What will happen if pollen of rose gets deposited on stigma of lily flowers ? Will germination take place ? Why?

Dear Student,

Please find below the solution to the asked query:

Pollen grains are able to form a pollen tube only within their species. If pollen grain of one species is transferred to another species it will not germinate to form pollen tube. This is due to interspecific incompatibility which prevent the pollen from forming pollen tube if it belongs to different species altogether.

Hope this information will clear your doubts about the topic.
