For gene dispersal by seed formation to occur from a cut carnation flower, the following events would all need to occur successfully; arrival of viable pollen on the stigma of the carnation, pollen germination, pollen tube growth to the ovule of the carnation, fertilization, seed formation and seed dispersal. The seed can remain dormant until conditions are suitable for the embryo to begin growing. Ask your question.

Seed viability assessment before and after sowing (notes will be provided) It is important to find out if seeds put in nursery for germination remain viable or not. Seed formation begins with the combination of a male and female gamete: a process known as fertilization. Image Courtesy : tnmanning.com/5dda1590.png 1956b.

The most common forms of germination include a seed sprouting to form a seedling and the formation of a sporeling from a spore. The appearance of a viable seed requires the coordinate growth and development of the preceding three compartments. Seed development and germination.
