EFFECT OF SOIL ETHYLENE ON PHOTOSYNTHESIS OF CITRUS TREES |
| Authors: | T. Ishii, K. Kadoya |
| Abstract:
When citrus roots (Satsuma mandarin trees on trifoliate orange rootstocks) were exposed to ethylene for a week, inhibition of photosynthesis was observed at 0.5 ppm and above ethylene, but not at 0.05 ppm. The rate of recovery of photosynthetic activity following treatment with 5 ppm ethylene was slow compared with that following treatment with 0% oxygen + 20% carbon dioxide. | |
