Demeter was the goddess of the earth and the crops, and thus represented the fertility of summer and the autumn harvest; Persephone was the goddess of the new plants and the promise of spring. Persephone's abduction and Demeter's wandering were the winter, when the earth is cold and barren; Persephone's return was the return of the spring.
Also, it has been theorised that the myth is an explanation- or at least origin- of some of the stranger Greek marriage traditions (i.e., the ritual "abduction" of the bride by the groom.)
To explain the seasons.
It explained the seasons. After Hades stole persephone and made her his bride, he kept her in the underworld and in that time, Demeter was depressed so she gave the Greeks bad harvest, and with Persephone being in the underworld, no flowers could grow. This explained winter. During summer and spring, demeter and Persephone were re-united, so flowers bloomed on earth again, and the people's crops were revived.

Persephone was Demeter's daghter, so when hades kidnapped her, of course Demeter wanted her back. Eventually, the time Persephone spent with Demeter and the time with Hades was divided. When Persephone was with Hades, it was Winter. When she was with Demeter, it was Summer.
Persephone's parents are Zeus and Demeter.
Demeter adores Persephone because persephone is her daughter and the official start of spring

Demeter found Persephone with the help of Hecate and Helios.
Demeter and Persephone were both goddesses of the earth. Gaia (Earth) through her daughter Rhea, who was the mother of Demeter and grandmother of Persephone.
Demeter is Persephone's mother.
The Greek gods gave the ancient Greeks a way to explain things they didn't understand. For example, the ancient Greeks used the myth of Persephone and Hades to explain the seasons. When Persephone was with Hades in the Underworld, she was miserable. So her mother, Demeter (goddess of agriculture) , kept everything from growing, causing winter. When Persephone was with her mother, she was happy, and Demeter brought summer to the world.
