摘要: 为探明由于经纬度及海拔等地理要素差异对烤烟种植产生的影响,选择云南省大理州弥渡县和祥云县、玉溪市红塔区为试验点,以烤烟品种‘红花大金元’为试验材料,对比分析3地气候条件,δ13C、光合色素、抗性生理特征及化学成分等指标。结果表明,制约烤烟种植的气候要素尤以气温为甚,弥渡与祥云相比,光合色素差异不明显,类黄酮含量及δ13C较高,比叶重差异显著;对比1生理特征变化趋势与对比2类似。从化学成分协调性比较,弥渡烟叶的化学成分较好,祥云及大营街次之,但两地较为接近。对3地烟叶与植烟土壤δ13C的比值进行排序,以弥渡的比值最大,说明弥渡的生态环境最有利于‘红大’的种植。研究以δ13C值为核心,从一个侧面初步解析了‘红大’品种得以在大理州广泛种植的生态原因。

Abstract: In order to investigate that the differences of geographical, such as latitude and longitude and altitude, impact on tobacco planting, Midu County and Xiangyun County ,which in Dali , Camp Street in Yuxi were selected for the test point. The climate conditions, leaf stable carbon isotope composition (δ13C), photosynthetic pigments, resistance physiological characteristics and chemical composition were analyzed. The experiment showed that: temperature is the most important factor to influence flue-cured tobacco. Compared with Xiangyun and Midu, photosynthetic pigment have no obvious differences, Midu’s flavonoid,δ 13 c and LMA is higher. The variation trend of physiological characteristics on Midu and Camp Street is similar with Midu and Xiangyun. Compared the chemical composition of coordination, the Midu’s tobacco chemical composition is better, Xiangyun and Camp Street followed by, but the two are closer. On tobacco and soil’s δ13C ratio for sorting, still Midu's maximum, so Midu ecological environment is the most conducive to Honghuadajinyuan planting. The δ13C is the core of this experiment, and preliminary explanation that why Honghuadajinyuan are widely cultivated in Dali.
