In fact, commercial fruit growers may stimulate fruit development in unpollinated flowers by applying synthetic auxin to the flower. Whats the best way to rinse strawberry seeds? Strawberry plants are sedentary; therefore, they rely on other organisms to carry their seeds. Mix some vermiculite or other water-retaining substance in the bottom 0.15 m of soil to help hold moisture.

A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka floral tube), which is a structure where basal portions of the calyx, the corolla, and the stamens unite with the receptacle to form a cup-shaped tube.

Depending on how these parts interact to form the fruit, we can classify them into different fruit types. Fleshy fruits are usually dispersed by animal ingestion, Kew Research Fellow Dr Si-Chong Chen says.
