| 中文摘要: |
| 为探讨椒样薄荷耐盐生理特性，为其在盐渍地的开发利用提供理论基础，研究了不同浓度NaCl 胁迫对
椒样薄荷生长及抗氧化系统的影响。结果显示，在100、150 mmol/L NaCl 胁迫下，椒样薄荷能够正常生长，植株通过
提高抗氧化酶（SOD，POD，CAT，APX）的活性以及抗氧化物质（AsA，GSH，carotenoid）的含量，在一定程度上缓解NaCl
胁迫引起的氧化损伤，但是随着NaCl 浓度（200、250 mmol/L）的提高，椒样薄荷抗氧化酶活性和抗氧化物质含量随
NaCl 胁迫时间的延长先上升后下降，生长受到较大影响。这表明椒样薄荷能够耐受150 mmol/L NaCl 胁迫，在该浓度
下，薄荷植株能够正常生长，具有较强的活性氧清除能力，而在遭受更高浓度NaCl胁迫时会受到一定程度的伤害。 |
| 英文摘要: |
| SPNE (Special Plant Nutritional Element) was sprayed one or two times, and the effects of spraying time on
amylase activity and yield of late flowering cabbage were studied comparing with the control spraying with water. Serial
analysis between the seeds of twice SPNE spraying and the control was done to test the effect of SPNE epigenetic effect of
SPNE on the peroxidase activity of progeny seedling. The results showed that amylase activity as well as the yield of the
late flowering cabbage increased significantly after spraying SPNE along with the increase of spray times, and the both
indexs exihibited higher in twice spraying than in once spraying. Correlation analysis results also showed a positive
correlation between the amylase activity and the yield of late flowering cabbage. Comparing with the control, the yield,
1000-grain weight, germinative force and vitality for cabbage seeds increased significantly after twice spraying, as well as,
the leaf area became larger, the root system developed better, the peroxidase activity improved obviously, showing stronger
for stress resistance and better for growth vigor. The mechanism of the effect of SPNE on late flowering cabbage was further
studied in this paper. |
