heat formation -- synthesis -- protein level

Аннотация: Life never occurs without respiration, respiration must be essential to it. The primary meaning of respiration is the action of breathing, the inspiration and experation of a gas mixture, commonly air. Respiration of plants is connected with other processes such as heat formation and work, synthesis, protein level, photosynthesis, sault uptake, with energy flow. This book is for biologists/

Аннотация: In this study we analyze how the ion concentrations in forest soil solution are determined by hydrological and biogeochemical processes. A dynamic model ACIDIC was developed, including processes common to dynamic soil acidification models. The model treats up to eight interacting layers and simulates soil hydrology, transpiration, root water and nutrient uptake, cation exchange, dissolution and reactions of Al hydroxides in solution, and the formation of carbonic acid and its dissociation products. The paper also deals with the other questiones.

nitrogen -- analysis -- distribution

Аннотация: According to the available information, nitrogen is the nutrient element which is most often the limiting factor for the growth of forest trees in Scandinavia. This paper reports a preliminary investigation, carried out wth the intention of studying the uptake and translocation of fertilizer nitrogen labelled with N15 in young trees of Scots pine and Norway spruce. The investigation was not intended to obtain information on the fertilizer-nitrogen balance in the soil-plant system, nor was it expected to elucidate the quantitative relationships of the uptake nitrogen by forest trees in natural stand

Кл.слова (ненормированные):
water relations -- needle conductance -- scarification

Аннотация: The water relations in planted seedlings of Pinus sylvestris were measured to find out whether poor water uptake was an important factor affecting the palnting result.Seedlings were planted in the field on six different occasions. The soil was prepared in four ways: (a) Scarified patch, (b) A mound of mineral soil on the scarified patch, (c) A mound of mineral soil on a section of upturned humus, (d) No scarification. Needle conductance, needle water potential and plant water conductance (Gp) were measured on the seedlings during the period after planting (1-4 years). It was found that the planted seedlings suffered from water stress. Gp only being 2-46% of that in established references. Water uptake was reduced for several years after planting. Planting in mounds placed on mineral soil or in scarified patches favoured a high water uptake of the seedlings. The low water uptake of the seedlings after planting may explain the poor reforestation results frequently observed.

soil water potential -- soil temperature -- conductance -- needle

Аннотация: Seedling of Pinus sylvestris, grown in low humified peat, were exposed to different soil water potentials and soil temperatures. The water potential and temperature were controlled by the use of a semi-permeable membrane system, and the seedlings were placed in a growth chamber during the experiments. Needle water potential, needle conductance and plant water conductance were measured on the seedlings. When the soil water potential decreased to-0.1 MPa, the needle conductance decreased to about 25% of the maximum whereas the plant water conductance decreased even more. The results are discussed in relation to resistance to water flow in the soil and in the root-soil interface. Soil temperature did not markedly change the relative responce of needle conductance and plant water conductance and soil water potential. Water uptake was considerably lower at lower soil temperatures.

accumulation -- biomass -- litterfall -- nutrient -- peatland -- uptake

Аннотация: The fertilized stands accumulated more N,P,K and B than the unfertilized ones during the three-year study period. The increased accumulation corresponded to 35 % (52 kg/ha) of the N applied on the NPK fertilized plots, 10% (6 kg/ha) of the P, 25% (25 kg/ha) of the K and 10% (0.2 kg/ha) of the B on the PK and NPK fertilized plots. The increased amount of B released in litterfall after fertilization was equivalent to 4% of the applied B. Fertilization inhibited the uptake of Mn and Ca.
