✦ Synopsis

The effects of two synthetic auxins, BOA and BIA, on plant regeneration in vitro have been studied on explants of tomato cotyledons. The activity of these substances on cell elongation has also been tested on pea stem segments. It has been found that BOA is particularly effective in inducing the formation of shoots but has a weak activity on cell elongation, while BIA, which is more effective in inducing cell elongation, is less active in morphogenesis. It is concluded that (1) the two activities are not related to each other, (2) the receptors involved in the two processes are probably different, (3) the chemical structure of the auxin may be an important factor in organogenetic processes.

We tested the morphogenetic and cell elongating activity of 1,2-benzisoxazole-3-one, a compound similar to 1,2-benzisoxazole-3-acetic acid but lacking the lateral carbon chain. For comparison, we tested also the activity of indole 2,3-dione, having the same indolic ring as indole 3-acetic acid but n
