How Does Wild Grape Spread Its Seeds? A Full Explanation of Its Dispersal Methods

Wild grape is also called mountain grape. The fruit is 1-1.5 cm in diameter, and the flesh contains seeds. The seeds are obovate, slightly concave at the top, with a short beak at the base. So, how does wild grape spread its seeds?

1. How does wild grape spread its seeds?

Wild grape spreads its seeds through birds or small mammals. When ripe, wild grape is sweet, sour, and juicy, and birds and small mammals especially like it. After the fruit is eaten by birds or small mammals, the seeds, being difficult to digest, are excreted along with the animals' droppings, fall to the ground in a new place, and take root.

2. Where is wild grape produced?

Wild grape is produced in Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shandong, Anhui (Jinzhai), and Zhejiang (Fumu Mountain), China. It grows on hillsides, in valley forests, or in thickets, at an altitude of 200-2100 m. It is not strict about soil conditions, and it can grow well in many types of soil. However, well-drained soil with a deep soil layer is best, and it is drought-tolerant but afraid of waterlogging.

3. How is wild grape propagated by cuttings?

1. Cut one-year-old branches pruned in winter into 16-18 cm long cuttings, with one plump bud at the top. Cut the upper end of the cutting straight across, with the cut about 1 cm above the bud, and cut the lower end at a slant, forming a cutting with more than 2 nodes. Keep the topmost bud on the cutting and cut off the lower buds.

2. Take cuttings from late March to early April. First treat the cuttings with α-naphthaleneacetic acid at 150 mg/kg for 16-24 hours, keeping the temperature at 15-20°C; use an electric heating bed or a heated kang bed. Then insert the cuttings into the seedbed.

3. Keep the seedbed temperature between 28-30°C for 20 days after inserting the cuttings, ensure suitable temperature and humidity from 25-45 days after inserting the cuttings, and appropriately control water and temperature from 45-60 days after inserting the cuttings, so as to prepare for transplanting in the open field.
