Plant Development: Multiple Strategies for Breaking Seed Dormancy
Plant seeds will not germinate when in a dormant state. What then are the factors controlling dormancy? A recent study has uncovered two basic-helix-loop-helix proteins which repress germination and are critical for maintaining dormancy. The combined action of light and cold synergistically alleviates activity of these repressors thus stimulating germination.
متن کاملA STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING
Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is 5˚C to 25 ˚C and optimal temperature is 15˚C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10˚C are better...
متن کاملSeed dormancy-breaking and germination requirements of
Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...
متن کاملseed germination response of medicinal plant alyssum (bracteatum) to dormancy breaking treatments
seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...
