[Matter production and storage of Leymus chinensis clonal populations in restoration succession process of flooded meadow in Songnen Plain of China].
In this paper, the tiller matter production and the rhizome matter storage of Leymus chinensis clonal populations in the patches with radius of 0.5, 1, 3, 5 and 10 m were studied in the restoration succession process of flooded meadow in Songnen Plain. The results indicated that in each patch, 1 and 2 age classes had the most tiller matter production, while in the patches except in the center of 10 m patch, the rhizome matter storage of 1 age class was predominant. The proportion of the matter production and storage increased with increasing patch radius. On the whole, young tillers and rhizomes had vigorous matter productivity and storage capacity. From the center to the edge of each patch, the matter production and storage were consistent with the trend of patch expansion, and the variation of tiller matter productivity and rhizome matter storage capacity was the biggest at the edge of each patch. The matter production and storage strategies of L. chinensis clonal population modules settled the matter basis for population expansion and progressive succession of community in the restoration succession process of flooded meadow.
