摘要：通过对甘肃当归(Angelica sinensis(Oliv.)Diels.)主产区4个县31个生态区种植的二年生岷当归长势及早期抽薹率的田间调查,旨在探寻海拔、经度和纬度对岷当归成药期生长及早期抽薹的影响,为确定当归的适宜生态区提供理论依据。结果表明:地理位置对当归早期抽薹和长势均具有显著影响,变异程度从高到低依次为抽薹率>株高>叶片数。株高、叶片数和抽薹率与海拔高度和经度均呈极显著负相关,而与纬度均呈显著极显著正相关。多元回归分析表明,株高、叶片数和抽薹率均与海拔间存在显著直线回归关系,说明海拔是影响当归植株长势和早期抽薹的主要生态因子,高海拔区种植的当归植株明显矮化,抽薹率显著降低。
Based on field investigations of growth and early bolting rate of biennial angelica cultivated in 31 ecoregions of 4 counties of Gansu Province,the effects of altitude,longitude and latitude on angelica growth and early bolting at medicine formation period were investigated to provide theoretic evidence for determining Angelica planting ecoregion properly.Results showed significant geographical effects on both early bolting and growth of Angelica.Heteromorphosis was classified into following rank order： bolting rateplant heightleaf numbers.Plant height,leaf numbers and bolting rate had significantly negative correlations with altitude and longitude.However,all were significantly positive for latitude correlations.Multiple regression analysis showed that plant height,leaves and bolting rate had significant linear regression relationships with altitude.Results showed altitude as the main ecological factor influencing angelica growth and early bolting.Both height and bolting rate of angelica plants decreased significantly in high altitude areas.
