8. Investigations on the Influence of certain Rays of the Solar Spectrum on Root-Absorption and on the Growth of Plants
Published online by Cambridge University Press: 15 September 2014
Extract
This paper details an investigation undertaken to see the influence of certain rays of white light on root-absorption and assimilation in the vegetable kingdom. One of us has been for some years investigating a problem as to the use of ferrous sulphate as a plant food (see Dr Griffiths' memoirs in Journal of Chemical Society [Trans.], 1883, 1884, 1885, 1886, 1887). In the experiments to be detailed here, we have used ferrous sulphate as an indicator of root-absorption.
