PURPOSE:To obtain the subject composition by combining a compound such as a lodging reducing agent or a flowering regulation agent exhibiting plant growth regulating action by foliar treatment with sodium 2,3:4,6-di-O- isopropylidene-alpha-L-xylo-2-hexurofuranosonate. CONSTITUTION:The objective plant-growth regulating composition contains a compound of formula I [A is H or methyl; R is hydroxyl, 1-6C alkoxy, alkoxyalkoxy, mono- or dialkylamino or -O-Cat (Cat is organic or inorganic cation)] (e.g. the compound of formula II) and sodium 2,3:4,6-di-O- isopropylidene-alpha-L-xylo-2-hexurofuranosonate. A synergistic effect can be attained by the combination of the above two kinds of compounds. Furthermore, the composition is effective in eliminating dark green discoloration and yellowish white discoloration of a plant to give a plant having appearance similar to the untreated plant. This is an important factor on an ornamental plant. |
