New! Optimised ColdNSure Norway spruce customer report

Even more insight in cold tolerance development!
Since its development in 2006, the ColdNSure test has been a safe and reliable method to determine the winter hardiness of forest tree seedlings. The hardiness stage is of crucial importance for determining the moment of lifting and transfer to cold or frozen storage. The ColdNSure test is based on measuring the activity of a set of carefully selected cold tolerance genes.

After years of extensive validation, NSure is happy to announce the ColdNSure customer report for Norway spruce (Picea abies) has been improved. Next to the original classification in specific cold tolerance stages (0-3), a NSure Index value will be provided (figure 1). Based on the outcome of the test, a NSure Index value will be generated ranging from 0-100. With help of the new NSure Index you will be able to monitor the level of cold tolerance of your batch(es) more precisely. A batch of spruce seedlings is considered cold storable when they have reached a NSure Index value of 65 or higher.

The NSure Index value is displayed behind each sample. Spruce seedlings are considered cold storable when they have reached a NSure Index value of 65 or higher. 

In case of sufficient interest, NSure will to develop a similar customer report with a NSure Index for Scots pine (Pinus sylvestris).
