摘要: 摘 要:通过大田试验研究了水氮耦合对烤烟中性致香物质成分含量的影响。结果表明,除不同灌水量对棕色化反应产物含量的作用效果不显著外,不同灌水量、施氮量以及二者交互作用对各类致香物质成分均有显著的影响;类胡萝卜素类降解产物、新植二烯含量在灌水量450m3/hm2达到最大值,棕色化反应产物、类西柏烷类降解产物含量在灌水量0~900m3/hm2范围内随灌水量的增加表现出先降低又增加的趋势。中灌水量(w2)处理中类胡萝卜素类降解产物、苯丙氨酸类代谢产物、棕色化反应产物、新植二烯含量随施氮量的增加而增加,类西柏烷类降解产物含量在施氮52.5 kg/ hm2时达到最大值。

Abstract: Abstract:The interaction effects of water and nitrogen on the neutral aroma component of tobacco were studied by field experiment. The result showed that different irrigation, nitrogen application and their interactions on aroma component had reached a significant level except the effect of different irrigation to browning reaction substance. The content of products degraded by carotene and Neoplytadiene had reached the highest level at the irrigation of 450m3/hm2 .The content of browning reaction substance and products degraded by cembrane had increase firstly and then dropped at the irrigation range of 0~900m3/hm2. The content of products degraded by carotene, products degraded by phenylalanie, browning reaction substance and neoplytadiene had increased with the nitrogen application at mid irrigation (W2) treatment, the content of products degraded by cembrane had reached the highest level at the nitrogen application of 52.5 kg/ hm2. Keywords: irrigation; nitrogen application; interactions; neutral aroma component.
