为了弄清耐低钾水稻的生理学特性,笔者用14C、86Rb示踪研究了耐低钾能力不同品种在低钾条件下的光合作用、光合产物运输、光呼吸、暗呼吸及86Rb(K+)的吸收和长距离运输.发现这些生理指标与水稻耐低钾具有某些联系,现报道如下。 一、材料和方法 1.供试材料 发芽的水稻种子播于石 In order to understand the physiological characteristics of low-potassium tolerant rice, the authors studied the photosynthesis, photosynthetic transport, photorespiration, dark breathing and 86Rb (K +) of different varieties with low potassium tolerance under low potassium conditions by 14C, 86Rb tracing. Absorption and long-distance transport.It was found that these physiological indices have some connection with low potassium resistance in rice, and are reported as follows. First, materials and methods 1. Test materials Sprouted rice seeds sown in stone
