- 摘要:
- 以金盏菊为试材，研究了不同浓度NaCl（40、80、120、160、200 mmol/L）胁迫对金盏菊生长和生理特性的影响。结果表明：在不同浓度NaCl胁迫下，金盏菊的株高、茎粗、叶片数、叶片和根的鲜重与干重、叶绿素含量、蛋白质含量和可溶性糖含量均呈先上升后下降的趋势，而根长和根体积呈逐渐下降趋势。表明金盏菊耐盐阈值80 mmol/L。
- Abstract:
- Taking Calendula officinalis seedlings as experimental material，effects of different contentration NaCl stress (40，80，120，160，200 mmol/L) on growth and development of Calendula officinalis were studied.The results showed that under the different concentration of NaCl stress，plant height，stem diameter，leaf number，leaf and root fresh weight and dry weight，chlorophyll content，protein content and soluble sugar content of Calendula officinalis showed a trend of falling after rising first，and showed a trend of gradual decline in root length and root volume，and showed that the calendula salt tolerance threshold value tendency for 80 mmol/L.
