To test effects of fertilization on late-season growth and nutrient content of container-grown red pine (Pinus resinosa Ait.), seedlings were subjected to a factorial combination of two fertilization regimes (exponentially increasing concentrations providing 25 (1N) and 75 (3N) mg N seedling(-1), respectively) and two irrigation regimes (well-watered and water-stressed) followed by drought-hardening or nonhardening. The fertilization treatments gave rise to steady-state nutrition in the…

Biomass and nutrient dynamics of Chinese fir seedlings under conventional and exponential fertilization regimes

Steady-state nutrition and superior growth performance were achieved by seedlings fertilized exponentially at the operational dose, and high dose exponential fertilization induced steady state-nutrition late in the season, demonstrating effective nutrient loading of plants without changing biomass.

Distinct Growth and Nutrient Status Responses to Fertilization Regimes in Two Generations of Chinese Fir Seedlings

It is suggested that exponential fertilization can improve the nutritional status, survival, and growth of Chinese fir seedlings, especially on competitive sites, and that information on both intra-species genetic variability and appropriate fertilizer levels is necessary for the successful fertilization of Chinese Fir seedlings , regardless of fertilization levels.

Nutrient dynamics and carbon partitioning in nutrient loaded Picea mariana [Mill.] B.S.P. Seedlings during Hardening

Biomass and nutrient dynamics of black spruce seedlings during the hardening phase of the greenhouse rotation were examined after four pre‐hardening fertilization regimes to assess nutrient dilution and steady‐state nutrition.

Root growth characteristics, biomass and nutrient dynamics of seedlings of two larch species raised under different fertilization regimes

The effects of different fertilization regimes on root growth characteristics, nutrient uptake and biomass production of Japanese larch (Larix kampferi Sarg.) and its hybrid larch (L. gmelinii × L.

Substrates and nutrient addition rates affect morphology and physiology of Pinus leiophylla seedlings in the nursery stage

The results indicate that ER is likely to give rise to more suited seedlings for outplanting in low fertility sites than CR, and suggests that K limited the growth of seedlings in sawdust, likely due to the low capacity of this substrate to adsorb K.

Growth and nutrient dynamics of western hemlock with conventional or exponential greenhouse fertilization and planting in different fertility conditions

The influence of postplanting fertility, both in the nursery and in the field, outweighed the effect of greenhouse exponential nutrient application and the capacity for nutrient loading in container-grown western hemlock was likely exceeded.

Combined pre-hardening and fall fertilization facilitates N storage and field performance of Pinus tabulaeformis seedlings

The results indicate that pre-hardening fertilization is a useful tool to nutrient load Chinese pine in the nursery and facilitate outplanting performance in the field, although further research is needed to precisely match rates of pre- hardening and fall fertilization to optimize seedling performance.

Growth and nutrient dynamics of transplanted Quercus variabilis seedlings as influenced by pre-hardening and fall fertilization

Stored nutrient reserves are closely correlated with survival and growth of transplanted seedlings. Previous studies have proven that combining pre-hardening fertilization (PF) with fall

Hardening fertilization and nutrient loading of conifer seedlings

Continuing to fertilize bareroot and container seedlings during the hardening process (from cessation of height growth until lifting) can improve seedling viability and lead to luxury consumption indicated by foliar nitrogen (N) concentrations > 2.5%.

Steady-state nutrient preconditioning and early outplanting performance of containerized black spruce seedlings

First-season height growth and shoot biomass of trees outplanted on different surface soils in pot bioassays were significantly improved by steady-state nutrient preconditioning and were accompanied by increased plant nutrient uptake, particularly N at the half-dos.

Carbon and nitrogen allocation patterns of Douglas-fir seedlings fertilized with nitrogen in autumn. II. Field performance

Fertilized seedlings broke bud 9–10 days earlier, produced more shoot growth, and, as shown in later harvests, had higher relative growth rates than unfertilization seedlings, however, initial differences in growth response were due primarily to the earlier budbreak.

Growth and nutrition of containerized Pinusresinosa at exponentially increasing nutrient additions

Containerized red pine seedlings were reared on different fertility regimes that compared conventional applications of a recommended 39 mg N per seedling as a complete nutrient solution with more frequent applications of an equal, one-half, or one-quarter amount of nutrients delivered at exponentially increasing solution concentrations over the same time period, indicating that superior seedlings can be grown successfully at low concentrations of nutrient solution.

A 5N × 5P factorial fertilizer experiment was conducted on Douglas-fir seed beds at Campbell River nursery on northern Vancouver Island and survival and height 2 years after planting out were significantly affected by N fertilizer treatment, but not by P fertilizer.

Diagnosing Nutritional Status of Containerized Tree Seedlings: Comparative Plant Analyses

D diagnosis by vector analysis agreed closely with actual growth and nutritional responses to treatments, and was more precise than the other approaches, and improved identification of dilution effects and nutrient interactions which tend to complicate conventional diagnostic techniques.

In a species such as red pine, with determinate height growth, environment during bud formation played an important role in determining later shoot responses by acting on the bud size.

Theory and techniques for steady state mineral nutrition and growth of plants

High accuracy in the control of nutrition and growth has been obtained in solution culture experiments in which the relative addition rate was applied as the treatment variable, when all necessary nutrients were accounted for, when the additions were made very often, and when the culture solution was in darkness and in good physical contact with the roots.

Genetic diversity in red pine: evidence for low genic heterozygosity

It is concluded that red pine is genetically depauperate and was at sometime, possibly during the Pleistocene, reduced to a small refugial population and has yet to reestablish equilibrium heterozygosity.
