摘　　要：通过定株、定期对14个黑莓、树莓品种的物候期进行观察,基本掌握了各品种在南京地区的物候期和各生育期维持的时间,为其优良品种的推广利用提供了依据。调查结果显示:不同品种黑莓与树莓各物候期存在差异,总的来看,黑莓品种一般在2月中下旬萌芽,3～4月展叶,4月中下旬至5月中下旬开花,花期平均(28.67±5.98)d,5月坐果,果实6月上旬至7月上中旬成熟,果熟期(28.78±6.44)d;树莓品种多集中在3月上中旬萌芽,4月下旬至5月上旬开花,果实5月下旬至6月下旬成熟。Based on investigation on fixed plants and phases of 14 varieties of blackberry and raspberry, the phenophase and development periods were obtained to provide evidence for the extension of fine varieties in Nanjing areas. The results showed that the phenophase were different between varieties of blackberry and raspberry. Generally, the blackberry varieties were sprouted from early ten days to middle of Feb, leaf expansion from Mar to Apt, flowered from middle ten days of Apr to last ten days of May. The average florescence was 28.67 days （ ± 5.98）, the fruits were set during May and the fruit mature wasfrom early ten days of Jun to middle of Jul, lasted 28. 78 days （ ± 6. 44）. While most of raspberries were sprouted from early ten days to middle of Mar, flowered from last ten days of Apr to early ten days of May, and the fruit mature was from last ten days of May to Jun.
