Physiological and biochemical changes during sunflower seed deterioration were studied during incubation for 2, 4, 6 and 8 days at 43 °C and a relative humidity of 100%. Parameters such as germination percentage, germination rate, seedling length, seedling vigor and protein decreased whereas electrical conductivity, fatty acids and lipid hydroperoxides increased during seed deterioration. Incre...
The genus Thymus is perennial medicinal plants belong to the Lamiaceae familythat is used for different propose in pharmaceutical industry. Environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. The purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...
Ferula ovina is one of forage species of Isfahan and Chaharmahal va Bakhtiari whose natural spreads are under destruction. Finding information about its seed dormancy, effective factors in the dormancy breaking and also about optimal conditions of seed germination is necessary for recovery of this plant spreads. To actieve that goal, two factorial experiments were performed in completely random...
Poor germination and low seedling growth of stevia are common problems in the cultivation of the plant. Nutri-priming is a newest, safe, easy, and effective method to increase germination characteristics and seedling tolerance against stress. The objective in this study was to assess the effect of nutri-priming with nano potassium (nano-K), paclobutrazol (PBZ), and salicylic acid (SA) on stevia...
Abstract Salinity is one of the most important factors limiting plant growth and production around the world. Gibberellic acid is known as a strong growth stimulator, effective on seed germination and breaking of seed dormancy in various plant species. In order to study the response of Safflower,Sofeh cultivar, to salinity stress, a factorial experiment was conducted based on a randomized...

In order to evaluate the effects of seed priming with salicylic acid (SA) (0, 2, 10, and 20 mM) to increase salt tolerance (0, 50, 100, 150, and 200 mM NaCl) in medicinal plant Dracocephalum moldavica at seed germination, an experiment was conducted as factorial in a completely randomized design with four replicates. The assessed parameters included germination percentage and rate, len...
ABSTRACT- Improper seed germination is a serious challenge for medicinal herbs under drought stress conditions in semi-arid and arid regions. A new group of plant growth regulators known as karrikins have been proved useful to improve seed germination in some plants. In this regard, the effects of karrikin on seed germination and vigor of three medicinals under drought stress were examined. See...
In recent years the use of allopathic effects on weed management seems to have attracted many professionals. In order to investigate the effect of aqueous extracts of Yarrow (Achilla wilhelmsii L.) and Habek mint (Mentha longifolia (L.) Huds) medicinal plant on germination indices of plantain, two experiments were conducted in completely randomized design with three replications in 2014 in the ...
environmental stresses especially drought stress affect on the different aspects of plant growth and cause decrease and delay in germination, decrease of aerial parts growth and decrease in dry matter production. in order to study the effect of drought stress on germination and seedling growth of roselle (hibiscus sabdarifa) medicinal plant, this experiment was conducted in a randomized complet...
