ABSTRACT
Allepo pine is an exotic conifer introduced in Kashmir valley, which can play the vital role in restoration of degraded areas and has the ability to fulfill the minor need of local inhabitants due to its fast growth, long and high fiber content per hectare which is important for pulp and paper industry keeping in view the importance and constraints of regeneration and germination of this species the study was undertaken to investigate the effect of cone collection date on cone, seed and germination as its cone are hard to open which affects the natural regeneration of this valuable exotic pine in its natural habitat at faculty of forestry, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar. The experiment consisted of 16 treatments/collection dates from 15th August to 1st April and was laid out in completely randomized design. The study conducted on maturity indices revealed that seeds were mature when the cone color changed from green to glossy red-brown at maturity on 1st March onwards. The minimum fresh cone weight of 53.86 g and cone-specific gravity of 0.91-0.87 was recorded on 1st April. The maximum seed weight of 3.09 g/100 seeds (g) was recorded on 15th March and remained constant afterward. Whereas maximum germination percent of 43.25 % was recorded 15th February and remained constant afterward. Therefore, the cone color should be considered as an important index of ripeness. The cone should be collected in the month of March when color of cone turns glossy red-brown.
Key words: Allepo pine, Pinus halepensis, Cone, Maturity indices Germination.
