2,4 Dichlorophenoxyacetic Acid

Sections of stems of Silene cucubalus, Galeopsis tetrahit, and Phaseolus vulgaris were cultured under sterile conditions in media containing inorganic salts, sucrose, agar, and the herbicides 2-methyl, 4-chlorophenoxyacetic acid, 2,4-dichlorophenoxyacetic acid, or 2-(2,4,5-trichlorophenoxy)propionic acid. The herbicide which gave the most effective control of a species under field conditions was also the most active in inducing root formation and proliferation on stem sections of that species. The response of the sections to these auxin herbicides diminished as the plants from which the sections were taken became more mature. The amount of herbicide recovered from treated shoots of these species was not correlated with susceptibility. It is postulated that susceptibility to these materials depends upon (i) the affinity of the species for the molecular configuration of the herbicide and (ii) the relative amount and functional importance of the susceptible tissues at the time of treatment.

2,4 Dichlorophenoxyacetic Acid

The uptake and subsequent distribution of 32P among the root, stem, and leaf tissues of bean seedlings growing in complete or phosphate-free nutrient and its incorporation into organic phosphorus fractions was studied. Plants growing in complete nutrient took up, retained, translocated, and incorporated less activity than those growing in phosphate-free solution. These results are discussed in relation to phosphate pools which appear to be present in bean seedlings. Fifty and 70 h after spraying with 5 p.p.m. 2,4-dichlorophenoxyacetic acid (2,4-D), no marked changes were observed in the uptake or distribution pattern of the 32P as compared to controls.
