Dear colleagues and customers,
After the start of the gathering of cones in 2016 with the most early dispersing species of the pine family, namely the scrub pine ( Pinus mugo mughus ), we were hopeful of some good results. The harvest was strong, and the samples for yield and germination rate taken from the West Rodopi and Rila mountains showed more than satisfactory results.
On the whole, we are pleased with the quantity and quality of the gathered scrub pine seeds. The laboratory samples showed 91% germination rate, while we strive for the purity to be above 97%.
The results from the white pine ( Pinus sylvestris ) are also good. The year for the white pine is not full seed-bearing, but still there is a satisfactory quantity of cones. We have samples taken from quite a few seed-producing sources – seed-producing plantations and seed-producing gardens found in the West Rodopi.
The cones we gathered and those that are still to be gathered are from the best and most elite plantations in the region.
The results from the yield samples vary between 1.7% and over 2%, which is more than good for a species such as the white pine.
After the goods results from the scrub pine and the white pine, it is the pitch pine’s turn, which proved a real challenge this season. The harvest is exceptionally poor, and besides, we encountered another problem, too – a large percentage of empty seeds.
The percentage of empty seeds in the laboratory samples made is about 70%. This automatically cut the yield down to about 0.6 – 0.7 %, which is a poor result for the pitch pine, given a targeted minimum yield of 3% according to data from studies. The samples that showed poor results are from the region of the Southwest Rodopi and the eastern part of the Pirin mountain area. The harvest is a little better in the region of the Kraishte-Ihtiman area, where it was rated “3” on the Kaper scale and “4” on the Korchagin scale.
The campaign for gathering seeds from the Norway spruce (Picea abies) was also thwarted by the poor harvest, which according to the competent foresters with whom we work, is due to late-spring cold spells and frosts at the time of spruce florescence.
The mentioned data are for the West Rodopi region.
We were able to gather a certain quantity of seeds from the European silver fir (Abies alba), which seeds, after laboratory samples, were rated as second category with a lower germination rate. The harvest was not good, but the collected quantity of cones gave a high yield of 8%. The gathered quantity of cones was from the West Rodopi region.
On the whole, the year for the coniferous plants was not a strong one. The gathering is not finished yet, and we hope to be able to derive the maximum.
