摘    要:采集阿尔泰山楂、准噶尔山楂、红果山楂成熟的种子分别采用湿种恒温、变温、外源激素浸泡处理、阴干后层积方法进行层积处理测其种子特征指标及层积后的发芽率,结果表明变温层积对两种山楂种子的萌发有较好的促进作用但不同种山楂种子所需的较适层积时间范围有差异阿尔泰山楂种子层积日90d左右发芽率可达39.5%,红果山楂种子层积150d左右发芽率可达27.1%;准噶尔山楂种子在所有层积处理中的萌发率都相对较低100mg/L的GA3处理层积180d后发芽率为10.2%,三种山楂种子均为自然休眠种子不同层积处理能够打破其休眠促进种子萌发其中变温层积处理效果较好,阿尔泰山楂具有较高的发芽率.

关 键 词:野生山楂  种子特征  层积处理  萌发

Abstract:The purpose of this research was to explore the ripening seeds of the wild hawthorn, such as Al tai ha wthorn ,.1 unggar IIa w thorn and era happle ha wthern , which were treated with different s trat ifica tior inc! uding , wet-seed constant temperature stratification, terriperat ure change st ra tifica tion , normone immersion processing, the stratification method after drying. The result showed that temperature change stratification could promote the germination rate of the two ha wt hern seeds but there were differences in time range of better suitable stratification needed for different hawthorn seeds sthe germination rate of the seeds of Altai hawthorn can reach 39.S% when the stratification for 90 d ; The germination rate of the seed of the crabapple hawthorn can reach 27.1 % when the stratification for ISO d. The germination rate of .lunggen hawthorn seed was relatively low, the germination rate was only 10.2 % after the treatment of 100 mg/L of GA. and the stratification for 180 d.Different stratification can break the dormancy and promote germination rate of wild hawthorn seedvand the effect of processing of variable temperature stratification is better. The seed of Altai hawthorn has the higher germination rate.
Keywords:wild hawthorn  seed characteristics  stratification  germination
