as well supplementation different plant growth regulators exhibited better response in seedling which eventually results higher yield. Therefore, present study was conducted to evaluate effects seed priming exogenous application salicylic acid (SA) on development. The were primed by 1 ...
Seed priming was carried out to determine the effect of different agents on seed germination and growth landraces lentils. The two factorial experiments were in a completely blocked design which one is 7 treatments, i.e., PEG (10%), Boric acid (0.1%), Urea (2%), (5%), DAP CaCO3 (2%) & Control. Other landraces, Sunwarshi-LR1 Rangeli-LR2, collected from locations Morang district, replicated t...
In order to investigate different treatment effects on germination in Gundelia tournefortii, three factorial experiments were carried out in the completely randomized design with three replications. The first factor was stratification at 4oC in three levels including 0, 3 and 6 weeks, the second factor was mechanical scarification in two levels including seeds with/without scarification and the...
DOR: 98.1000/2383-1251.1397.5.71.9.1.1575.1605 Extended abstract Introduction: Generally speaking, plants contain various organic compounds which could influence the behavior of plant communities. These compounds are basically secondary metabolites which are found in various parts of plants such as rhizomes, roots, stems, leaves, flowers, fruits and seeds. The objective of the present st...
Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...
Identification of medicinal plants with tolerance to salinity stress has an economical importance in Iran. This study was carried out to evaluate the effects of salinity stress on different Morpho-Physiological traits of Foeniculum vulgare Mill in germination and seedling stage in hydroponic condition. The experiment was conducted as a split plot based on a Randomized Complete Block Design (RCB...
