The emerson enhancement effect of photosynthesis in poplar leaves


, : The emerson enhancement effect of photosynthesis in poplar leaves. Fiziologiya Rastenii (Moscow) 29(5): 901-907

The enhancement effect and the action spectrum of the enhancement of photosynthesis was studied in poplar leaves within the visible light region. Maximal effect was observed by using additional light of 665 and 481 nm. The results are in agreement with previous data obtained with other objects. Photosynthetic rate was measured by polarography. Light diodes were used as far-red light sources (700 nm), and the additional short wavelength light was obtained with interference filters; the additional light was introduced to the reaction chamber by wavebeam guides.
