Abstract:
With population of Limonium aureum in flat sandy land as research object,the influences and dependencies of individual growth differences on reproductive biomass and reproductive allocation of reproductive shoots，flowers and seeds in Limonium aureum were studied by standardizating its size according to canopy and height in this paper.The results showed that,there were significant or very significant linear correlations between the biomass of the reproductive modules and the change of the canopy and height.Among them，the productive shoots increased significantly and the flowers took second place，which took up the absolute advantage，but the seeds increased slightly，and the biomass ratio of the reproductive modules were 6.7∶5.3∶1.There were significant logarithmic correlations between the allocation of the reproductive modules and the change of the canopy and height，the allocation of the reproductive shoots was negative logarithmic relationship，and the allocations of the flowers and seeds were positive logarithmic correlation.It also showed that the reproductive shoots had mutual restriction with the flowers and seeds in the reproductive resource allocation.there were many significant or very significant correlations among the reproductive growth including the canopy and height，the reproductive biomass including the reproductive shoots，flowers and seeds and the reproductive allocation including the reproductive shoots，flowers and seeds，but the reproductive shoots allocation had not significant correlation with its height.And the reproductive shoots allocation had a negative correlation with other elements，which showed that the reproductive shoots allocation had mutual restriction with other elements.
