The ColdNSure test helps decision-making in ornamental and forest tree nurseries operations

During the cultivation of forest tree seedlings and ornamentals, nurseries must make irreversible decisions which have a major impact on quality. Therefore, it is essential that nurseries have access to reliable methods that can help them through those crucial decision-making moments.

NSure has a freezing tolerance test, called the ColdNSure test, on the market for 1-2-year-old seedlings of Norway spruce (Picea abies), Scots pine (Pinus sylvestris) and Douglass fir (Pseudotsuga menziessii). This test is based on measuring the activity of a specific set of genes which are involved in the development of freezing tolerance. By using the test, nurseries can accurately monitor freezing tolerance and determine when a batch of seedlings is ready for frozen storage. In Scandinavia, the test is broadly used for over a decade, and the last few years NSure observed an increase in the market for the ColdNSure in North West Europe.
















A
 similar test that determines when plants are ready for cold storage is on the market for Hydrangea. For Viburnum opolus ‘Roseum’, a test is available that determines if dormancy has been released sufficiently after a period of cold weather.
