Obligatory Parthenocarpy
B.
Vegetative parthenocarpy
C.
Facultative parthenocarpy
D.
Stimulative Parthenocarpy
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Seedless in Black Corianth grapes is due to Stimulative Parthenocarpy.The stimulative type of parthenocarpy occurs when pollination occurs but fertilization doesn't. It occurs by the insertion of the ovipositor of a wasp into the ovary of a flower.
In the Black Corinth variety of grapes, pollination and fertilization take place but the embryo gets aborted subsequently resulting in seedlessness.
