【摘要】 研究了豌豆种子在萌发过程中超微弱发光的变化规律 ,结果表明种子的发光强度是一个不断增强的过程 .黑暗中萌发比在光照下萌发过程的发光强度高 ,前者 3d后增加很快 ,后者 4 d后增加变快 .幼苗根部的发光强度明显强于其它器官的发光强度 .在不同 2 ,4 - D浓度下萌发的豌豆种子 ,根系活力与2 ,4 - D浓度呈相关性 ;根系超微弱发光强度也是随 2 ,4 - D浓度增大而增强的过程 ,因此植物超微弱发光可能与生物的活力呈一定关系 .更多还原

【Abstract】 The ultraweak luminescence of garden pea (Pisum sativum L.) during germination has been measured. Our results show that the intensity of ultraweak luminescence increases continually during germination, and even faster when seeds germinate in the dark. The luminescence intensity of roots appears higher than that of other organs of seedlings. The root system viability has a positive correlation with the 2,4-D concentration in the culture medium. Meanwhile, the intensity of this light emission of roots rises as the concentration of 2,4-D increases.更多还原
