乙酰胆碱对板蓝根^(14)C-同化物运输的影响

THE EFFECT OF ACETYCHOLINE ON ^(14)C-ASSIMILATES TRANSLOCATION OF Isatis tinctoria L.

以板蓝根源 通道 库模式系统研究了乙酰胆碱对板蓝根14 C 同化物运输的影响 ,结果表明 :低浓度乙酰胆碱处理板蓝根韧皮部 ,板蓝根叶片向肉质根输出的14 C 同化物增多 ,尤其以0 0 1mmol L的处理效果最为明显 ;说明低浓度乙酰胆碱增强了通道的运输活性。

The effects of acetycholine on 14C-assimilates translocation are studied with source-channel-sink of Isatis tinctoria L.The experiments show that 0.01mmol/L treatments of acetycholine on the phloem, can improve the output of 14C-assimilates in leaves indicating that acetycholine enhances the activity of phloem transport.
