[OGD] Gavino Rotor's work still stands?

[K Barrett]

I asked a bit ago if Gavino Rotor's work still stood and found the following 
link to an abstract of his work: 
http://www.botany.org/ajb/00029122_di001489.html  Its way down the page, so 
you'll have to scroll.

The part I'm interested in is the last two sentences.
"No relation was established between the length of the pseudo-bulb or the 
stage of leaf development and flower bud initiation. Observations made 
indicate a relationship of flower bud initiation with day-length."

Rotor spends much more time in the article on the relationship between day 
length and bud initiation than this abstract leads us to believe.  Rotor 
refers to the tendency of labiata to make up a pseudobulb and wait for a 
proper annual cumulative amount of light to occur (he even provides dates at 
which the proper cumulative amounts have been received).  And that if the 
plant hasn't received that amount of light it will lay up until it has been 
received.

So.
Does this work still stand?  Has it been shot down by more recent work?
