terms for fruit development stages

[Pankaj Jaiswal]

I am not an expert on this, but I presume Naama is trying to annotate 
her mutants suggesting the phenotype affects/observed_at this stage. Now 
the problem is this stage is also a process term in GO. Which is fine as 
long as we call it as a stage. We do have terms like these in plant part 
developmental stages like leaf development etc. that overlap with GO 
processes. In such cases we appended the term with a X-stage.
