利用动态离子流检测技术，通过比较干旱作用下旱稻与水稻对K+和Ca2+离子的动态吸收规律，探讨无机离子对旱稻和水稻的抵御干旱胁迫的作用机理，有助于筛选抗旱水稻材料。结果显示，PEG处理条件下巴西旱稻对K+和Ca2+的吸收能力强于日本晴水稻，可能是由于巴西旱稻通过吸收无机离子作为渗透调节剂抵御干旱胁迫，因此具有较强的抗干旱能力。同时研究也说明，利用动态离子流检测技术比较不同材料的无机离子吸收能力，可以筛选抗旱水稻新品种。

Using the dynamic ion flux test technical,we compared dynamic ion absorption of upland rice and rice to K+ and Ca2+ under drought stress,and discussed how inorganic ion worked in upland rice and rice resisting drought stress,which may contribute to screening drought resistant rice. Results suggest that,brazil upland rice has stronger K+ and Ca2+ absorption than nipponbare rice under 10%PEG treatment,through which we proposed that the brazil upland rice absorpted inorganic ions as osmotic modifier to resist drought stress,and has stronger drought-resistant ability. This research illustrates that using dynamic ion flux test technical to compare different materials’inorganic ions absorption ability,we can screen new drought resistant rice species.
