	VOLUME 3, TOPIC 12 SUMMARIES OF VOLUNTARY PAPERS FACTORS AFFECTING SURVIVAL AND EARLY GROWTH OF SEEDLINGS Ulvi Tolay1 Between lifting and planting, seedling roots are exposed and vulnerable to environmental stress, particularly temperature and moisture extremes. Moisture and root growth potentials most often limit seedling establishment once the site is prepared to provide enough moisture for growth. Nursery practice such as irrigation, fertilizing and varying the bed density, transplanting, undercutting, wrenching and proper handling are all used to manage seedling survival and early growth in plantations. Mortality or poor growth may be clearly due to a number of factors, in the nursery or as a result of handling practices, or site factors. The mechanical, meteorological, biological and other factors affecting the performance of the seedling certainly have physiological effects, no doubt often of a complex nature. While these may in time be elucidated by the use of controlled-climate laboratories, the final evaluation must always be the performance of the seedling in the forest. Keywords: Nursery, plantation, seedling growth, survival. 1Lecturer, A.I.B. University, Forestry Faculty, Düzce, Turkey.
