摘要
以南岳树木园内5个杜英科树种为材料,研究分析了树种气候生态与物候的主要特征。结果表明树木的展叶始期活动积温都出现在300℃以内,树木始花的活动积温大多在2500℃以内。果成熟期有二种,一是当年结果当年成熟;二是当年结果翌年果熟如冬桃。这为5种树木在栽培育种及园林应用上提供基础依据。
The phonological characteristics of 5 tree species such as Elaeocarpus chinensis, E. glabripetalus, E japonicus,E. duclouxii ,Sloanea sinensis among Elaeocarpaceae were studied in the Botanical Barden of Hengshan Mountain in this paper. The results showed that the active accumulated temperature at beginning of leaf expansion and at beginning of flowering for all 5 tree species was below 300℃ and 2500℃, respectively. There are two forms of fruit maturating; one is that the fruits maturated in current year, another in the following year, such as E. duclouxii. These results would be helpful for the seedling breeding and application in landscape.
