Assessing Seedling Quality

  • Chapter
Book cover Forestry Nursery Manual: Production of Bareroot Seedlings

Part of the book series: Forestry Sciences ((FOSC,volume 11))

Abstract

Characteristics of planting stock which reflect quality (defined here as performance potential) are categorized as either “performance” attributes or “material” attributes. Performance attributes, such as root-growth potential, cold hardiness, and stress resistance, are assessed by subjecting whole seedlings to certain environmental regimes and evaluating their response. Because performance attributes are integrators of all or many seedling subsystems, they often correlate well with seedling performance potential; however, they tend to require laborious and time-consuming procedures. Material attributes, such as dormancy status, water relations, nutrition, and morphology, are assessed by measuring the attribute in question by any number of direct or indirect methods. Although material attributes are often more easily and rapidly measured than performance attributes, the former generally yield little definitive information on seedling quality unless values fall well outside of some established range. Of the Northwest nurseries responding to the OSU Nursery Survey, many reported using various methods to assess seedling conditions. However, most methods were used to indicate the desirability of carrying out certain cultural operations, such as irrigation or lifting, rather than to measure seedling quality itself.
