三种柑桔砧木对缺铁黄化的敏感性及机理研究

MECHANISM AND SUSCEPTIBILITY OF THREE ROOTSTOCKS OF CITRUS TO IRON CHLOROSIS

摩洛哥酸橙、构头橙和25号枳在缺铁条件下,根吸收区发生不同程度的适应性变化。三者根系分泌H^+和忍耐缺铁的能力依次为:摩洛哥酸橙>构头橙>25号枳。

The absorption areas of the roots among Morogo sour orange, Gouto sour orange and No. 25 trifoliata are different iron chlorosis conditions. The resistance to iron chlorosis and the capacity roots to secrete H—ion are: Morogo sour orange>Gouto sour orange>N. 25 trifoliata.
