Spinach seeds before sowing

Botanically speaking, the spinach seed is actually its fruit. After the ovules are fertilized, the cells become hardened and become the outer shell of the whole fruit. Some varieties have 1 to 6 protrusions on the cell sheet, which are called thorns. Therefore, spinach can be divided into spiny seed spinach and round seed spinach depending on the fruit shape. The spiny seed spinach seeds generally have a water chestnut shape, and the round seed spinach seeds have a round, oval or elliptical shape. Because spinach seeds are thick and hard, they are not easily permeable to water, so they germinate slowly. If the seeds are soaked before sowing, the pericarp of the seeds can be smashed to facilitate the quick water absorption and air permeability after sowing, which will facilitate emergence.
