Abstract: The mature cones of Aleppo pine were collected during the first fortnight of March from Shankar Acharyas hill forest of Kashmir valley. The cones were packed in gunny bags and were brought to the laboratory of Faculty of Forestry, SKUAST-K, Shalimar. The 15 cones per experimental unit in three replications were used. Oven with rotator fan was used for the cones subjected to various seed extraction methods (T1-T6) at constant temperatures. Analysis of variance was carried out using completely randomized design. The seeds extracted by the different methods (T1-T7) were subjected to germination test in the laboratory. The experiment was laid out in completely randomized design. Among different seed extraction methods, the maximum seed extraction (per cent basis) in minimum number of days was recorded as 74.23 per cent and 63.03 per cent under treatment T6 (alternate dipping for 10 minute followed by drying at 50 OC) and T3 (dry heating at 50 OC for 24 hours), respectively. The significantly minimum rate of seed extraction of 1.12 per cent was observed when the cones were dried in the sun (T7). The almost similar trend was observed in both the years of investigation i.e. 2009 and 2010 (Table-1).
