Structure and growth pattern of Agrostis clavata clone modules in Changbai Mountain area
摘要
Abstract
Based on the investigation and measurement of the single clone randomly collected from large samples, this paper analyzed the structure and growth pattern of Agrostis clavata clone modules in Changbai Mountain area. The modules of A. Clavata clone at seed milk stage were consisted of vegetative and reproductive tillers, and the reproductive tillers had the largest number and biomass, occupying 93. 3% and 97. 1% of total, respectively. With the increase of cluster diameter, the number and biomass of reproductive tillers as well as the total number and total biomass of vegetative and reproductive tillers increased by power function, with the coefficients of determination being 0. 661-0. 712. The reproductive tillers number and biomass showed a linear increase with the increasing number and biomass of total tillers, and the coefficients of determination were 0. 997 and 0. 965, respectively.关键词
