Effects of Charcoal on Seed Germination of Larix gmelinii

doi:10.7525/j.issn.1673-5102.2017.01.014

Abstract

Abstract: To understand the effects of charcoal after forest fire on the germination of Larix gmelinii at Great Xingan Moutains, we investigated the charcoal distribution and collected different types of charcoal produced by trees(L.gmelinii and Betula platyphylla Suk.), shrub and grass, respectively. We collected charcoals produced by different years(1, 2, 4 and 5 year) from the burned forest sites. Then, the charcoals were soaked into water at 12, 24, 48 and 96 h to obtain different charcoal solution. There were significant effects of different charcoal and different produced years on the germination of L.gmelinii seeds. However, the strength and directions of effects were randomly, and the effects of charcoal were very completed.

Key words: charcoal, Larix gmelinii, seed germination, solution of charcoal
