While there are certainly other considerations, such as fruit color, 

 size, maturity, and Ca concentration, it may be useful to include rootstock 

 when deciding which fruit are to be stored, particularly in CA. These sur- 

 veys suggest that fruit from seedling rootstocks trees have less post- 

 storage breakdown than fruit grown on W rootstocks, though no clue as to 

 the reason for this is seen.
