The Absorption and Translocation Of 2,4-Dichlorophenoxyacetic Acid by Bean Plants

The Absorption and Translocation Of 2,4-Dichlorophenoxyacetic Acid by Bean Plants.

The compound 2,4-dichlorophenoxyacetic acid (2,4-D) and similar compounds applied locally to aerial parts of plantsmay cause responses in plant parts distant from the place of treatment. Such responses have been used by several investigators as a measure of the translocation of 2,4-D. These studies have produced an important body of evidence on growth-regulator translocation. It has been report...

ABSORPTION AND TRANSLOCATION OF 2 , 4 - DICHLOROPHENOXYACETIC ACID AND p 32 BY LEAVES " 12

Foliar applications of nutrient minerals and the increasing use of systemic pesticides have served to reemphasize the importance of absorption and translocation in plant physiology. Studies of the movement of these materials have an immediate application value; at the same time they can aid in the solution of basic problems in plant behavior. A number of workers (5, 12, 14, 24, 30) have stresse...

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....

Effects of Temperature and Humidity on Foliar Absorption and Translocation of 2,4-Dichlorophenoxyacetic Acid and Benzoic Acid.

Little is known concerning the effect of humidity on the absorption of foliarly applied materials or their subsequent translocation. It is generally believed that the higher the humidity at any one temperature, the larger the amount of a foliarly applied material that penetrates the leaf per unit time. Most of the evidence for such an effect has been obtained indirectly. Koontz and Biddulph (16...
