Plant growth substances (plant hormones), a group of endogenous chemicals, are believed to play a pivotal role in plant development. The current view, exemplified by recent texts is that changes in development result from changes in growth substance concentrations; growth substances are the limiting factors in development. In contrast to this I think that growth substances are neither hormones nor limiting factors and that varuations in concentration do not control development; substantial evidence supports that view. It is sensitivity to growth substances (measured as capability to respond) which shows meaningful variations durings development and describes accurately what happens to devolopment in the intact plant. |
