I currently have a thai hybrid caladium "Phayamol" with an inflorescence. My problem (as new to breeding caladiums) is that I dont know how long pollen is viable in the fridge/freezer.

Are they like colocasias/alocasias where the pollen is good when sealed airtight and chilled for around 3 months in ~33-40 degrees?

I have scoured the internet, and can find a lot of information verifying the 3 month rule on elephant ears, but nothing much for caladiums.

Any help/shared experience would be greatly appreciated, i have about 3-5 days until my inflorescence opens and pollen can be collected (given its not a sterile hybrid..which i will find out).

I got my caladium to bloom within 2-3 weeks by application of 450ppm GA3 foliar spray. Same for my Alo. watsoniana (which will also have its pollen collected for hybridization).

Thanks in advance, everyone,

... (Caladium hortulanum) makes it desirable to store pollen and to rapidly assess its viability for cross-pollinations in breeding programs. This study was conducted to develop a procedure to determine caladium pollen viability and to use that procedure to evaluate the effect of short-term storage conditions on pollen viability. The sucrose level in the culture medium was found to have a significant impact on the in vitro germination of caladium pollen; a concentration of 6.8% was determined to be optimal for pollen germination. Caladium pollen lost viability within one day under room (24°C) or freezing (-20°C) temperatures, but could be stored at 4°C for 2-4 days. ...
