摘要
通过盆栽试验研究了不同用量的苹果酸对烟叶中非挥发性有机酸的影响,结果表明:处理1 g/L降低了上、中部叶,但提高了下部叶非挥发性有机酸总量,处理2 g/L和处理3 g/L对非挥发性有机酸总量影响不明显;苹果酸处理还可提高多元羧酸在非挥发酸中的比例,降低饱和脂肪酸和非饱和脂肪酸的含量及其在非挥发酸中的比例,且多元羧酸、苹果酸含量随着苹果酸用量的增加而增加.因此,施用苹果酸对改善烟叶质量有积极作用.
The paper studied the effects of applying malic acid with different amounts on nonvolatile organic acid in tobacco by potted plant. The result showed the treatment 1 g/L reduced the content of nonvolatile organic acid in upper leaf and cutters, but increased that of lower leaf. The treatment 2 g/L and 3 g/L did little significance. All the malic acids treatments increased the proportion of polypolidy carboxylic acid in nonvolatile organic acid. What＇s more, the more the amount of malic acid was applied, the higher the content of polypolidy carboxylic acid and malic acid were. All the malic acids treatments reduced the content and proportion of saturated fatty acid and None-Saturated fatty acid in nonvolatile organic acids. So applying malic acid took active effects on improving leaf quality.
