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 ...

Selective feeding by herbivores on establishing seedlings has been suggested to affect genotype frequencies in several plant populations. The existence of genotypes susceptible to herbivores calls for an explanation in such populations. In the present study we assessed the choice of multiple herbivores, field voles (Microtus agrestis) and insects ...

The role of nutrients for improving seedling quality in drylands
New Forests, 2013Forest plantations have been extensively used to combat desertification. In drylands, harsh climate conditions and unfertile soils often preclude seedling establishment. The improvement in seedling quality by manipulating nutrient availability could contribute to increase planting success.

[Assessing indices of container seedling quality].
Ying yong sheng tai xue bao = The journal of applied ecology, 2002In this paper, the assessing indices of container seedlings quality were synthesized in accordance with growth and physiological factors. The results showed that the seedling quality might be determined by the dormancy state of terminal bud, nutrient condition of plant, and the state of root system.

Machine vision for conifer seedling quality control
New Forests, 1997A PC-based line-scan machine vision system providing rapid measurement of bare-root seedling morphological features has been developed. Designed for quality control and morphological data acquisition by nursery personnel, the machine provides a user-friendly, menu-driven graphical interface.

Nursery Cultural Practices: Impacts on Seedling Quality
1984Better understanding and implementation of nurserycultural practices to improve seedling quality will enable better matching of seedlings to forest sites, reducing the chance of regeneration delay and improving future growth of forest stands. This chapter reviews a number of important cultural practices and the ways in which they affect indicators of ...
