Research on Seed Characteristics and Germination Features of Wild Hawthorn in Xinjiang

The purpose of this research was to explore the ripening seeds of the wild hawthorn,such as Altai hawthorn,Junggar Hawthorn and crabapple hawthern,which were treated with different stratification including,wet-seed constant temperature stratification,temperature change stratification,normone immersion processing,the stratification method after drying.The result showed that temperature change stratification could promote the germination rate of the two hawthern seeds but there were differences in time range of better suitable stratification needed for different hawthorn seeds,the germination rate of the seeds of Altai hawthorn can reach 39.5% when the stratification for 90d;The germination rate of the seed of the crabapple hawthorn can reach 27.1% when the stratification for 150d.The germination rate of Junggar hawthorn seed was relatively low,the germination rate was only 10.2%after the treatment of 100mg/L of GA3 and the stratification for 180d.Different stratification can break the dormancy and promote germination rate of wild hawthorn seed,and the effect of processing of variable temperature stratification is better. The seed of Altai hawthorn has the higher germination rate.
