壳聚糖对玉米种子萌发及耐旱性的影响

以不同浓度的壳聚糖处理玉米种子,结果表明,以浓度150 mg/L的壳聚糖处理玉米种子可以获得较高的发芽率及发芽势。用15%PEG6000溶液模拟干旱胁迫环境,以浓度为150 mg/L壳聚糖处理PEG6000干旱胁迫下的玉米种子,研究表明,壳聚糖对提高种子的发芽率及发芽势具有极显著的效果,同时能极显著提高干旱胁迫下的玉米幼苗的根系活力。

Effects of Chitosan on Germination of Seeds and Drought Tolerance in Maize

Maize seeds were soaked in different concentration solutions of chitosan. The results showed that seed germination rate and seed germination potential was the highest using 150 mg/L chitosan. The maize seeds were treated with 150 mg/L chitosan under drought stress supplemented with 15% PEG₆₀₀₀ solution. Chitosan could increase significantly the seed germination rate, seed germination potential and the root activity of maize seedlings as well.
