Far-Red Light Reflection from Green Leaves and Effects on Phytochrome-Mediated Assimilate Partitioning under Field Conditions.

abstract：:The effect of initial oxygen concentration on the rate and extent of oxidation of the respiratory chain carriers of anaerobic mitochondria from mung bean (Phaseolus aureus) seedlings was examined. The substrate was succinate, with malonate added to give malonate to succinate ratios of 6 to 12, thereby minimizing the f...
