In this preliminary experiment seeds of juniper from four stands in different elevations (1900, 2100, 2200, 2250 m) were subjected to two pre-treatments with different duration period: warm stratification for three-months followed by 45 days warm stratification followed by 45 days cold stratification, and six months with 90 days warm followed by 90 days cold stratification. In comparison to the other three stands, the stand 2100 above sea level had more vigorous trees from which the seeds were collected. After stratification, seed samples were subjected to a standard germination test according to ISTA regulations. Juniper seeds originating from the Kalamoun mountains showed with 92.5% a high percentage of empty seeds. The better quality of seeds with less empty seeds (87%) were found in the stand which included the more vigorous juniper trees in 2100 m above sea level. Germination of seeds was significantly dependant on the duration period of the warm and cold stratification. The six months pre-treatment with 90 days cold followed by 90 days warm stratification led to germination of all sound viable seeds. Germinated seeds yielded of the shorter stratification period was only 17%. The results indicated that there is a real lack of knowledge about the reproductive biology and activity of the Kalamoun populations of J. excelsa.

Species parameters were assessed in 42 sites of various aspects and altitudes using the distance method and line transect techniques. Results showed significant differences in juniper density among the sites with different aspects. The lowest level of species distribution was observed at 1880 m altitude. Average stand density, importance value and coverage were 28.76 trees/ha, 32.5 and 10.8%, respectively. Juniperus excelsa dominated the community; the most important associated deciduous species were Amygdalus orientalis, A. korschynskii, Crataegus azarolus, Prunus sp., Pyrus syriaca, Cotoneaster nummularia, Acer hermoneum, Berberis cretica and Rhamnus palaestina. Less important species included Astragalus sp., Artemisia sp., Salvia sp., Acantholimon sp. Signs of environmental stress were apparent on juniper trees and were reflected mostly in the decline in increment of annual growth rings. Juniper trees attained a height of 6.5 m and averaged 80 cm in diameter. Age of trees was estimated at 225 years. The results indicated that the juniper trees have been neglected, misused, over felled, overgrazed and deliberately set on fire. This reduced the extent of the juniper ecosystem and demoted its ecological value. It is suggested that a management plan be put in effect to ensure the ecosystem sustainability and juniper conservation.

Reprint Status: Date of Publication: 1983 Volume Identification: 10 Issue Identification: Page(s): Address/Availability: SredazNIILKh, USSR Location/URL: CODEN: ISSN: 0024-1113 Notes: Abstract: Data are presented on the large variations in thickness, width and length of seeds and 'berries' of three species of Central Asian junipers, viz. Juniperus semiglobosa, J. seravschanica and J. turkestanica. The seeds can be extracted from the flesh by rubbing the berries between two discs (one rotating, the other fixed). The biometric data on the berries and seeds can be used to determine the optimum gap between the discs so as to avoid damaging the seed. Data are also given on berry and seed weights, % flesh, and the crushing force of the berries and seeds. For J. semiglobosa the optimum gap is 5.5 mm (88% berries crushed, with only 1% seed damage); for J. seravschanica 6 mm (89%; 1.7%), and for J. turkestanica 10.5 mm (89%; 1.8%). With hand extraction seed damage amounts to 7.6-10.4%. The disc-type seed extractor has a throughput of berries of 127 kg/h.

Reprint Status: Date of Publication: 1985 Volume Identification: 3 Issue Identification: Page(s): Address/Availability: SredazNIILKh, USSR Location/URL: CODEN: ISSN: Notes: Abstract: Data are presented on the physical and mechanical properties of the arils and seeds of four Central Asian junipers, viz. Juniperus semiglobosa, J. turkestanica, and (together) J. seravschanica and J. turcomanica. Permissible forces that can be used in extracting seeds from the flesh of arils are calculated, and details are given of the design and basic parameters of an appropriate mechanical extraction process. Arils are dried to 6-25% m.c., screened, rasped between two metal surfaces, and then screened with a set of three screens having openings of 1.2, 2.5 and 3.2 mm. Some data are given from trials with a prototype machine. Sound seed was undamaged, and cleaning was good, with a throughput of 87.6 kg/h of arils.

Reprint Status: Date of Publication: 2003 Volume Identification: 612 Issue Identification: Page(s): Address/Availability: Plant Biotechnology Center, Baylor University, Box 669, Gruver, TX 79040, USA. Location/URL: CODEN: ISSN: Notes: Abstract: Several cases involving apparent discordance in morphological, chemical (terpenoids) and molecular data are discussed that relate to species of Juniperus. These examples include J. blancoi, J. mucronata, J. scopulorum, J. convallium var. convallium, J. convallium var. microsperma, J. excelsa, J. procera, J. pingii var. pingii, J. pingii var. carinata, J. recurva var. recurva, J. recurva var. coxii, J. squamata var. squamata, and J. squamata var. morrisonicola. In these cases, the morphological characters of several putative Juniperus species are essentially identical, yet terpenoids and/or molecular data separate some taxa previously merged. To reconcile these discordant data sets, a multidimensional perspective must be taken to evaluate the sum of these gene differences and then integrate these gene differences into the taxonomy. A three-dimensional model is presented to attempt to explain these perspectives.
