To provide theoretical evidence to aid adaptive management of bamboo plantation operating under the background of climate change,we studied the effects of simulated elevated atmospheric carbon dioxide (CO_2)and ozone(O_3)concentrations on mineral ion uptake and transportation in bamboo.We chose the biennial Oligostachyum lubricum as experiment material,and employed the open-top chambers(OTCs) test method in conjunction with a split-plot design to simulate the different atmospheric and elevated CO_2 and O_3 concentrations,Control[CK,(405)nmol·mol-1 O_3,(36020)mumol·mol-1 CO_2];elevated O_3 [EO,(10010)nmol·mol-1 O_3,(36020)mumol·mol-1 CO_2];elevated CO_2[EC,(405)nmol· mol-1 O_3,(70035)mumol·mol-1 CO_2]and combinations of elevated CO_2 and O_3[EOEC,(10010)nmol ·mol-1 O_3,(70035)mumol·mol-1 CO_2].Our results showed that,compared with CK treatment,EO treatment decreased significantly the Na~+ and Fe~((2+,3+))concentrations in O.lubricum,especially leaf and root,and the ions transportation ability among organs,while had no changes for the Ca~(2+)and Mg~(2+) concentrations. EC treatment had no changes in Fe~((2+,3+))and Ca~(2+)and Mg~(2+) concentrations with the exception of the decrease significant of Na+ concentration,but enhanced the Ca~(2+)and Mg~(2+) transportation ability from branch to leaf.EOEC treatment decreased significantly the Na+ concentration while increased the Fe~((2+,3+))and Ca~(2+)and Mg~(2+) concentrations and the transportation ability among organs.Based on these findings,we concluded that elevated ozone influenced the normal growth of O.lubricumby decreasing the concentrations of mineral nutrient and transportation ability among organs;elevated carbon dioxide benefited the growth of O.lubricumby enhanced the Ca~(2+)and Mg~(2+) transportation ability from other organs to leaf;the combinations of elevated ozone and carbon dioxide increased both the mineral nutrient concentrations and its transportation ability from other organs to leaf,and maintained the balance of mineral elements, and enhanced the adaptation capacity of O.lubricumto environments with higher ozone and carbon dioxide concentrations.
