【摘要】 [Objective] To study the flowering biomass allocation of Lilium sulphureum Baker apud Hook.f.,so as to provide references for field management and reasonable harvesting of this resource.[Method] The biomasses of different modules of wild Lilium sulphureum Baker apud Hook.f.produced in Wuchuan County of Guizhou Province were quantified.Correlation test and regression analysis on experimental data were carried out by SPSS software.[Result] The order of biomass allocation of single organ was bulb scales>aboveground stems>leaves>flowers>belowground stems>stem roots>scale seats or basal roots.The maximal biomass was invested in bulb scales whether in fresh weight (33.4%) or dry weight (41.2%).The dry weight biomass of bulb scales had extremely significant positive correlation with the basal diameter,plant height and other modules (P<0.01).The dry weight biomass allocation of bulb scales had significant negative correlation with the stem and the propagation module (flower) (0.01<P<0.05).[Conclusion] The growth of a plant was assorted with the nutrition allocation and materiel accumulation.The effect of propagation module and stem on the growth of bulb scales should be controlled in the artificial cultivation of Lilium sulphureum Baker apud Hook.f.
