摘要: 为探明硃砂烟在不同施肥量处理下碳氮代谢和生物碱含量的变化规律,以硃砂烟3号为试验材料,于2020年开展大田试验。结果表明:减肥15%处理下烟株的硝酸还原酶、谷氨酰胺合成酶活性低于增肥15%处理烟株,说明减肥15%处理下烟株的氮代谢不如增肥15%处理烟株旺盛。在旺长期、下部叶成熟期和中部叶成熟期,减肥15%处理下的烟株蔗糖合成酶(SS)活性显著低于增肥15%处理,说明减肥15%处理烟株碳代谢产物量少于增肥15%处理烟株,碳代谢强度更低。减肥15%及当地常规处理下的烟碱含量低于增肥15%处理,但在增肥15%条件下,降烟碱含量最低。

Abstract:

To investigate the effects of different fertilization dosage on carbon-nitrogen metabolism and alkaloid content in Zhusha tobacco, a field experiment was conducted in 2020 using Zhusha tobacco 3 as the test material. The results showed that the activities of nitrate reductase and glutamine synthetase in tobacco plants under the 15% fertilizer reduction treatment were lower than those under the 15% fertilizer increase treatment, indicating that nitrogen metabolism was less vigorous in the 15% fertilizer reduction treatment compared with the 15% fertilizer increase treatment. During the vigorous growth period, lower leaf maturation period, and middle leaf maturation period, the sucrose synthase activity in tobacco plants under the 15% fertilizer reduction treatment was significantly lower than that under the 15% fertilizer increase treatment, suggesting that the carbon metabolism products were less abundant and the carbon metabolism intensity was lower in the 15% fertilizer reduction treatment. Under the 15% fertilizer reduction and local conventional treatments, the nicotine content was lower than that under the 15% fertilizer increase treatment, but under the 15% fertilizer increase condition, the nornicotine content was the lowest.

Key words: different fertilization dosage, Zhusha tobacco, carbon-nitrogen metabolism, alkaloids
