Hi Peter,<br><br>Thank you for the quick answer. You mentioned Potter et al use Spjut's fruit terms in Rosaceae, do you have that reference? I found one article " A systematic Treatment of Fruit Types " by Richard Spjut from
<a href="http://www.worldbotanical.com/fruit_types.htm">http://www.worldbotanical.com/fruit_types.htm</a>, is this the guide we can follow? I will check our library to see if they have Spjut's book too. <br><br>Thank you again,

Oh dear, we venture into the swamp of rosaceous fruit terms! If we<br>are thinking of Rosaceae, the core of an apple is basically a fruit<br>proper, i.e. the post fertilisation products of the gynoecium. The<br>cortex is probably hypanthial tissue, mesocarp refers to tissues of a
<br>true fruit, i.e., it has little to do with what we eat in an apple<br>(but a great deal t do wit what we relish in raspberries or<br>blackberries (which of course are not berries) and flesh can refer to<br>anything fleshy irrespective of actual origin, including the flesh of
<br>a strawberry, which also is not a berry, but neither is it a "pome" -<br>the fruit of an apple, rather, it has a lot of achenes distributed<br>over the surface of an enlarged and fleshy receptacle. So the three
<br>terms that you mention are not interchangeable, and the third<br>(flesh) should not be usedin an ontology. The 'fruit skin peel' of<br>the GDR database has nothing to do with the fruit s. str., but is the<br>
epidermis and maybe a few adjacent cells of the hypanthium.<br><br>Note that in a recent paper Potter et al. use Spjut's fruit terms for<br>fruits of Rosaceae, for which you will need Spjut as a guide...<br><br>I hope this helps.
