E
Ouksiene word in die apikale meristeem van die stingelpunt vervaardig vanwaar dit
eweredig afbeweeg in die stingel.
B
Die eweredige verspreiding van ouksien veroorsaak dat al die ye van die stingel ewe veel
groei en daarom groei die stingel regop boontoe.
B
Ouksiene is sensitief vir lig en beweeg weg van skerp lig af.
B
Indien 'n stingel blootgestel word aan 'n eensydige ligprikkel, sal die ouksiene wegbeweeg
van daardie kant en na die donker kant toe beweeg.
*
'n Hoer konsentrasie ouksiene aan die donkerkant laat die selle aan daardie kant meer en
vinniger groei.
I
Die laer konsentrasie ouksiene aan die kant van die ligbron, laat die selle minder en
stadiger groei.
B
Oneweredige groei vind plaas en die stingel buig na die lig.
*
Stingels is dus positief fototropies.
