Vegetable whose production is determined by pollinator and temperature (4)
I believe the answer is:
beet
'vegetable' is the definition.
(I know that beet is a type of vegetable)
'pollinator and temperature' is the wordplay.
'pollinator' becomes 'bee' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'temperature' becomes 't' (abbreviation).
'bee'+'t'='BEET'
'whose production is determined by' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for beet that I've seen before include "Crop plant, sugar source" , "An edible root plant" , "Genus of plant with succulent root" , "Root, maybe source of sugar" , "E.g. chard, mangelwurzel" .)
