Basic Principles of Coniferous Tree Physiology and Morphology

The physiological and morphological characteristics of seedlings influence their survival and growth. The principles in this section represent the most current research findings available, along with the experience and knowledge of many experts. Physiological and environmental requirements vary by species and seed source, and even vary between different tissues of the same plant. The requirements discussed in this section are based on general experience, modified and supported by research, to fit standards suitable for production.

The principles of coniferous tree physiology and morphology presented in this section relate to handling and shipping procedures.

• Dormancy
• Temperature and Humidity Control
• Exposure to Light
• Exposure to Toxic Substances
• Mechanically Induced Damage
• Mycorrhizae
