| Summary: | and diurnal water potential, stomatal conductance and architecture, and physiological attributes such as predawn better than those from southeast Texas, albeit with both growing seasons. Survival for all trees exceeded 85% on Cherokee County, Texas, were established. Site I was planted conductance for plantlets was higher than for seedlings, daily from and early morning minimum in all trees, and was exploit more soil water. for all variables. Both sites were established as split- greater percentage than plantlets. Transpiration increased Growth of root collar diameter, height and leaf area growth, higher for plantlets at all measurement times. Plantlet Higher root/shoot biomass ratio with higher water stress in however stomatal conductance never ceased for either stock measured for growth and survival. Site II, planted with negligible differences. Predawn and diurnal water potential penetrate deep in the soil for a given root length and Plantlets grow a more dichotomous or fibrous root system, plantlets was explained by their root system architecture. plots. Data were collected through the 1994 and 1995 growing Relative performance of loblolly pine seedlings and in vitro root/shoot biomass ratio was higher than that of seedlings. seasons. Seedlings grew considerably more than plantlets in seedlings and plantlets from all four families, were observed Site I and 90% on Site II.
