| 摘 要： | 以油青60 天菜心为试材，采用叶面喷施方式，研究不同浓度的蔗糖处理对菜心可溶性糖含 量及产量的影响。结果表明：菜心薹茎中的可溶性糖、还原糖、果糖和葡萄糖含量均高于薹叶，而薹叶中 的蔗糖含量则高于薹茎。适宜浓度的蔗糖处理可显著地提高菜心可溶性糖含量，而过高浓度处理则抑制可 溶性糖的积累。叶面喷施50 mg·L-1 蔗糖可以极大幅度地提高菜心中的可溶性糖、还原糖、蔗糖、果糖和 葡萄糖含量。不同浓度的蔗糖处理对菜心单株产量影响均较小，处理间差异不显著。 |
| 关 键 词： | 菜薹（菜心） 叶面喷施蔗糖 可溶性糖含量 产量 |

| Abstract: | Using flowering Chinese cabbage（Brassica parachinensis Bailey）‘Youqing 60 tian’ as material，the experiment was conducted to investigate the effects of foliar application of different concentrations of sucrose on soluble sugar content and yield of flowering Chinese cabbage．The results showed that the contents of total soluble sugar，reducing sugar，fructose，glucose in the stems were all higher than in the blades，while the sucrose in the stems were lower than in the blades．Treatment of appropriate concentrations of sucrose could significantly increase the contents of soluble sugar in flowering Chinese cabbage，but high concentration treatment would inhibit the accumulation of soluble sugar．Foliar application of 50 mg·L-1 sucrose could remarkably increase the contents of total soluble sugar，reducing sugar，sucrose，fructose and glucose．Different concentration of sucrose treatment had little influence on the single plant yield. |
