Abstract In order to study the germination rule of Acer grosseri Pax seeds from different provenances, the germination test of Acer grosseri Pax from different provenances was carried out by temperature, storage method and storage time. The results showed that the germination rate of Acer grosseri Pax seeds was very low under 5 ℃low temperature. With the increase of temperature, the germination rate of seeds from different provenances had significant difference;4 ℃low temperature wet sand storage can significantly improve the seed germination rate of Acer grosseri Pax,under the same storage conditions, there were significant differences in seed germination rate among different provenances, under different storage conditions, the germination rate of the seed was higher in Pinglu County, Shanxi Province, and lower in Taibai County, Shaanxi Province; wet sand storage at 4 ℃for 80 days could significantly increase the seed germination rate of Acer grosseri Pax from different provences,the seed germination rate of Pinglu County of Shanxi Province, Gujiao City of Shanxi Province and Tongchuan City of Shaanxi Province were significantly different under different storage time conditions, but not at other provenances.

葛蘿槭(Acer grosseri Pax),槭樹科,槭屬,落葉喬木,喜陰,果實為黃色或紅色翅果,樹皮青綠色,葉在秋季為黃色或紅黃色,分布于海拔800~1 600 m疏林中[1]。我國是世界上槭樹種類最多的國家之一,已知有151種,全國各地均有分布,主產(chǎn)黃河中下游各?。?],多以種子進(jìn)行繁殖,種子具有明顯的休眠習(xí)性[3]。梁鳴等[4]研究表明,低溫處理是解除槭樹種胚休眠最有效的方法之一。任明瑩[5]對加拿大糖槭進(jìn)行冬季預(yù)先處理60 d,可提高糖槭種子的萌發(fā)率。喻才員等[6]研究發(fā)現(xiàn),經(jīng)過低溫層積14 d處理,可有效打破青榨槭種子的休眠?!?br>
