    Notes: Summary Aqueous buffers were used to extract gibberellin-like substances from pea tissue. The method possesses several distinct advantages when compared with extraction methods using organic solvents. Aqueous buffer extracts can be prepared more rapidly and produce extracts which are free of pigments and other alcohol soluble materials. Extraction of pea with aqueous buffer has indicated the presence of two gibbrellin-like substances in addition to those previously described.

    Notes: Summary CCC was shown to be effective in retarding stem growth of sunflower; this effect was overcome by gibberellic-acid application. Using an agar-diffusion technique, the gibberellin (GA) content of sunflower apices treated with CCC was found to be significantly reduced as compared to controls. Similarly, the GA content of agar diffusates obtained from 2-day-old sunflower root tips treated with CCC was also significantly reduced as compared to controls. Root exudate or bleeding sap obtained from mature CCC treated sunflower plants contained no measurable GA-like substance, although it could not be argued that this was due to suppression of GA synthesis in the root systems.

    Notes: Summary A bioassay is described which is dependent upon the fact that gibberellin induced α-amylase release from barley half-seeds is proportional to the logarithm of gibberellin concentration applied. This bioassay has been successfully applied to the estimation of gibberellin-like substances in plant extracts. The bioassay has the following advantages: 1) Release of α-amylase is one step closer to the primary site of action of GA; 2) release of α-amylase is not affected by solvent residues and is apparently completely specific for gibberellin; 3) release of α-amylase is not affected by substances other than gibberellins present in crude plant extracts.
