Abstract

Mycoflora associated with different seed sources of Pinus wallichiana.

Abstract

This study was conducted to determine the associated mycoflora in different seed sources of Pinus wallichiana from Uttaranchal and Himachal Pradesh, India, in order to obtain quality and healthy seedlings. Cones of P. wallichiana were collected from four seed sources of Uttaranchal namely Gangnani, Devrana, Gangotri and Harsil, and six seed sources of Himachal Pradesh namely Sarhan, Sawat, Dodra, Larot, Kufri and Kharapathar. The results showed that there were 10 fungi species present in the Uttaranchal seed source, Aspergillus flavus, A. niger, Cladosporium cladosporoides, Mucor fragilis, M. globosus, Penicillium sp., P. melinii, Rhizopus stolonifer, Syncephalastrum and Trichothecium roseum. A total of 15 fungi species were recorded from Himachal Pradesh, namely Alternaria alternata, Aspergillus flavus, A. fumigatus, A. niger, Blastomyces sp., Curvularia lunata [Cochliobolus lunatus], Mucor sp., Papularia sp. [Apiospora], Penicillium sp., P. citrinum, P. griseum, P. tardum, Pythium sp., Rhizoctonia bataticola [Macrophomina phaseolina], and Rhizopus. Seed source Kufri reported maximum number of mycoflora, i.e., 9 fungi, while in Sawat and Kharapathar, only one fungus was recorded, Aspergillus niger.
