Quality planting material production of three major timber trees in agroforestry: Seed and nursery techniques

Quality Planting Material (QPM) may be defined as "the production of uniform, healthy, disease-free planting material raised through seed or vegetative methods with an overall goal to raise the physiological and phytosanitary quality of the plant and make it available to stakeholders to increase productivity." Particularly for economically relevant timber species, quality plant material (QPM) from agroforestry species is necessary. To produce high-quality planting materials on a large scale, it is important to have a thorough understanding of seed and nursery processes.
