The morphological differentiation of Poa glauca (Poaceae).

摘要

The morphological differentiation of Poa glauca was studied using data from samples of three geographical races (Scandinavian, North Siberian and South Siberian). 436 plants were measured. The variation of three quantitative and 19 metric charactersof stem, leaves, panicle and spikelets was analysed. The analysis of morphological character variation showed that the divergence between the three studied races is significant. However, all morphological characters overlapped which contraindicated subdivision of Poa glauca into three species.
