Technical Services Division: Seedling Stock Quality Assessment

Seedling Stock Quality Assessment

The Seedling Testing and Tree Improvement Lab at KBM Forestry Consultants began in 1998. From modest beginnings, it has slowly expanded in response to client demand.

Seedling Testing Service
Provides third party, impartial testing for seedling growers and company foresters. Services include:
  • Shoot Frost Hardiness Testing
  • Stock Quality Assessments
  • Primordia Counts
  • Crop Monitoring and
  • Growth Progression

As well, there are two new tests in development: Root Electrolyte Leakage (to detect problems with the root systems before packaging) and Root Frost Hardiness (to determine the readiness of roots for storage).

Shoot Frost Hardiness (and Primordia Counts)
  • Testing to determine the readiness of seedling shoots for cold storage. The extent of damage to seedling shoots in a controlled freezing test is measured. Base testing is conducted to –15C, but customized testing from 0C to –40C is available.
Stock Quality Assessment
  • This consists of Seedling Certification testing and Problem Stock testing. Seedling Certification confirms the suitability of stock for planting, whereas Problem Stock testing is performed when problems are suspected. Both types of testing are performed using test procedures, standards and database management provided by the Ministry of Natural Resources’ Ontario Forest Research Institute.
Customized Crop Monitoring
  • Crops are monitored for overall health, signs of pests/disease, and root development. Weekly or bi-weekly growth progressions are also available.

In addition, KBM’s Technical Services Division conducts the following tree improvement services for several clients in Northwestern Ontario:

Tree measurements and selections (including GPS information)

  • Cone, pollen and scion collections
  • Fertilization and GA injections
  • Pollen viability testing
  • Cross-pollination
