| 摘 要： | 在光抑制条件下水稻不同品种的光合CO_2交换能力和量子效率均降低与叶绿体的电子传递活力和光合酶RuBPc受到抑制有关。强光逆境对光系统Ⅱ的抑制重于对光系统Ⅰ的抑制。与光抑制敏感的品种相比,耐光抑制品种在强光下光系统Ⅱ有较高活力。 籼粳杂种稻的光抑制特性更象粳稻,在株型育种的基础上,利用籼粳配组培育具有耐光抑制特性的优良品种,是当前育种的重要途径之一。

| Abstract: | The sensitivity of different rice varieties was studied on the leaf, chloroplast and enzyme levels respectively. It was found that the decrease of the photosynthetic CO2 exchange rate and photosynthetic quantum yield in different rice varieties under photoinhibitory conditions was related to the inh |
