How Do Pomegranates Spread Their Seeds? A Detailed Explanation of Pomegranate Seed Dispersal Methods

The pomegranate is a juicy, seedy fruit that is loved by many people for its rich content of various nutrients and its sweet taste, so how do pomegranates spread their seeds?

1. Growth habits of the pomegranate

The pomegranate is a deciduous tree or shrub of the family Lythraceae and the genus Punica. Its tree height is generally 3-4 m, and at most it can grow to 7 m. The pomegranate is very rich in nutrients, and its vitamin C content is 1-2 times higher than that of fruits such as apples and pears.

The pomegranate prefers a warm, sunny environment and is not strict about the soil in which it is planted, but it grows better when cultivated in well-drained sandy loam.

2. How do pomegranates spread their seeds?

Pomegranates mainly spread through themselves and through animals. After the pomegranate ripens, it splits open, and the seeds inside fall to the ground, where they will germinate and grow under suitable conditions. Birds and other animals also eat pomegranates, and the undigested pomegranate seeds are excreted with the animals' droppings, allowing them to grow in other places.

3. Propagation methods of the pomegranate

1. Layering

Before budding, take a relatively large sucker from the base of the mother tree, girdle it at the base to create a wound and encourage rooting, then mound soil 8 cm to 10 cm high; after autumn, the rooted plant can be severed from the mother plant to form a new seedling.

2. Cuttings

Cuttings are further divided into long-branch cuttings and short-branch cuttings, among which:

Long-branch cuttings are mostly used for directly establishing an orchard or for small-scale propagation in a courtyard. The specific method is to dig a planting pit 60 cm-70 cm in diameter and 50 cm-60 cm deep at the planting site, then insert 2-3 cuttings in each pit, with the angle between the cuttings and the ground at 50°-60°, then fill in soil while firming it down, and finally irrigate and build a tree basin, covering with plastic film or grass to preserve moisture.

For short-branch cuttings, before budding, cut disease-free and pest-free one- or two-year-old branches from a vigorous mother tree as stock shoots, cut the stock shoots into short cuttings with 2 to 3 nodes, and after cutting, soak them in a 5% 300-fold solution of junduqing for 10-15 seconds for sterilization treatment, then soak the lower ends of the cuttings in a rooting powder aqueous solution for 5 seconds, or in a 0.05% indoleacetic acid solution for 2 seconds, or in a 0.05% naphthaleneacetic acid solution for 3 seconds before cutting. At a row spacing of 30 cm × 12 cm, insert the cuttings into the soil with the slanted side facing down, with the upper bud eye 1 cm to 2 cm from the ground.
