Information about saplings and seedlings of trees and shrubs
What are saplings?
Saplings are young trees. They can be produced in various ways:
Through seed
Vegetatively through cuttings
Growing saplings by seed
In general, seed produces plants that are variable in genotype and phenotype:
Genotype is the genetic capacity and characteristics of the plant
Phenotype is the visible characteristics of the plant
In short, we can say that variable populations of plants differ externally in how they look and differ in their capacities - like growth, resistance, fruit production, etc. Populations grown from seed are far more resistant to diseases for two reasons:
Through multiplication by seed, the plants are by nature, virus-free
In a variable population, plants have variable capacities to protect themselves against diseases. If a disease attacks a population originated from seed, one plant may die while another survives as it is less sensitive or not susceptible to that disease
Growing saplings by vegetative multiplication
Multiplication from one plant to a population of many. This can be done through the traditional way of cutting and re-rooting, or through tissue (vitro) culture multiplication. With these methods, all plants have the same genotype and phenotype. Through selection of the mother plant we can choose a plant that has extra capacities like more production, stronger growth, etc. But they are also very vulnerable to diseases to which they have no resistance. Once attacked, the whole population can and often will die.
Vegetative multipliction from a variable population of plants. With this method, the population is more variable than one created by vegetative multiplication from one plant; so it is less sensitive to an attack from disease. The advantage of this method is that we can focus on multiplying mother plants that carry better characteristics than a population that is multiplied through seed. Vegetative multiplication can be done through roots, stems or (small) parts of
