    Succulent plants such as the saguaro cactus have adaptations that include having no leaves, storing water and synthesize food in their expandable and fleshy tissue, and opening their pores only at night to take up carbon dioxide and reduce water loss.

    Al-toxicity is possibly of more importance to Norway spruce and silver fir than to other conifers (e.g. Scots pine, European larch, Sitka spruce, Douglas fir) (Eldhuset et al., , Schaedle et al., , Sverdrup and Warfvinge, ). Aluminium accumulates preferentially in the root tips where it can influence cell division and cell by: Plant growth depends on soil mineral elements, a lack of which results in reduced nutrient accumulation leading to poor growth and resistance in plants. Therefore, more information is needed about the response of Pistacia chinensis Bunge (P. chinensis) seedlings to nutrient deficiency. In this study, we investigated how soil nutrient availability affects the nutrient accumulation and root Author: Xiehai Song, Fangfang Wan, Xiaochao Chang, Jin Zhang, Minghui Sun, Yong Liu.

Sequoia sempervirens / s ɪ ˈ k ɔɪ. ə s ɛ m p ər ˈ v aɪ r ən z / is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae).Common names include coast redwood, coastal redwood and California redwood. It is an evergreen, long-lived, monoecious tree living 1,–1, years or more. This species includes the tallest living Family: Cupressaceae.

Tissue nutrient concentrations of Douglas fir and Sitka spruce in sand cultures, and value of nutrient concentration levels for in- terpreting foliar analysis. The influence of nitrogen, phosphorus, potassium and magnesium deficiencies on the growth and development of white spruce, black spruce, jack pine, and western hemlock seedlings grown in a controlled by: Highlights Nutrient concentrations (N, P, K, Ca, Mg, Na) in stumps and roots were assessed.

Nutrient concentrations were higher in birch stumps compared to spruce and pine. Nutrient concentrations were higher at southern sites, except for P. Concentrations were higher in the bark compared to the wood. Nutrient concentrations increased significantly with decreasing root by: Nutrient Content of Sitka Spruce Litterfall M.

Narrow-band spectral reflectance measurements in the visible and near-infrared region of the spectrum were investigated for the detection of nutrient deficiencies, and estimating the foliar concentrations of nitrogen, phosphorus, sulphur, and total chlorophyll.

One-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were treated with 24 nutrient solutions containing nitrogen Author: Grant Allan Bracher. Stem growth of Douglas fir began about 2 weeks earlier than in the Norway spruce at both sites.

At the nutrient rich site, most of the stem growth of both species occurred at the beginning of the season, while growth at the other site was more evenly distributed throughout the by: In Douglas fir, concentrations of sugars and several mineral elements in current-year foliage are correlated with tree age (Figure 1, Figure 2, Figure 3).Levels of total sugars, plus fructose and glucose, declined with increased age; xylose concentrations were not significantly related to age ().The macronutrients P, K, and Mg increased with age, whereas N, Ca, and S did not vary in relation Cited by: Mule deer group: Odocoileus hemionus subsp.

To test the hypothesis that N availability in the soil is enhanced beneath mixed species, the seasonal changes in different N forms were compared in humus (L+F+H) and soil beneath year-old Sitka spruce (SS) and mixed Sitka spruce-Scots pine (SS and SP) planted on a gleyed heathland by:   The growth of Sitka spruce (Picea sitchensis (Bong.) Carr.) on nutrient-poor sites in the British Isles is often improved during the late establishment phase when grown in intimate (‘nursing’) mixture with pioneer species such as pines and by: 2.

Pseudotsuga menziesii (Mirb.) Franco. Douglas-Fir. Pinaceae -- Pine family. Richard K. Hermann and Denis P. Lavender. Douglas-fir (Pseudotsuga menziesii), also called red-fir, Oregon-pine, Douglas-spruce, and piño Oregon (Spanish), is one of the world's most important and valuable timber trees.

It has been a major component of the forests of western North America since the mid-Pleistocene (30). The presence of mycorrhiza and protozoa also affected plant nutrient concentrations. In treatments with protozoa shoots of spruce seedlings contained less nitrogen, leading, e.g.

to an increased C/N ratio in needles. Conversely, in treatments with mycorrhiza concentrations of phosphorus in needles were increased by a factor of almost by: The medium pH level of plant tissue cultures has been shown to be essential to many aspects of explant development and growth.

Sensitivity or tolerance of medium pH change in vitro varies according to specific requirements of individual species. The objectives of this study are to 1) determine medium pH change over time in storage conditions and with presence of explants, 2) evaluate the Cited by: 3.One year old nursery stock of Douglas fir (Pseudotsuga mensiesii [Mirb.] Franco), western larch (Larix occidentalis Nutt.), and Engelmann spruce (Picea engelmannii Parry) were grown in the medium for 2 months and watered with nutrient solutions adjusted to 3 pH by: 1.
