Effects if Types of Inocula and Seed Sources on Mycorrhizal Formation and Initial Growth of Pinus Merkusii Jungh et de Vriese Seedlings in Sterile and Unsterile Soils
Dissertation Abstract:
Seedlings of Pinus merkusii Jungh et de Vriese were grown under screenhouse conditions in Yogyakarta, Indonesia for 7.5 months. The effects of soil treatment, seed sources, and mycorrhizal inoculation on initial growth and mycorrhizal formation of the seedlings were studied.
Sterilized soil significantly affected the initial growth in terms of height and dry weight, but not diameter and root/shoot (R/S) ratio of the seedlings. Sterilized soil was found to be superior than unsterilized soil.
Seed sources affected initial growth in terms of the height, dry weight, and diameter but not the R/S ratio. East Java seed sources were superior to the Central Java seed sources. Inoculation treatment did not significantly affect initial growth; however, few mycorrhizal seedlings were observed in those inoculated with Pisolithus tinctorius and grown in mycorrhizal soil.
