Question

Name the part of gynoecium that determines the compatible nature of pollen grain.​

Answer 1

Answer:

Compatible nature of pollen grain is determined by the stigma of carpel/ pistil

Answer 2

The pistil has the ability to recognize, the pollen, whether it is of the right type (compatible)or of the wrong type (incompatible). If it is of the right type, the pistil accepts the pollen andpromotes post-pollination events that lead to fertilization. If the pollen is of wrong type, thepistil rejects the pollen.The ability of the pistil to recognize the pollen is followed by its acceptance or rejection. It isthe result of a continuous dialogue between pollen grain and the pistil mediated by chemicalcomponents of the pollen interacting with those of the pistils.
