Abstract

To standardize maturity indices in Pinus gerardiana, the seeds were collected from three diameter classes at two week interval starting from 23rd August to 18th October (5 collection dates). Cones and seeds extracted during each collection were subjected to various physico-chemical and germination studies. For best maturity, the cones should be collected on 4th October when these are greyed-orange in colour and cone and seed moisture contents are 43.09% and 27.90%, respectively. At this stage, the seeds exhibited maximum germination (73.23%), germination energy (46.20%), germination value (3.11), and germination index (2.07) revealing highest total sugar content (96.27 mg/g).
