Study on the biomass and allometry of Fritillaria cirrhosa of different ages

In this study, the organs of Fritillaria cirrhosa cultivated for different growth years were weighed, their characteristics and biomass proportions were compared, and normality tests and variance analysis were conducted. The regularity of biomass accumulation and allometric growth of F. cirrhosa was studied using Standardized Major Axis (SMA) regression analysis. We found that the biomass values of the organs of F. cirrhosa at different ages followed the order: bulb > leaf > underground stem > root. The biomass of bulbs and leaves increased the most during the fourth year, and the biomass of roots and underground stems increased the most during the fifth year. The biomass of the above- and belowground parts of F. cirrhosa increased with an increase in growing years, and the biomass of the aboveground parts was significantly different (P < 0.05). During plant growth, the ratio of the biomass of each organ to the total plant biomass changed, and there was a positive correlation between the biomass of each organ and the total biomass. Except for the five-year-old flower and fruit biomass and total biomass, the biomass and total biomass of all organs of F. cirrhosa in the other years showed allometric growth patterns, which provides a theoretical basis for their artificial production.
