Osmotic stress is the most important of the abiotic stresses that lead to limitation of growth and yield in rapeseed. This study was conducted to examine the effect of cycocel seed priming on osmotic stress tolerance in germination and early growth stages of rapeseed, as a factorial experiment based on completely randomized design at Agriculture College of Shiraz University in 2012. The treatme...

Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...

To study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (Zea mays L.),two experiments were separately conducted at Shahrood University of Technology. Seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofCaCl2 for 16 h (halopriming). Germination and early seedling gr...

despite the importance of drought stress in early stage of growth and plant establishment, it has usually been neglected as selection criteria in breeding programs. therefore, a population of recombinant inbred line derived from the cross “babax/seri m82” and their two parents were studied. the experiment was conducted in two randomized complete block designs with two replications under osmotic...

To evaluate the effect of priming on seed germination of Cucurbita pepo in drought stress conditions, a factorial experiment was conducted as completely randomized design with three replications. Treatments included drought stress at five levels of osmotic potential (zero, 0.3, 0.6, 0.9 and 1.2 MP), priming at levels of GA3 (250 ppm to 24 hours), KNO3 (0.2% for 24 hours) Hydro prime (H2O) (to 2...

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- 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...
