中文摘要:为确定适宜蚕豆芽苗菜生产的浸种和光照时间,以小蚕豆品种‘监利’为材料,设置不同浸种时间(12、16、20、24和28 h)和光照时间(8、9、10、11和12 h/d),分析对蚕豆芽苗菜生长指标和营养指标的影响。结果显示:随浸种时间增加,蚕豆芽苗菜苗长、茎鲜重和可食率均增加;浸种16 h时,蚕豆芽苗菜的生长指标和可溶性蛋白含量均显著高于12 h;除16 h外,其他浸种时间的左旋多巴含量均显著<12 h。随光照时间延长,蚕豆芽苗菜的生长显著变慢,在光照时间为9 h/d时,左旋多巴含量显著高于8 h/d,且与其他处理并无显著差异;可溶性蛋白和可溶性糖均在9 h/d光照时间时达到最优含量。以左旋多巴含量为主要指标,兼顾营养和生长指标,蚕豆芽苗菜生产的最适浸种和光照时间为浸种时间16 h,光照时间9 h/d。

Effect of soaking and illumination time on the growth and quality of fava bean sprouts
Abstract:To determine suitable soaking and illumination time for the production of fava bean sprouts,the influence of different soaking time (12,16,20,24,28 h) and illumination time (8,9,10,11,12 h/d) on the growth and quality of fava bean sprouts were analyzed in this study.The results showed that the seedling length,stem fresh weight and edible rate of fava bean sprouts increased with the soaking time.After 16 h of seed soaking,the growth indexes and soluble protein content of fava bean sprouts were significantly higher than those of 12 h.Except for 16 h,L-DOPA content was significantly less than 12 h in all the other soaking time.With the extension of illumination time,the growth of fava bean sprouts slowed down significantly.When the illumination time was 9 h/d,the L-DOPA content was significantly higher than that of 8 h/d,and there was no significant difference with other treatments.Soluble protein and sugar reached the optimal content at 9 h/d illumination time.The L-DOPA content was taken as the main index,and both nutrition and growth indexes were taken into account.The optimum soaking time and illumination time for fava bean sprouts production were 16 h and 9 h/d,respectively.
