Faivre-duPaigre, Roger published the artcileMorphological modifications produced in Italian ryegrass by 2,4-dichlorophenoxyacetic acid (2,4-D), 2-methyl-4-chlorophenoxyacetic acid (MCPA), and 2-methyl-4-chlorophenoxybutyric acid (MCPB), Product Details of C12H16O3, the publication is Compt. rend. (1961), 3107-9, database is CAplus.
Application of 1, 2, 5, or 10 kg./hectare of 2,4-D, MCPA, or MCPB to Lolium italicum after tillering produces anomalous growth of stems and heads. Stems show aberrant tillering at the base of the plants and at internodes, and curvature of nodes and internodes. Rachises may be bi- or trifurcated, elongated or shortened, or have spiral or sinuate conformations. Spikelets may vary in point of attachment, may be pedicellate, compound, or sterile. A single plant may show any or all of these modifications.
Compt. rend. published new progress about 1798-04-5. 1798-04-5 belongs to catalysis-chemistry, auxiliary class Carboxylic acid,Benzene,Ether, name is 2-(4-(tert-Butyl)phenoxy)acetic acid, and the molecular formula is C12H16O3, Product Details of C12H16O3.
