摘  要：
试验调查了树莓夏秋两季结果型品种顶峰的生长发育和开花结实特性。结果表明:品种顶峰分别在同一年的夏季和秋季两次开花结果,每年的6月下旬到7月下旬2a生枝结果即夏季结果期,果实生长发育从开花到成熟需28d,采收期近1个月,结果后枝条自然枯萎死亡;顶峰的秋季结果期为8月中旬到9月末,结果部位为1a生枝的中上部,果实生长发育需36d,采收期长达46d,采收后11月初枝条进入休眠。顶峰1a生枝的长度在6月上旬和7月上旬增加迅速,7月中旬停止增加,粗度的快速增加集中在6月上旬和7月份,8月初粗度停止增加,2a生枝的长度和粗度都不增加。

摘  要：
The fall-bearing cultivar 'Summit' was used as material for studying the growth and reproductive development characteristics of the raspberry.The results showed that the fall-bearing cultivars 'Summit' had two bearing stages within one year.The biennial cane fruited,that was the Summer-bearing,from the end of June to the end of July every year,it needed 28 days from flowering to fruit maturity in summer,the harvest duration lasted nearing one month,then the cane came into withered.Summit fruited from the middle of August to the end of September at the middle and upper of primocane.It needed 36 days from flowering to fruit maturity in fall,the harvest duration lasted 46 days,it came into dormancy at the early of November.The cane of raspberry was biennial,the length of primocane of Summit grew quickly from the early of June to the early of July,and stopped at the middle of July.The cane diameter increased quickly at the early of June and July,stopped at the early of August.There was no change of height and diameter of the biennial cane.
