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...

a study was conducted to determine the optimum concentration of benzyladenie (ba) and gibberllic acid (ga3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of ba and ga3 on growth and development of gladiolus corm and cormels. the effect of ga3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...

seed dormancy is a temporary failure of a viable seed to germinate. various methods are used for breaking seed dormancy, depending on plant species and type of dormancy. three seed populations originated from esfahan, semnan and fars provinces were exposed to different seed dormancy breaking treatments such as mechanical and chemical scarification, humid chilling, ga3 and polyethylenglycol 6000...

dormancy of eastern dodder and african rocket seeds makes the controlof them very difficult in orchards and farms. in order to study the effective factors in dormancy breaking of these two weeds species, a factorialexperiment based on crd with three replications was conducted at the research laboratory of birjand faculty of agriculture in 2008 and 2009. treatments were: control, soaking in sulf...

Dormancy is one aspect of tuber physiological age that begins with potato tuber initiation. During dormancy, biochemical and physiological processes do occur but they do not trigger immediate morphological changes, yet these processes are relevant for the number of sprouts produced after breaking of the dormancy and for the growth vigour of the seed tuber. This review article reports that dorma...

Variation in dormancy thresholds among species is rarely studied but may provide a basis to better understand the mechanisms controlling population persistence. Incorporating dormancy-breaking temperature thresholds into existing trait frameworks could improve predictions regarding seed bank persistence, and subsequently species resilience in response to fire, climate change and anthropogenic m...

BACKGROUND AND AIMS In temperate woody perennials, flower bud development is halted during the winter, when the buds enter dormancy. This dormant period is a prerequisite for adequate flowering, is genetically regulated, and plays a clear role in possibly adapting species and cultivars to climatic areas. However, information on the biological events underpinning dormancy is lacking. Stamen deve...

henbane hyoscyamus reticulatus l. is a plant species in solanaceae family that seeds hardly germinate because of seed dormancy. in order to determine the best methods for seed dormancy breaking in henbane, a experiment was conducted as a completely randomized design with three replications. the treatments included moist pre-chilling (at 4 °c) for 7, 14, 21 and 28 days, combined treatment of gib...
