不同烫种条件对绿豆芽生长的影响

摘要

The effects of different scalding condition on growth of mungbean sprout were studied. The water absorption , germination rate and mass ratio of sprouts to mungbean were analyzed. The results showed that scalding condition improved the yield and quality of mungbean sprout and reduced roots-rotted phenomenon. However, the seed won' t germinate normally under the long time of high temperature scalding condition. The best scald seed time is 20 -30 minute and the best temperature is 55 ℃ , mungbean sprout germination rate is 100% , hypocotyl is 3. 39 cm long, mass ratio of sprouts to mungbean is more than 4. 81, and mungbean sprouts grow best.%研究了不同烫种条件对绿豆芽生长情况的影响.从吸水率、发芽率和芽豆质量比等方面进行了实验分析.结果表明:烫种处理可以提高豆芽产量和质量,并减少烂根现象.但长时间的高温烫种使种子不能正常萌发.最佳烫种条件为55℃烫种20～ 30 min,萌发率高可达到100％；下胚轴长为3.39 cm;芽豆质量比在4.81以上且豆芽生长情况最好.
