I'm a reporter working with an author on a book that will give readers a glimpse at the foods of the future, from test-kitchens to biotechnology labs. In short, the book looks at people, ideas, trends and technologies that could change what we eat in 25 years.  We are looking for information about produce respiration rates — I've come across several introductory papers, but I just need a data table comparing respiration rates for different fruits and vegetables. Is there any table with this information?  (C.B.)
