Abstract

Abstract does not appear. First page follows.

A few investigations have shown the influence of the reduction of chlorophyll-bearing tissue on the carbohydrate concentration, and on the yield of fruit, grain, or herbage following removal of the aerial growth. Because of the difficulty of observing closely the parts below ground, however, few detailed studies have been reported which show the effect of the removal of top growth on the development of the plant as a whole, including the roots. The extent to which root development may be correlated with yield, also, is little understood. Further knowledge of such correlations appears to afford both scientific and practical possibilities.

Grasses were used in the studies here reported. The experiment was designed to obtain information on the following points: (1) the effect of removal of tops on root growth; (2) the effect of removal of tops on the yield and on the regeneration of the aerial growth; (3) the growth rate and the yield of non-harvested (undisturbed) plants. Study on the last mentioned phase was essential as a means of comparison.

The difficulty of observing and measuring roots was overcome by growing the plants in a nutrient solution.
