The mean volume of stands with fir and beech in their species composition in the study plots Święty Krzyż 1 and Święty Krzyż 2 was 521 m3/ha and 203 m3/ha respectively. These stands were many-storeyed and of many generations with the structure of the distribution of trees by d.b.h. close to Liocourt-Meyer curve. In volume of standing dead trees and dead wood laying on the ground, amounting together to 41.1% of stand volume of living trees in the plot Święty Krzyż 1 and 171.6% in the plot Święty Krzyż 2, predominated fir 99.4% and 100% in total volume of standing dead trees, and 46,2% and 82% in total volume of laying dead wood in respective plots. Fir was most abundant in the new growth layer (78.3% in the plot Święty Krzyż 1, and 39% in the plot Święty Krzyż 2), while beech decidedly dominated in the upgrowth layer (54.2% and 50.8% in respective plots). The stand in the plot Święty Krzyż 1 was considered to be in the growing up stage with the phase of storeyed form, while the one in the plot Święty Krzyż 2 in a transitional stage between the break up stage and the growing up stage with an inter­mediate phase between the regeneration phase and the phase of storeyed form.

During 1983-1989 late cleanings were carried out in silver fir up-growth. Cuttings based on a positive selection had the most benefical effect on the biomorphological characteristics of silver fir up-growth. They were most intensive and led to increased increment in diamater of the stem and length of the crown, and also to storeyed structure of the up-growrh. Promotion of the most valuable individuals which in future should form the overstorey of the stand is also an important advantage of this treatment. In comparison with the control treatment the negative selection had a statistically significant effect on the height and diameter increment, change in absolute length of the crown and its height above the ground, as well as the number of its whorls. However, the negative selection led to disappearance of height differentiation in the silver fir biogroups.

Tending operations were carried out in about 20 year old silver fir upgrowth in 1983 and 1989. They were evaluated in 1995 when different biomorphological characteristics of young firs were analysed. The operations based on the positive selection stopped the process of crown reduction and resulted in increased diameter increment. In case of firs in the lower tree layer they also resulted in increased height increment. Trees in the combined variant reacted with increased diameter increment and formed longer crowns. However, the combined treatment led to disappearance of natural height differentiation of the upgrowth and simplification of its structure which in conse­quence reduced its potentiality for practical utilisation. The negative selection in comparison with the control variant had no significant effect on the biomorphological characteristics of tree.

The paper presents the results of multivariate analysis of Scots pine cones collected in stands, which presumably originate from local sites of the Carpathian Mts. and the Sudety Mts. The aim of the study was to classify the analyzed stands to homogeneous groups in respect to cone traits. On the basis of measurements, three groups of populations in the Carpathian Mts. and the Sudety Mts. were determined: lowland (N), mountain (G) and foot-hills (P). The cones of the foot-hills pine are the biggest, the least full and have fewer long, wide and thick scales. The cones of lowland pine are the same size like ones of the foot-hills pine but they are more full and have numerous flat scales. Mountain pine forms the least cones however they are similar to the foot-hills pine in respect to dimension proportion. The foot-hills pine and mountain pine are characterized by smaller 1-year old cone setting angle in comparison with lowland pine. Distinguished morphological types are suitable for different geographical regions (given in the paper). No differences were found between pines from the Carpathian Mts, and the Sudety Mts., which were classified into the same morphological types (the foot-hills and mountains). In respect to cone morphology, Sudetic and Carpathian pine stands do not create different groups of origin. The stands where typical cones for lowland pine stands predominate (above 50%) were not found in the Sudety Mts.

The studies were carried out in stands of the Carpathian Mts. and the Sudety Mts., where pine is a dominant species. The selected pine stands were probably of local origin. The aim of the studies was the characterization of chosen site and stand traits and morphology of pines on the basis of about 20 dominate pine trees. Very low cone crop and the lack of natural pine regeneration on the one hand, and cases of climax species regeneration on the other were found in the stands. Sometimes pine enclaves occupied small areas (1/3, 1/2 ha) in the studied stands. The number of pines often amounted to about 100 per ha. The studied stands were characterized by high stability (80% of trees showed the ratio of height to D.B.H. (H/D) between 45 and 80), large diversity of stem quality (36% of trees were qualified as class A), some significant heights (up to 37 m) and good vitality. When compared to the Carpathian ones, Sudetic pine stands grew on poorer sites and on average were characterized by older age, lower values of all analyzed traits (of stems, crowns and needles), lower iron content in needles, higher stem quality (81% of trees in class A in Sudetic stands, 24% of tress in class A in Carpathian stands) and better vitality. Pines from the Sudety Mts. were distinguished by the shell-shaped type of bark, which occurs very seldom in the Carpathian Mts.

Results of the study on impact of the late ground frost on cones of Larix decidua Mill. and cono- and seminiphagous insects: Strobilomyia laricicola (Karl) and Megastigmus pictus (Först.) are given. On 120 twigs, each 1 m in length, the distance of cone from twig apex was measured. It was determined which cones were not damaged by frost, and which were dead. The data obtained were subjected to a statistical analysis using the Kolmogorov-Smirnov's test, Stu­dent's t-test and U Mann Whitney's test. No unequivocal correlation was found between position of a cone on the twig and the effect of low temperature. The late ground frost destroyed 218 cones (61,6%) of a 357 analysed. It was found that the mature cones (not destroyed by the late frost) often (56,1%) were inhabited by S. laricicola. Seeds extracted from these cones, were dissected, and it was found that seeds were infested by M. pictus. This seminiphagous insect destroyed from 0,6% to 7,2% of seeds (3,3% of 3000 analysed). The cones were collected in southern Poland from 30 larches on six localities (5 in each loc.) in a national park, seed plantations and in a managed stand during the growing season of 2001.

The purpose of the research was to study some of the features of silver birch, in its habitat conditions, as a naturally occurring pioneer crop appearing in open spaces formed by the disintegration of the Norway spruce monocultures in the Silesian Beskid Mountains. On the three research plots the occurrence of the young natural regeneration and understorey of 13 species of trees and shrubs was determined. On the basis of the number of specimens it was found that the most dominant species in the whole area was Norway spruce (56-64%). Birch accounted for 14-16%, and all pioneer species (Betula pendula, Populus tremula, Pinus sylvestris, Salix caprea, Sorbus aucuparia) accounted for 21-23%. However, the researched plots are generally covered by birch due to the share of this species amounts to nearly 90% in the height classes above 0.5 m. The birch appeared within 4-6 years of the disintegration period of the spruce stand. The succession of the birch, its quick growth and ability to develop a crown confirm the possibility of using this species as a pioneer crop. Climax species (silver fir and common beech) can be introduced to a seven-year-old birch pioneer crop, depending on the birch vitality, with the assumption of the conversion period of 30 to 40 years. In the case of the birch vitality abatement the suggested period of conversion will have to be shortened.

On the basis of cone traits, three groups of Scots pine populations: lowland (N), mountain (C) and fool-hill (P) were distinguished in the Carpathian Mts, and the Sudety Mts. (Skrzyszewski 2001b). The aim of the study was to determinate the morphological and increment traits of population groups, which were of the highest discriminating power in interpopulational comparison regardless of group division based on cone morphology. The traits related to high quality of stem (tree height, short and narrow crowns with fine branches which fall off the stem quicker, less slenderness of stem and thinner bark) are more characteristic for the foot­hill pine and less for mountain pine. Pines of those populations form narrower annual D.B.H. increment in the same periods of life. Lowland pine (N) is characterized by the largest diameter increment and the largest differentiation of studied trails, and probably by the greatest plasticity. Regardless of the stand division done on the basis of cone morphology, stem and crown traits, which are crucial for production value, are of the highest discriminating power. The studies indicate that environmental factor is more significant than factor of origin. From the quality point of view, the foot-hill pines are marked by the best silvicultural traits.
