I want to know the answer to the following question:
Where are cytokinins produced?
All the background I'm provided with is that "It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.". Is that enough to answer the question?
Answer: no
