Abstract

The reproductive potential of Coccinia grandis was studied in four experiments. (1) Establishment of C. grandis seeds from fruits taken from the wild (2) Fruit characterization and seed germination test (3) Seed drying using oven-drying (80⁰C) and silica gel in 1 and 2-week periods (4) Sprouting of stem cuttings with lengths (5, 10, 15, 20, and 25cm) and diameters (0.25, 0.5, 0.75, and 1.0 cm). A single plant produces 6 fruits a week each containing about 58 seeds with 74.6% seed germination. Germination takes 4 days. Method and duration of drying has no significant effect on seed germination but removal of 8-13% seed moisture reduces seed viability. Interaction between length and diameter of stem cuttings has also no significant effect on sprouting. Given its tolerance to drying, high fruit and seed yield, and ability of cuttings to sprout regardless of length and diameter, C. grandis has become a persistent and successful weed species in the country.
