The 2-Pyridinecarboxylic acid (2-PCA) acts as an inhibitor of ethylene biosynthesis in Arabidopsis thaliana by binding to the active site of 1-aminocyclopropane-1-carboxylate oxidase. In this study, we examined the action of 2-PCA in comparison with the action of 3-PCA, a recently discovered stimulator of flower opening, in cut flowers of the spray-type carnation cultivars, ‘Light Pink Barbara (LPB)’, ‘Carnet’, ‘Collin’, and ‘Zulia’. With ‘LPB’ flowers, 2-PCA at 0.5-5 mM did not prolong the vase life, whereas 3-PCA at 5 mM did so. With the other three cultivars, 3-PCA generally promoted flower opening of all the cultivars. On the other hand, the action of 2-PCA on flower opening and senescence varied with the carnation cultivar and time of harvest, resulting in a shortened, unchanged or lengthened vase life of the flowers. 2-PCA also caused severe bending of flower stems in all cultivars, which lowered the display value of the flowers. The present results showed that 2-PCA is not likely to be a useful flower care agent in carnation flowers. The experimental part of the paper was very detailed, including the reaction process of Picolinic acid(cas: 98-98-6Category: pyridine-derivatives)
Picolinic acid(cas: 98-98-6) is used as a chelate for alkaline earth metals. Used to prepare picolinato ligated transition metal complexes. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.Category: pyridine-derivatives
