Metabolites of 2,4-dichlorophenoxyacetic acid from bean stems

Metabolites of 2,4-dichlorophenoxyacetic acid from bean stems.

Changes in Chemical Composition of the Stems of Red Kidney Bean Plants Treated with 2, 4-dichlorophenoxyacetic Acid.

It has been shown (2, 5, 8, 11) that treatment of plants with 2, 4-D results in a reduction in carbohydrate content and an accumulation of nitrogen. Investigators (4, 6,) have reported that some plants sprayed with solutions of 2, 4-D develop enlarged and proliferated tissues, noted primarily in the stems. It has also been observed that some plants which were sprayed with 2, 4-D and which devel...

Modification of 2,4-dichlorophenoxyacetic Acid movement in bean petioles by light.

There have been several reports of light effe-cts on the movement of growth-regulating substances in plants. Shen-Miller and Gordon (6) found that phototropically active blue light decreased the basipetal movement of IAA in Zca coleoptile sections. Similarly, Thornton and Thimann (7) *observed that blue light induced a transient decrease in the basipetal movement of IAA in Avena coleoptile tiss...

Effect of 2,4-dichlorophenoxyacetic Acid on Proteolytic Activity of Red Kidney Bean Plants.

Recent work has slhown that treatment of plants with 2,4-dichlorophenoxyacetic acid (2,4-D) results in a reduction of carbohydrate and an accumulation of nitrogen (2, 10, 13, 14, 15). SELL et al. (14) and WELLER et al. (16) have observed differences in carbohydrate, nitrogen, and amino acid content that occur primarily in the proliferated stem tissue of the red kidney bean plants. LUECKE et al....

Influence of 2,4-Dichlorophenoxyacetic Acid on Pathways of Glucose Utilization in Bean Stem Tissues.

2,4-Dichlorophenoxyacetic acid (2,4-D) is the best known selective herbicide for effective control of broadleafed weeds in monocotyledonous crops. Although the mechanisms by which 2,4-D acts on plants have not been elucidated, several lines of investigation have shown: A. Stimulatory and inhibitory effects on the respiration of pea and oat tissues, depending upon the concentrations employed (6)...
