Seeds, segments, and size

I wanted to share a little bit of my useless plant physiology with you guys
on this discussion about seeds and segment, and their affect on size.  

I learned in school that the cells in an enlarging fruit are allowed to
expand due to the acidification of their cell membrane by the plant growth
regulator auxin.  This hormone allows the membranes to be become pliable
and thus allowing the turgor pressure of the cell to push it outward- 
incidentally this is my explanation for why the fruit put on most of their
size during the night.   

The take home message here is that the hormone auxing is produced by the
developing seeds.  This is why complete pollination (ie...hand pollination)
 is so sucessful.  The more complete the pollination, the more seeds
produced, and the more auxin gernated, thus more fruit enlargment.  



Just a little food for thought, best of luck to everyone
