Plant Propagation New plants are obtained through a process called propagation. Propagation is defined as the increase of plant species from one generation to the next. Plant propagation is both an art and a science. The science involves the knowledge of the parts of plants and how they work together to cause growth. The are is in knowing how and when to work with the plant parts to obtain the desired result.
Sexual propagation uses the seeds of plants.
Seeds are produced when the male and female gametes or tissues, unite within the flower. After a seed is sown and germination takes place, the new plant, or seedling begins to grow. This stage of vegetative or nonflowering growing is called the juvenile stage. As the plant increases in size through the formation and growth of millions of new cells, the length of the stem and the cross section of the plant both increase. Leaves, stems, and other plant parts develop in this stage.
