In details, the strongest inhabitation to the shoot growth was observed when neutral soluble fractionates were supplied. The shoot biomass with neutral soluble fractionates added was decreased by 10.52% over the blank control, resulting in obvious increase of root: shoot ratio. It suggests that the root exudates would be self-poisonous. Besides, both acid and alkaline soluble fractionates exhibited the trend to increase the stem height and it is necessary to exploit the reasons.

There was a maximum value for D against pH, which depended on the Aliquat 336 concentration only, and the pH value responding to the maximum D was 4.0～4.3 and 3.7～4.2 for 25% Aliquat and 50% Aliquat system, respectively. Acetic acid was bonded to Aliquat 336 by both ion exchange and chemical association, and diluent affected their parameters obviously. The apparent constant of ion exchange, K 1, increased in diluent, especially in chloroform. The apparent constant of association, K 2, increased in chloroform also, decreased in n -octanol, and kerosene affected K 2 not apparently.
