摘要: 以烤烟品种K326、云烟87、云烟97、红花大金元为试验材料,自然环境下种植。每个品种设置3个不同供氮水平进行品比试验,对生理成熟初期-工艺成熟期第11叶位烟叶δ13C值、比叶重、光合色素和化学成分进行分析研究。结果表明:同一气候环境不同施氮处理条件下,K326、云烟97两品种的δ13C均值均高于云烟87和红大,尤其是云烟97在3个处理中类胡萝卜素含量均偏高、比叶重最大。在低氮和中氮条件下叶绿素a含量也以云烟97含量最高。化学成分分析表明,云烟97的烟碱含量与参考值相比,含量适宜且偏高,总糖、还原糖含量、糖碱比及氮碱比均在适宜范围内,化学成分协调性总体较好。以烤烟δ13C值表述的环境和生理特征的偶联程度,对各品种烤烟光合色素水平、比叶重和化学成分差异进行评估,表现为云烟97显著优于其它3个品种,且其适生能力最强,在中氮水平下种植,可相对提高其产量和品质。3个不同施氮水平下烤烟δ13C值、生理指标和化学成分在品种间表现存在的趋同或差异,可为烤烟种植施氮水平和品种筛选提供参考。

Abstract: Taking Flue-cured tobacco K326, Yunyan87, Yunyan97 and Honghuadajinyuan as experiment materials, planted under natural environment condition with three different nitrogen treatments. The chemical composition of the 11th position tobacco leaves and their δ13C value, leaf mass per unit area and the photosynthesis pigment was analyzed. The results showed that the mean δ13C value of K326 and Yunyan97 with different Nitrogen treatment was higher than that of Yunyan87 and Honghuadajinyuan, particular the Yunyan 97. The tobacco alkali content of Yunyan97 was optimum among four varieties with low nitrogen treatments, moreover, the total sugar content, the reducing sugar content, the sugar alkali content and NIT/NIC of Yunyan97 were within optimum scope and in a good coordination. Evaluation on all of flue-cured tobacco was conducted according to the δ13C values describe, Yunyan97 had obvious advantage and stronger adaptive ability, which was suitable to plant under conventional fertilizer. The results could provide reference to fertilizer treatments and varieties selecting for flue-cured tobacco.
