Controlled Release Fertilizer Improves Quality of Container Longleaf Pine Seedlings
In an operational trial, increasing the amount of nitrogen (N) applied to container longleaf pine seedlings by incorporating controlled release fertilizer (CRF) into the media improved seedling growth and quality. Compared with control seedlings that received 40 mg N, seedlings receiving 66 mg N through CRF supplemented with liquid fertilizer had needles that were 4 in (10 cm) longer as well as...
متن کاملSexual expression in container-grown jack pine seedlings.
We assessed the effects of nitrogen, drought and gibberellin A(4/7) on sexual expression of 2- and 3-year-old jack pine (Pinus banksiana L.) seedlings grown in either a 1/3 peat/sand mix or a 3/1 peat/perlite mix. The seedlings were either watered daily (well-watered treatment) or droughted by withholding water from July 13 to August 24 (drought treatment). Half of the plants in each irrigation...
متن کامل2008 Interim Guidelines for Growing Longleaf Pine Seedlings in Container Nurseries
Production of container longleaf pine (Pinus palustris Mill.) seedlings for reforestation and restoration exceeds that of bare-root production, but information on container production techniques has been slow to develop. Because outplanting success requires quality seedlings, interim guidelines were proposed in 2002 to assist nursery managers and tree planters in developing and using the best s...
متن کاملInfluence of plant-parasitic nematodes on longleaf pine seedlings.
Seedlings of longleaf pine (Pinus palustris) were grown in 20-cm pots for 5 to 7 months in the greenhouse following inoculation with a high or low level of one of seven species of plant-parasitic nematodes. Belonolaimus longicaudatus and Helicotylenchus dihystera had no effect on seedling growth. High inoculum densities of Hoplolaimus galeatus and Tylenchorhynchus claytoni caused a significant ...
متن کاملEffects of Crown Scorch on Longleaf Pine Fine Roots’
Photosynthate production is reduced by foliage loss. Thus, scorch-induced decreases in the leaf area of longleaf pine (Pinus pa/u&is Mill.) may reduce photosynthate allocation to roots. In this investigation the root carbohydrate concentrations and dynamics of longleaf pine after two intensities of prescribed burning were monitored. In September 1996,65-year-old longleaf pine were burned. Plots...
