Thriving of certain Clones of Arborescent Willows in the oppen Areas of the Lonjsko polje II Summary An article on the same title has been written the same experiment when the plantation was 6 years old (Šumarski list N° 1—3, 1975). In this article the reisults on thriving of certain clones at the age of 15 years of plantation have been given. According to the resultls we arrived ait the following conclusions: — At the age of 15 years of plantation the genotypic differences among the tested clones have (been established to regard to the survival and productivity under condition of flooding outside vegetation period ton the heavy gl eyed Isoil along the river Sava. — The experiment showed that in the case of White Willow there exists specific adaptability and it als for this ireaison that we recommend for the establishment of plantations of Arborescent Willowte in the area of low-land forests aloing the river Sava the following clones frocn the experiment: V 40, 11/1, iMP 1, V 39 and V 37. The stock volume of the mentioned clones /at the plantion age of 15 years ranged between 325 and 530 cubic metres peir hectare, alnld the average volume increment ranged between 22 and 35 cubic metres per hectare. The stock volume of ithe clone with the lowest production potential in the experiment amounted to 146,10 mS/ha, and the volume increment wals 9,74 rn3/ha. The experiment showed that Arborescent Willows along the iriver Sava also exhibit the function of precede plantations and give the possibility to the nai´urat regeneration of more valuable broad-leaved species such as Penduculate Oak (Quercus robur L.) and field Ash-tree (Fraxinus angustifolia Vahl.) on the area covered by Arborescent Willows. The mentioned clones of Arborescent Willows which have shown a very good adaptability and high production potential in the experiment together with newly selected clones suitable for growing aloing the river Sava give IUS the possibility to establish the multiclone plantations of Arborescent Willows which will possess a very high stability of ecosystem. |
