Bioassay of gibberellic acid
WebGibberellic acid (10 muM) causes lettuce hypocotyl cells to elongate by 400-500% more than water controls in 72 hr. Kinetic data indicate that whereas in water controls cell elongation occurs between 24 and 48 hr, in gibberellic-acid-treated material it starts at 8 hr and continues to 72 hr. Dry weight of the cell wall shows a corresponding increase with … WebGibberellic acid (GA3) is the main product of gibberellins in fungi and bacteria (Bruckner and Blecschmidt, 1991) [7]. It is a terpenoid hormone that is an important phytohormone regulating ... Bioassay of gibberellins was done by α- amylase release test (Lindow et al., 1998) [20].
