understanding the seed germination response of cultivated genotypes to temperature is important, agronomically. the genotypes that germinate in lower temperatures could be useful for situations (such as late winter plantings) where temperatures are low in germination stage. therefore, this experiment was conducted to study the cardinal temperatures, response to sub- or supra-optimal temperature...
sod culture is one of the important methods in establishing and repairing of turf grass, especially in sport fields. nowadays, a mixture of sand and peat are commonly used in sod production in iran. because peat media is expensive, it seems necessary to find an alternative medium. rice hull, tea waste and leaf compost as economical organic material that are available in huge loads in north of i...
Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...
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...
Seed priming is a common way to increase the speed and uniformity of germination under Under stress and non-stress conditions. The aim of this study was to investigate the effects of different levels of gibberellic , salicylic and ascorbic acid on improvement of germination indices of Zygophyllum atriplicoides under salt stress in laboratory Chemical stimulators used in this study include: 3 le...
Seed quality is one of the most important factors affecting seed germination and seedling growth. In order to investigate the effects of seed aging on germination and seedling growth of sunflower cultivars, a factorial experiment was conducted based on a completely randomized design with three replications in seed research laboratory of Shirvan Higher Education Complex. To create 7 different tr...

This study was conducted to evaluate the effect of hydropriming and seed aging on germination and enzymatic properties of pinto bean under salinity stress as factorial based on a completely randomized design with four replications. Two groups of seeds (i.e., non-aged and aged seeds), two hydropriming treatments (i.e., hydro primed and unprimed seeds) and six salinity treatments (i.e., 0, 2, 4, ...
In order to study the effects of different levels of salinity on germination components of wheat cultivars, a factorial experiment was conducted based on a completely randomized design with three replications. Experimental factors were wheat cultivars at eight levels (Saysons, Gaspard, Finkan, MV-17, Chamran, Sardari, Atila-4 and Azar-2) and six levels of salinity (0, 25, 50, 100, 150 and 200 m...
Due to the importance of medicinal plants, understanding the seed germination response to temperature is agronomically important. A laboratory study was conducted to investigate the effect of different temperatures on seed germination of fennel, cannabis and sesame in a completely randomized design with four replications. Various constant temperatures (5, 10, 15, 20, 25, 30, 35 and 40°C) we...
