Abstract

Pinus wallichiana dominated forest communities, located in the Hindukush ranges of Swat, Pakistan were analysed for variability in the cone and seed traits. The results disclosed significant variability in mean values, critical difference, co-efficient of variation, broad sense heritability,...

Abstract

We investigated the phytosociology, structure and dynamics of Pinus roxburghii in 40 stands in northern areas of Pakistan by using cluster analysis (Ward's agglomerative clustering) and ordination (Nonmetric Multidimensional Scaling). Cluster analysis revealed three major groups associated with...

Abstract

The climate/growth relationships of four gymnosperm tree species growing in seven catchments in the Indus Basin of the Karakorum range, North Pakistan, were evaluated for using two versions of tree-ring chronologies: "standard" and "residual" chronology. The growth of the trees was compared to...

Abstract

A collection of 28 tree-ring chronologies from six different species located in northern Pakistan were evaluated in terms of their potential for dendroclimatic reconstructions. 15 of the sites are new while the remaining 13 (all Juniperus excelsa M. Bieb.) have been reported earlier. Several...

Abstract

Standardized ring-width chronologies of Pinus wallichiana A.B. Jackson and Pinus gerardiana Wall. ex Lamb., are presented, covering maximum period from AD 1300-2000 and 1400-2000 AD respectively. These chronologies are based on highly correlated (0.636) and crossmatchable wood samples. Response...
