Spatial And Temporal Dynamics Of Fruits Of Rosa Primula Bouleng Shrub In Changchun Region

Rosa primula Bouleng shrubs were studied on different orientations. The fresh and dry biomass of fruit and their diameter were sampled and mensurated. The ecological plasticity of fresh, dry biomass and their diameter on different orientation would be revealed. The dynamics of fresh, dry biomass and their diameter with growing season and growing rules of fruit biomass and diameter would be showed. The results indicated:Sunshine, temperature and moisture are important factors to biomass accumulation. In east, south, west and north of R. primula Bouleng shrubs with different sunshine, namely, different microenvironments, so the fresh and dry biomass of fruits and their diameter were different.Fresh and dry biomass of fruit and their diameter were ascending with growing season in fluctuation. The coefficients of variation for fresh and dry fruit biomass were higher than their diameters. Fresh and dry biomass of fruit and their diameter hand high plasticity in different orientations.The relationship of fresh, dry biomass and their diameter of fruits took on power or exponential allometry, and linear isogony, which were significant and very significant in east, south, west and north in two sites. On the whole, the linear and power functions were dominant in all relationships.With growing season, between fresh and dry biomass of fruit and their diameter took on linear and power, which were significant and very significant. Fresh and dry biomass of fruit and their diameter were completely corresponding relationships.
