通过对１９９４年和１９９５年采收的山楂种子进行层积、发芽、组织培养、生活力测定、ＧＡ３处理等多种方法进行研究认为，层积中山楂种子先解除休眠而后破壳；种子子叶休眠时间短，并可在干藏条件下解除休眠，休眠解除后，种皮抑制其生长；在种子发育过程中，子叶进入休眠前，种皮对子叶生长有一定作用；干藏７个月以内的种子，去除种皮或去除种皮及子叶，胚芽、胚轴、胚根不能萌发 According to the results of stratification, germination, tissue culture, viability measurement and GA3 treatment of the hawthorn seeds collected in 1994 and 1995, it is considered that the hawthorn seeds in the stratification are relieved of dormancy and then broken shell; seed cotyledons dormancy The time is short and the dormancy can be released under the conditions of dry storage. After the dormancy is lifted, the seed coat inhibits its growth. During the seed development, the cotyledon before dormancy, the seed coat has a certain effect on the growth of cotyledons; dry storage within 7 months Seeds, removal of seed coat or removal of seed coat and cotyledons, germ, hypocotyl, radicle can not germinate
