| 通过盆栽试验,研究了不同有机酸对不同成熟度烤烟生理代谢与营养代谢的影响。结果表明,适熟时,苹果酸、油酸和腐殖酸均能明显降低烟叶中细胞膜脂过氧化程度,提高烤烟抗衰老能力和抗逆性,有利于烤烟的生长;有机酸能不同程度地提高烟叶总糖、还原糖和烟碱含量,其中,苹果酸还能明显提高中部和下部叶中K素含量;过熟时,油酸处理烟叶的抗逆性明显增强;同时苹果酸和腐殖酸能明显提高上部叶K素的含量,苹果酸和油酸能明显提高总糖和还原糖的含量,而油酸则能明显降低淀粉和烟碱的含量。 |
| 英文摘要: |
| Apot trial was conducted to systematically study the effects of malic acid oleic acid and FA on maturity physiological and nutrition metabolism of flue-cured tobacco．The main results were as follows：During the ripe harvesting time the three organic acids could obviously reduce velum lipid peroxidation degree of tobacco leaves and could obviously improve the resistance of flue-cured tobacco which was in favor of promoting the growth of flue-cured tobacco. Simultaneously the three organic acids could improve total sugar reducing sugar and nicotine contents of tobacco leaves in different degree．Malic acid could obviously increase the K content of the middle and lower stalk position leaves．During the over-ripe harvesting time in comparison with the ripe harvesting time malic acid and FA could obviously increase the K content of the upper stalk position leaves. At the same time malic acid and oleic acid could obviously increase total sugar and reducing sugar contents of tobacco leaves．Oleic acid however could obviously reduce the starch and nicotine contents of tobacco leaves and could remarkably strengthen the ability of resisting senescence and raise the ability of resisting adversity. |
