Quantitative Character of Puccinellia tenuiflora and Puccinellia chinampoensis and the Relationship between the Character and the Clone Size of Two Puccinelila Populations at Reviving Stage in the Songnen Plain

ZHANG Li-hui et al (Department of Biology,Changchun Teachers College,Changchun,Jilin 130032)  
Through the sample and investigation of single tufts of Puccinellia tenuiflora and Puccinellia chinampoensis,in the paper the quantitative characters of two Puccinelila populations and the relationship between the character and the clone size at reviving stage in the Songnen Plain were analyzed.The results showed that the tuft size and total tillers of P.chinampoensis population were higher than those of P.tenuiflora population.The tuft size and total tillers of P.chinampoensis were 2.78 times and 3.76 times of P.tenuiflora.The winter tillers were dominant,which were 64.7% and 69.5% in two populations.Two populations lived mainly through the winter by winterness seedlings and by buds at the same time.The rate of survival through the winter was 73.1% and 100.0%,respectively.With the increment of tuft size of two populations,the correlations between winter tillers,spring tillers and total tillers and the tuft size of two populations were very significant differences(p0.01),and winter tillers,spring tillers and total tillers were exponentially increased by the ratios of 1.303 9,0.965 9,1.171 7 and 0.408 5,0.505 7,0.367 2,respectively.
