Storage for one year at -3°C in the case of the seeds dried after harvest to the moisture content of 10% does not reduce their germination capacity. Stones scarification in concentrated sulphuric acid for 120 minutes followed by stratification at 3°C has an adverse effect on seed emergence...
Results showed a higher percentage of seed germination using alternate temperature stratification than for the constant temperature stratification regime. These results suggest that PGPRs in combination were effective in terms of promoting germination of C. pseudoheterophylla seeds....
Germination was enhanced in seeds from a lower altitude provenance. These results suggest that the application of polystimulins followed by alternating temperature stratification (both warm and cold stratification) is effective at breaking the dormancy of hawthorn seeds....

Seed dormancyStratificationWater uptakeGermination rates of Crataegus pseudoheterophylla are low and may be restricted by the presence of a hard endocarp and embryo dormancy. We examined the effects of pectinase [0, 0.5, 1, or 2% (w/v)], benzylaminopurine (BAP) (0, 100, 200, 400, or ...
