| 摘 要： | 菰是挺水型高大根茎禾草，是典型的无性系植物，在松嫩平原湿地条件下，野生菰分蘖节可繁殖２个世代，一般存活２年，最多存活３年。根茎一般存活１年，最多存活２年，无性系种群分蘖株和根茎均有２个龄级，并均以１龄级较大比重。其中，分蘖株为７４．１％，根茎累积长度为８９．４％，分蘖株立枯生物量为９２．８％，根茎生物量为９２．７％。

| Abstract: | Wild rice (Zizania latifolia), a rhizome grass species of high stem emerged plant, is a typical clone plant. Tillering nodes of wild species can propagate two generations and live 2 years in general, of which the oldest lives up to 3 years in the wetland conditions of the Songnen Plain China. The rhizome can live one year in general, occasionally up to 2 years. There are two age classes in both tillers and rhizomes of the clone population, and the 1st age class constitutes the majority, which are 74.1% tillers, 89.4% accumulative rhizome length, 92.8% dead standing biomass and 92.7% rhizome biomass. The potential clone population consist of rhizome buds of 0 age class and tillering node buds of 1 age class, of which 0 age class constitute the majority, 84.8%. The number of vegetative buds is 10 times more than the tillers. The clone population has a great popentiality for growing rapidly. |
