摘　　要：在山西省平顺县刘家村试验地对2011年从甘肃、陕西、四川、山西等地引进的5个2年生花椒品种的物候期进行了观测,以当地花椒品种为对照,初步了解了这些品种在试验区的生物学特征和生态适应性,掌握了其季相变化规律,研究结果表明,花椒物侯期的变化与自然环境因子密切相关;各品种在4月初萌动,4月中旬发芽,4月下旬至5月上旬叶片开始脱落;所有品种中狮子头的物候期明显较其它品种滞后6 d^12 d,其它品种的物候期无较大差异。Biological characteristic and ecological adaptability of five 2 a varieties which were introduced from Gansu, Shaanxi, Sichuan, Shanxi in 2011 and local variety of Zanthoxylum bungeagum Maxim as control study planted in Liujia village in Pingshun county in Shanxi were observed. Seasonal change rule of them was understood. The results showed that phenological period change of Zanthoxylum bungeagum was closely related with natural environmental factors; all veriety buded in early Aprial, germinated in mid-Aprial and leaf dropped from late Aprial to early May; the phenological period of Shizitou laged 6 d - 12 d compared with other variety whose difference was not obvious.
