Pollen germination on the surface of 0.70% agar in water for 12 hours at 20-22C.<br>
The germination of pollen could vary between the flowers age and condition.<br>
All results must be copied 2-3 times. Since pollen may lose its capacity to germinate<br> 
by rain, dryness, heat, age, and poorly developed flowers ...<br>
When I collected pollen, I tried to take it from the newly opened anthers<br>
In polyploid plant the cells could have different numbers of chromosomes (sport) mosaics<br>
so sometimes the pollen can germinate (make pollen tubes) from some flowers.
