【摘要】 试验于2010年和2011年在贵州省开阳县龙岗镇烤烟良种繁育基地进行,设置3个不同植烟区土壤处理(天柱砂壤土、威宁粉壤土和龙岗壤黏土),研究相同气候条件下贵州不同区域植烟土壤对烤烟中上部叶抗氧化系统及烟叶外观质量和感官质量的影响。结果表明:烤烟生长发育中期,天柱砂壤土和威宁粉壤土处理烟叶多酚氧化酶、超氧化物歧化酶及过氧化物酶活性较高,后期龙岗壤黏土处理较高;烤烟生长发育中后期,天柱砂壤土和威宁粉壤土处理烟叶丙二醛含量均高于龙岗壤黏土处理,因此,天柱砂壤土和威宁粉壤土处理烟叶进入成熟衰老的时间较龙岗壤黏土早。天柱砂壤土处理烟叶外观质量和感官质量均较好,其次是龙岗壤黏土,威宁粉壤土较差。天柱土利于优质烟叶的形成。更多还原

【Abstract】 An experiment was conducted at the flue-cured tobacco breeding base in Longgang Town Kaiyang County of Guizhou Province in 2010 and 2011. Three soils of Tianzhu sandy loam(TZSL), Weining silty loam(WNSL) and Longgang clay loam(LGCL) were set under the same climatic condition to study the effects of different soil types on antioxidant systems in middle and upper leaves in the medium and later term of tobacco plant growth and development and appearance quality, sensory quality after first baking. The results showed that, the activities of PPO, SOD and POD in TZSL and WNSL were higher at the medium term of tobacco plant growth and development, the effects of LGCL became more obviously important during the latter stage of growth. The contents of MDA in middle leaves and upper leaves in TZSL and WNSL were higher than that of LGCL. The appearance quality and sensory quality of flue-cured tobacco in TZSL were best, followed by LGCL and WNSL. The time of entering ripening and senescence period in TZSL and WNSL were earlier and LGCL was later, TZSL is conducive to becoming of high-quality tobacco leaves.更多还原
