Commercial for Asian flower contest (10)
I believe the answer is:
industrial
'commercial' is the definition.
(thesaurus)
'asian flower contest' is the wordplay.
I cannot quite see how this works, but
'flower' could be 'indus' (Indus River is an example) and 'indus' is present in the answer.
The remaining letters 'trial' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'for' is the link.
(Other definitions for industrial that I've seen before include "Rapid social changes, starting in Britain from about 1760" , "Involved in manufacture" , "plants may be so described" , "Like manufacturing" , "Type of action" .)
