摘　　要：以襄汾县皂荚树为研究对象,对其物候期及生长规律进行了观测分析。结果表明:皂荚在3月中旬芽开始萌动,1周左右开始膨大,3月下旬到4月上旬为展叶期。清明节前后开始开花,花期持续10 d^15 d左右。皂刺的刺芽4月10号左右开始萌动,4月、5月为皂刺快速生长期。枝条从4月开始旺盛生长,叶片叶绿素、叶周长等指标在3月至7月总体呈增长趋势。5月中上旬皂荚进入果实生长发育期,果期可达6个月。10月下旬进入落叶期,约持续12 d.果实平均长、宽、厚、重量为23.7 cm,32.76 mm,13.02 mm,25.5 g,种子平均长度、平均宽度、千粒重为11.31 mm,8.43 mm,405.14 g.The phenology and growth regularity of Gleditsia sinensis in Xiangfen County were observed and analyzed.The results showed that the buds of Gleditsia sinensis began to germinate in mid-March and began to swell in about a week.Its leaf expansion period was from late March to early April.The flowers began to bloom before or after Qingming Festival and the florescence could last 10 d^15 d.The thorn bud of Gleditsia sinensis began to germinate in about April 10th,April and May were its rapid growth period.Branches began to grow vigorously from April.The chlorophyll and perimeter of leaves showed an increasing trend from March to July.Gleditsia sinensis entered the stage of fruit growth and development in mid-early May,its fruit stage could last for 6 months.In late October,Gleditsia sinensis entered the leaf fall period and lasted for about 12 days.The average length,width,thickness and weight of fruit were 23.7 cm,32.76 mm,13.02 mm,25.5 g.The average length,width and 1 000-grain weight of seeds were 11.31 mm,8.43 mm,405.14 g.
