Study on Seed Germination Rule of Acer Grosseri Pax from Different Provenances
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 A-cer 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 Prov-ince;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 sig-nificantly different under different storage time conditions,but not at other provenances.
