I was pollinating the Bulbo lobbii, as i was trying to place the pollens into the stigma opening i noted the sticky/jelly thing sticking on the wooden pick.
I have pollinated the bellinas and others but never notice such richness in stigmatic fluid in them. what have you noticed in the orchids you grow while pollinating ? Does the amount of fluid played a role in successful pollination?
I get this in most of my dendrobs-sometimes it is liquid, sometimes it is a sticky plate like object. It varies. It is just a means of pollen transport-the sticky plate/fluid will stick to the back of the pollinator, who will rub the pollinia onto the collumn of another orchid. Very fascinating indeed
The younger flower usually when you pollinate them will give you high rate of viable seeds as compare to the old flower, so the sticky part on the flower basically will hold the stamen firmly into this chamber and allow the pollination succeed within a few days. Young flower basically having clear colorless stigmatic fluids and the old one more like straw color.
Thank you Cathy, and thanks Jordan and Zainal for the explanation.
