Abstract:

The water culture experiment is to study the mechanism of Arabis alpinal Var. parviflora Franch’s absorption in Lead and Zinc with a pharmacological approach. The findings show that after the 50μmol.L-1uncoupler DNP treatment 12 h, 24 h and 36 h, the concentration of lead of Arabis alpinal Var. parviflora Franch’s roots increases by 4.4 times, 7.1 times and 1.7 times compared with the control ones. Under the action of ATP inhibitors Na3VO4, the concentration decreases 0.64 times, 0.76 times and 0.69 times. However, after the 50 μmol/L uncoupler DNP treatment 12 h, 24 h and 36 h, the concentration of zinc of Arabis alpinal Var. parviflora Franch’s roots decreases by 8.8 times and 5.4 times. The action of ATP inhibitors Na3VO4 has no impact on the zinc absorption of Arabis alpinal Var. parviflora Franch. Under the potassium channel inhibitor TEA treatment, Arabis alpinal Var. parviflora Franch’s root absorption of lead was significantly restrained. The decreased range is between 0.51 and 0.82 times compared with the control ones with different treatments. After the Calcium channel inhibitor LaCl3 treatment, a decrease is in the range between 0.50 to 0.97 times. While Arabis alpinal Var. parviflora Franch’s root absorption of zinc decreases by 0.94 and 0.58 times in comparison with the controlled after the TEA treatment and by 6.6% times and 9.4% times after the LaCl3 treatment 24 h and 36 h. It can be concluded from the above analysis that energy metabolism and ion channels have a greater impact on Arabis alpinal Var. parviflora Franch’s root lead absorption than zinc absorption.
