deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...

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...

the allelopathic potential of different concentrations (0, 5 %, 10 %, 20 % and 40%) of medicago sativa shoot extracts were assayed on germination and radicle growth of four weed species( amaranthus hybridus, amaranthus albus, solanum nigrum and chenopodium album) in a laboratory experiment as completely randomized factorial with 3 replications. the results showed that, final germination percent...

in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

The dormancy characteristics and optimum conditions for seed germination of Alstroemeria ligtu had not been explained. In vitro and in vivo alstroemeria (A. ligtu hybrid) seed germination tests were conducted in a Randomized Completely Design at two different treatments (gibberellic acid (GA3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oC) in four replications. Seeds were pl...
