A boundary-layer model has been used to describe the movement of dissolved oxygen through a vegetation mat of Wolffia sp. or Lemna minor. In an environment where light and temperature are held constant, the reaeration rate of the water below the mat

Tissue culture techniques were used to study the factors surrounding tuber formation in the common potato. In some instances, an adequate sugar supply was accompanied by a rapid change from the vegetative to the tuberized condition. Cultures maintain
