Effect of planting and scarification on the water relations in planted seedlings of Scots pine
[Text] : научное издание / G. Orlander. - Uppsala : The Swedish University of Agricultural Sciences, College of Forestry, 1986. - 17 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 173). - eng. - Библиогр.: с. 16-17. - ISBN 91-576-2691-X : 1.00 р.
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.

Water relations of seedlings of Scots pine grown in peat as a function of soil water potential and soil temperature
[Text] : научное издание / G. Orlander, K. Due. - Uppsala : The Swedish University of Agricultural Sciences, College of Forestry, 1986. - 13 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 175). - eng. - Библиогр.: с. 12-13. - ISBN 91-576-2708-8 : 0.50 р.
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.

Acacia mangium: studies on the genetic variation in ecological and physiological characteristics of a fast-growing plantation tree species
[Text] : научное издание / L. Atipanumpai. - Helsinki : The Society of Forestry in Finland-The Finnish Forest Research Institute, 1989. - 92 p. : рис., табл. - (Acta Forestalia Fennica ; vol. 206). - eng. - Библиогр.: с. 83-92. - ISSN 0001-5636. - ISBN 951-651-085-X : 5.00 р.
Кл.слова (ненормированные):
carbon dioxide compensation point -- heritability -- water stresssmall-scale entrepreneur -- dendrometry -- dark respiration
Аннотация: Genetic variation in the physiological characteristics and biomass accumulation was studied in both field and laboratory conditions. Variation in the growth characteristics, foliar nutrient concentration, phyllode anatomy and stomatal frequency was analyzed in 16 different origins under field conditions in Central Thailand. Family variation and heritability of growth and flowering frequency were calculated using 20 open-pollinated families at the age of 28 months. The effect of environmental factors on diameter growth in different provenances is also discussed. Under laboratory conditions, such physiological characteristics as transpiration rate, leaf conductance and leaf water potential were measured at varying soil moisture conditions. The responses of photosynthesis, photorespiration and dark respiration as well as the CO2 compensation point to temperature and irradiance were also investigated. All physiological characteristics indicated differences among provenances. An attempt was made to relate the results obtained in the laboratory to the growth performance in the field. Recommendations on provenance selection for the planting of A.mangium in Thailand are also given.
