The Relationship Between the Nariations of Fruit-Bearing Organic Characters in Natural Aneurolepidium chinense Population and the Climatic Factors in the Songnen Plain of China

Yang Yun-fei and Zhu Ling   

Abstract: Based on eight years continuous observation and measurement on the ways and intensity of utilization of three fixed plots of the meadow of natural Aneurolepidium chinense in the Songnen Plain of China at definite stage of annual growth season the quantitative analysis on the relationship between the variations of fruit-bearing organic characters of A. chinense population and the climatic factors was investigated. Change of climate was one of the comprehensive factors which led to the variations of fruit-bearing organic characters of the population in different plots, but variations on the characters of the population among the plots and on the degree of correlation or functional relationships between the character and the climatic factor in different stages were only caused by the ways and intensity utilization. The characters of the spike organ were more affected by climatic factors in the stage of growth and development of the winterness plants of the population. There were universal ecological effects of time lap in the climatic factors.

Key words: Aneuroletridium chinense populations, Fruit-bearing organic character, Climatic factor, Meadow
