The following tannins, Chinese gallotannin, 1,2,3,4,6-pentagalloyl glucose, chebulinic acid, procyanidin dimers, and procyanidin trimers were tested and found to be antagonists of seven gibberellins (GAs). Each tannin inhibited the growth induced by any of the gibberellins GA(1), GA(3), GA(4), GA(7), GA(9), GA(13), and GA(14) in the dwarf pea assay. Endogenous growth was not affected. The highe...
This study was undertaken to elucidate the dominant endogenous gibberellins (GA) and the changes in their levels in germinating barley during malting. Also, a method for determining gibberellins in barley and malt by combined gas chromatography-mass spectrometry (GC-MS) was developed. Endogenous gibberellins in germinating Fuji Nijo I I and Betzes barley were sequentially extracted with ethanol...
The maize orange leafhopper Cicadulina bipunctata (Hemiptera: Cicadellidae) induces galls characterized by growth stunting and severe swelling of leaf veins on various plants of Poaceae. Previous studies revealed that galls are induced not on feeding site but on distant, newly extended leaves during the feeding, and strongly suggested that some chemicals injected by the leafhopper affect at the...
