Phosphorus responses of C 3 and C 4 species

  author={Marilou Halsted and Jonathan Paul Lynch},
An hypothesis was formulated that phosphorus (P) partitioning in tissues of C4 leaves would permit C4 plants to resist P deficiency better than C3 plants. To test this hypothesis, 12 C3, C4, and C3-C4 intermediate species were grown at adequate, deficient, and severely deficient P supply in a solid-phase-buffered sand culture system to characterize photosynthetic and growth responses. Species differed considerably in response to P stress. The growth of C3 species was more sensitive to P supply… CONTINUE READING
