CLONE ARCHIVE OF SILVER FIR IN THE MIĘDZYLESIE FOREST INSPECTORATE
Summary. The problem of silver fir restitution in the Sudety Mountains was focused on the lack of local seeds. Increasing the existing seed base is absolutely necessary. The easiest way to obtain it is the establishment of seed orchards, based on the maintaining trees, belonging to the local populations. This collection consists of 21 clones of the plus trees selected in the communal forests of Lądek Zdrój and located in Lądek Zdrój and the Bystrzyca Forest Inspectorates. Other clones (24) belong to the trees selected by Wilczkiewicz at the same locations. According to the survey from 2001 309 grafts remained (1-18 grafts in one clone), 111 grew up from roostocks and 33 trees formed their crowns with shoots both from grafts and rootstocks (“dual trees”). First cones harvest was done in 1995, 30 years after grafting and 28 years after establishment of the orchard. During this harvest 55 kg•ha-1 of cones were collected what means ca. 5.5 kg of seeds per hectares. Later harvests were irregular but they were better. In 2003, 1359 kg•ha-1 of cones were harvested (136 kg of seeds per hectar). From the whole area 2450 kg of cones and 245 kg of seeds were collected. In 2004 the crop was much lower: only 516 kg•ha-1 of cones and 63 kg•ha-1 of seeds were collected. In 2005, 943 kg•ha-1 of cones and 117 kg•ha-1 of seeds were collected. Between 1995 and 2005 the seeds crops were observed seven times, and 3657 kg•ha-1 of cones (366 kg•ha-1 of seeds) were collected in total. Average crop was 332 kg•ha-1 of cones and more than 33 kg•ha-1 of seeds. However seed crops on the studied seed orchard are irregular and that makes planning very difficult. The data on the potential cone and seed productivity of silver fir grafts are presented for the first time in Poland.
