Morphological diversity of Puccinellia tenuiflora and its relationship with the environment in Song Neng Plain

摘要：

This study examined morphological variation diversity with environment of 6 populations of Puccinellia tenui f lora in Song Neng plain.Each population had 25 ～ 30 individuals.The results showed that environmental factors had obviously effects on the morphology, especially rainfall and temperature.The plant height and other parameters increased as the rainfall and temperature increased.It is concluded that greenhouse effect may have the same impact on morphological diversity of Puccinellia tenui f lora as climatic conditions.
