The initiation of Scots pine male flower primordia is connected with a high content of gibberellins and a low level of auxins, whereas the initiation of female flower primordia is correlated with a high content of auxins and a low level of gibberellins. There is lack of direct correlation between the content of cytokinins or abscisic acid and flower sex differentation
