Reviewing my foldscope explorations on presence of different types of pollen in gourd, I plucked a flower from the same vine from which the previous flower was obtained. Teased an anther to dehisce its pollen and fixed them on a slide to view through the foldscope. The captured images showed the repeated results of dimorphic pollen. I prepared another slide of pollen in safranine stain which also confirmed the presence of dimorphic pollen.
One type of pollen which are ellipsoidal in shape and show presence of ridges.
Second type of pollen which is spherical and tricolpate
Presence of both type of pollen and pollen tube growth
Both the type of pollen clearly seen together and shapes clearly defined when stained with safranine.
