getting Zantedeschia hybrids to flower

Diane,
I was mistaken in my explanation of the BA treatment of Zantedeschia bulbs. In the research paper I cited, the bulbs were dipped 6 times during 3 months of storage. Sorry for the error.

Hi Diane,
it COULD be just the storage alone - I dig up my Zantedeschias every winter and store them dry in the basement - round about 9°C - and I've never had any trouble getting them to flower as long as they get adequate light in summer. I guess leaving them in the ground in BC in winter deprives them of the drought stress they get in winters in South-African summer rain climate. Maybe the GA3 s(t)imulates a natural process happening when the plant gets dry?

Thank you for the explanation, Mark.
So, the bulbs would need to be dug up every year in order to be treated. I wonder if the parental species are some that require fires before they bloom in the wild.
