Paper, 'The influence of auximones on the growth of Lemna minor [common duckweed]' by William B Bottomley

Description

Bottomley writes: 'In a previous communication experiments were described which indicated what when peat is incubated with a mixed culture of aerobic soil organisms for about fourteen days at a temperature of 26°C., a rapid decomposition of the organic matter takes place, with the formation in the "bacterised" peat of certain organic growth-promoting substances or "auximones", the addition of which in very small amounts to wheat seedlings growing in water culture causes a marked increase in growth. It was desirable to repeat these experiments with plants in which any variation in growth could be readily and more accurately estimated than in wheat seedlings.'

Annotations in ink throughout. Includes ten microphotographs of plant cells and three graphs relating to rate of multiplication and variation in total area of plants.
