Pointed gourd (dioecious) is propagated by Stem cutting.
Trichosanthes dioica, also known as a pointed gourd, is a vine plant in the family Cucurbitaceae, similar to cucumber and squash, though unlike those it is perennial. It is a dioecious vine plant with heart-shaped leaves and is grown on a trellis.
It is normally propagated through stem cuttings & root suckers. Its seeds are not used in planting due to poor germination & inability to determine the sex of plants before flowering.
