Moisture: Effects of Water Stress on Trees,indirectly by limiting carbon gain. Water availability can also alter the allocation of carbohydrates between the root and shoot. Trees resist excessive rates of water loss through stomatal regulation, a process which may be mediated by the level of growth regulators transported from the roots durin

Nutrients: Use of Forest Fertilization and Nutrient Efficient Genotypes to Manage Nutrient Stress imits forest productivity. Much of the increase in stemwood growth following fertilizer additions is attributable to increased foliage production. Other mechanisms which may contribute to accelerated stem growth include increased productivity per unit of leaf area and altered dry matter partitioning

Low Temperature: Physical Aspects of Freezing in Woody Plant Xylem,. The first is a tolerance of extracellular ice formation and its associated dehydration while the second is avoidance of freezing altogether by supercooling. Extracellular freezing may be tolerated to experimental temperatures below −196°C in the most hardy species while supercooling is limited by

Multiple Stress Factors: The Potential Role of System Models in Assessing the Impact of Multiple St explore the effects of multiple climatic stresses on potential site productivity is presented as an example of systems modeling applied to stress management research. Predictions from this model are used to examine the effect of multiple versus single climatic stresses on seasonal stand productivit

Herbicide Stress: Use of Biotechnology to Confer Herbicide Resistance to Selected Woody Plants,wever, many herbicides damage the crop trees unless precisely applied. As a consequence, suboptimum weed control is often accepted in current silvicultural practice. Herbicide selectivity for weeds versus crop can be achieved in three ways; avoidance, tolerance, and resistance. Broad spectrum herbic
