To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...
Long non-coding RNAs(lncRNAs) are longer than 200 nucleotides in length, which largely exist in organism and have various biological functions. AtR8 RNA is a lncRNA transcribed by RNA polymerase III in Arabidopsis. Northern blot analysis indicates that AtR8 RNA is abundant during seed germination. AtR8 RNA partial deletion reduces seed germination under normal culture condition. SA treatment in...
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...
There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...
Priming of seeds by magnetic fields (magneto priming) is proposed as an ecological, useful and low-priced method for improvement of seed germination and plant emergence. In order to evaluate the germination behavior of sesame seeds affected by magnetic fields, an experiment was conducted as a completely randomized design with 22 treatments (non-exposure to magnetic fields (control) and 21 magne...
Smyrniopsis aucheri BOISS is an herbaceous species of Apiaceae family which seed germination is difficult. Therefore, to restore the natural habitats of this plant, it is necessary to provide information about the length and the factors that affecting seed dormancy of this plant. In order to study effect of the duration of chilling and temperature on seed dormancy and seedling establishment of ...
Soybean is an important and staple oilseed crop worldwide. Salinity stress has adverse effects on soybean development periods, especially on seed germination and post-germinative growth. Improving seed germination and emergence will have positive effects under salt stress conditions on agricultural production. Here we report that NaCl delays soybean seed germination by negatively regulating gib...
P. aegyptiaca is one of the most destructive root parasitic plants worldwide, causing serious damage to many crop species. Under natural conditions P. aegyptiaca seeds must be conditioned and then stimulated by host root exudates before germinating. However, preliminary experiments indicated that TIS108 (a triazole-type inhibitor of strigolactone) and fluridone (FL, an inhibitor of carotenoid-b...
Both red light (10 minutes) and 35 degrees C treatment (60 minutes) stimulate the germination of seeds of Rumex obtusifolius otherwise maintained in darkness at 25 degrees C. Fluence response curves were determined for the effect of red light to stimulate germination of seeds with and without 35 degrees C treatment. The endogenous far-red absorbing form (Pfr) level in the seeds was determined u...
In order to evaluate the effect of seed priming on some effective physiological parameters on seed germination of pea (Pisum sativum L.) under chilling stress, a factorial experiment was conducted in completely randomized design with four replications. Treatments were consisted of priming treatments (hydropriming, halopriming, osmopriming and no priming) and temperature (3, 6, 9, 12 and 15 ˚c)....
