What do narratives of education among displaced peoples offer a global manifesto in curriculum theory? We take up four themes that appear consistently across

Physiology Research Made Forestation With Container-Grown Seedlings Successfulere. Ongoing research with great promise includes precise spacing of seedlings through sowing germinated seed, stress testing to determine planting stock quality, relating different growth aspects to each other to develop the best “balanced” seedling, and seeking growth control mechanisms at the cellular and biochemical levels.

The Influence of Species and Stocktype Selection on Stand Establishment: an Ecophysiological Perspecains poor for many situations..Physiological and morphological characteristics important for adequate seedling performance under various types of environmental stress are discussed with emphasis on harsh-site reforestation. A conceptual model for the selection of species and stocktypes best adapted to specific site conditions is also presented.

Growth Response and Physiology of Tree Seedlings as Affected by Weed Control woody or herbaceous or both types of competition. Only in recent years have researchers attempted to relate the effects of vegetation management to tree physiology. It appears that in most cases competition results in water being the limiting factor for tree survival and growth.

Interference Between Greenleaf Manzanita (,) and Ponderosa Pine (,)factors since spatial arrangement and total density are held constant and proportion between species is varied. After the first growing season shrubs dramatically inhibited tree growth. Soil moisture was found to be the limiting factor for maximum tree growth when ponderosa pine occurred in association with greenleaf manzanita.

Nutrition Management: A Physiological Basis for Yield Improvement the South, delayed fertilization often results in slow growth and seedling mortality. Large gains in early forest growth and survival will require successful vegetation control and the integration of the numerous biological and physical factors governing fertilization response.

New Forests from Better Seeds: The Role of Seed Physiologys of seed maturation have led to new collection and extraction technology which should increase seed yields. Computer analyses of test data allow extension of seed testing beyond simple germination percents to estimates of seed vigor, that elusive quality factor which enables a seed to survive and g

Manipulating Loblolly Pine (, L.) Seed Germination with Simulated Moisture and Temperature Stressn loblolly pine (Pinus taeda) seed strongly influence seedling yields. The impact of moisture and temperature on loblolly seed performance was investigated by germinating seed at temperatures cycling between optimal (21°C) and stressful (13°C or 35°C) or in the presence of osmotically simulated mois
