| الوصف: | Forests of the pedunculate oak (Quercus robur L.) management class in the Republic of Croatia cover an area of approximately 200,000 ha. In view of the size of the distribution range, the total growing stock amounting to over 48 million m³, the annual current increment of 1 million m³ and morphological differentiation, the study of pedunculate provenances is of exceptional importance. Clonal seed orchards were established with the purpose of achieving frequent yields, obtaining genetically valuable seed material and preserving the genetic variability, which lessens the possibility of local population disappearance caused by changed environmental conditions or the occurrence of new diseases and pests. Samples of seed material with a total of 49 different clones were collected from the 2015 yield in the „Plescice“ clonal seed orchard of pedunculate oak (Quercus robur L.) and one-year-old container seedlings were grown under controlled conditions. Dry mass content of leaves, stems and roots was measured in the samples containing 5 seedlings of each clone. Their morphological differences and variability were determined and the clones whose seedlings showed poor potential for the use in biological forest regeneration were defined. Mean dry mass of roots lower than 2.0 g was found in the samples of 6 clones, while 4 of them showed an unfavourable ratio of dry matter of the above-ground part and dry matter of the root system, leading to the assumption that the seedlings of these samples might have potentially poor reception in the field, poor survival and initial growth. |
