    Haiti has suffered great losses from deforestation, with little forest cover remaining today. Current reforestation efforts focus on seedling quantity rather than quality. This study examined limitations to the production of high-quality seedlings of the endemic Hispaniolan pine (Pinus occidentalis Swartz). Recognizing the importance of applying sustainable development principles to pine. The success of forest establishment program, including afforestation, reforestation, and forest restoration [1,2] mainly depends on the quality of Forest Reproductive Material (FRM), i.e., seedlings [3,4] and seeds [].FRM is often subjected to transfer and trade [6,7], emphasizing the genetic component of FRM quality regarding the seed source [] and genetic diversity of seed lot used for.

    Researchers of criminal behavior are taking a more data-driven approach to community corrections. Rather than focusing solely on professional experience or anecdotal successes — key factors that often drive public policy in social services — they are identifying evidence-based practices that rely on empirical research and produce measurable outcomes.   The Cincinnati Evaluation System. Jointly developed by the local teachers union and district more than a decade ago, the Cincinnati Public Schools’ Teacher Evaluation System (TES) is often cited as a rare example of a high-quality evaluation program based on classroom observations.

    weight fraction of shoots are measurements of seedling water status, and values often vary seasonally. REL is a measure of root membrane function; high values indicate that the plants are damaged or highly active. RGP is a measure of the seedling's ability to initiate roots in a . Limited prognostic and predictive ability of traditional morphological, immunophenotypic, and cytogenetic tests has driven research to define more subtle nucleotide-level alterations that not only shed light on pathogenesis but also serve as tumor markers and, in .

(Duryea, M. Ed.). Forest Research Laboratory, Oregon State University, Coryallis. Since the early 20th century, silviculturists have recognized the importance of planting seedlings with desirable attributes, and that these attributes are associated with successful seedling survival and growth after outplanting.

Over the ensuing century, concepts on what is meant by a quality seedling have evolved to the point that these assessments now provide value to both the nursery.

The concepts and principles in characterization of seedling performance potential are evaluated, the requirements of tests are discussed, and the guideline criteria presented in selected morphological and physiological tests are assessed.

Further discussion follows concerning the development of proper concepts as a necessity for developing clear and operational devices, and problems in making.
