Influence of GA3 and 4-PU-30 on leaf protein composition, photosynthetic activity, and growth of maize seedlings

The effects of gibberellic acid (GA3) and N1-(2-chloro-4-pyridyl)-N2 phenylurea (4-PU-30) on maize seedling growth, photosynthetic parameters, and leaf protein composition were investigated. Chlorophyll and total nitrogen contents in leaves increased simultaneously. Sodium dodecyl sulfate polyacryla...

Zusammenfassung:	The effects of gibberellic acid (GA3) and N1-(2-chloro-4-pyridyl)-N2 phenylurea (4-PU-30) on maize seedling growth, photosynthetic parameters, and leaf protein composition were investigated. Chlorophyll and total nitrogen contents in leaves increased simultaneously. Sodium dodecyl sulfate polyacrylamide gel electrophoresis of soluble proteins (albumins and globulins) revealed quantitative differences between 4-PU-30-treated plants and the other experimental variants. They differed in polypeptide composition associated with changes in soluble proteins and amino acids.
