Chapter 19: How to Propagate Flowers
Flower reproduction is a means of multiplying flower offspring and preserving germplasm resources. Only when germplasm resources are preserved and reproduced in a certain amount can they be used for production and landscaping, and provide conditions for flower selection and breeding.Different species or varieties of flowers have their own different propagation methods and periods.Timely application of correct propagation methods to different kinds of flowers can not only increase the reproduction coefficient, but also make the seedlings grow robustly.

There are many methods of flower propagation, which can be divided into the following categories.

(1) Sexual reproduction is also called seed reproduction, which means that flower plants turn from the late vegetative growth stage to the reproductive stage, undergo flower bud differentiation and flower bud development, flower, and finally form seeds.The process of reproducing with seeds is called sexual reproduction.

(2) Vegetative propagation, also known as vegetative propagation, is a method of reproduction by using part of the vegetative body (roots, stems, leaves, buds) of flower plants to obtain new plants.Usually include meristem, cutting, grafting, layering and other methods.

(3) Spore reproduction Spores are directly produced by sporophytes of ferns, and they do not undergo sexual union, so they are essentially different from the formation of seeds.Ferns can be propagated by spores in addition to branching.

(4) Tissue culture is a method of inoculating plant cells, tissues or organs on a certain medium under sterile conditions to obtain new plants. Tissue culture is also called micropropagation.
