Bioassay of gibberellins is carried out by
The correct option is B All of the above
Gibberellin is the plant hormone which is produced by the plastids to regulate the growth of plants. The identifying gibberellins are based on a common principle- a high response of the stem or its individual portions to this phytohormone. Michalski carried out extensive comparative work to investigate various gibberellin bioassay systems. He found most sensitive system was lettuce which responded to 10−10 g/ml of gibberellic acid. The response of the phytohormone is but one property of the bioassay. Michalski showed that the specialised property of gibberellins, namely its ability to affect an entire plant, disappears if only part of a plant is used for a bioassay. This regularity was observed on intact plants of rice, maize, pea, cucumber and lettuce.
