The Depressant Effect of Carbon Dioxide Upon Photosynthesis

“…This is in agreement with the results of other workers, though there the fall is much smaller than in the present experiments. The value of ag resembles the findings of Willstatter & Stoll (1918) that yellow leaves have smaller Qio's than green leaves. According to his schema Briggs has offered explanations for both these facts.…”

“…workers have found values of i •5-2-5 (Blackman & Matthaei, 1905;Willstatter & Stoll, 1918;Matthaei, 1905). Lundegardh (1924) alone appears to have values approaching the present ones-5-0 for Cucumus sativus, 5-6 for Solanum tuberosum and 6-4 for Solanum Lycopersicum, 5-15° C.…”

“…Willstatter & Stoll (1918) performed the great majority of their large range of experiments in air streams containing concentrations of 4-6 %, .and many modern workers have followed their methods.…”

Photosynthesis, Facts and Interpretations

“…Not only are the factb dewl'ihed in the prwediiig cbhaptcr in agreement with this theory but also the influence of intermittent light in decreasing the induction loss is explained (14). If thc surplus of peroxide molecules formed in the first flash is small it will be taken rare of by the catalyst in the following dark interval.…”

Photosynthesis Under Natural Conditions

“…They benefited especially from the kinetic foundations laid by Blackman and his school in earlier decades (e.g., 5), and by Willstatter & Stoll (257) in 1918. The unique value of aquatic plants, particularly unicellular algae, was less readily appreciated for illustrating photosynthetic processes in nature than for the laboratory work on the photosynthetic mechanism that followed the pioneer experi ments of Warburg.…”
