Abstract: Mineral ions are important to human bodies but only through food intake rather than in vivo synthesis.Saline-alkaline stress affects the absorption of mineral ions in rice.To meet the requirements of widely planting rice in saline-alkaline soil and breeding rice varieties with more mineral ions, we selected four rice varieties (Jinongda 511, Songjing 14, Longdao 11, Songjing 12) suitable for local climate to study the effects of saline-alkaline stress on K, Na, Ca, Mg, Fe, Mn and Zn uptakes in rice grains as well as the correlation between mineral elements.The results showed that the contents of the seven elements in the grains of four rice varieties was in an order of rice husk >brown rice > white rice, respectively.Compared with non-stress treatment, saline-alkaline stress significantly promoted the Na absorption of rice grains, and significantly enhanced the Na absorption of brown rice and white rice of "Longdao 11", respectively.The contents of K and Mg increased slightly but not significantly.The absorption of Ca, Fe, Mn and Zn was significantly decreased.Saline-alkaline stress significantly reduced the absorption of Ca and Mn by rice husk, but increased the absorption of Ca by brown rice.There was no significant difference in the content of Fe and Mn in brown rice and white rice with saline-alkaline stress.Saline-alkaline stress increased the absorption of Na and Ca in the white rice, while decreased the absorption of Fe, Mn and Zn.The correlations between mineral elements in rice grains were affected by saline-alkaline stress.There was a significant positive correlation between Zn and Ca in the white rice with non-stress;there was a significant positive correlation between Mg and Fe, while a significant negative correlation between Mg and Na in the white rice with saline-alkaline stress.
