在大田条件下，对3个不同大小的刺桐个体（其中1个为开花个体）的生长过程进行了观测。他们模拟的数学模型报告在以前的文件本系列（横井，1976年）。模拟很好地描述了三个个体的实际生长。该植物繁殖的两个方面，种子生产和常年生长的鳞茎，也进行了模拟。模拟结果表明，该种植物在萌发后的非开花期长达9 ~ 10年。该种群的个体大小分布与模拟结果吻合较好。这一研究定量地阐明了春季短命植物的生命机制，并显示了前人所报道的数学模型的优点。
Growth process of three different sized individuals (one of them was a flowering individual) ofErythronium japonicum was surveyed in a field. They were simulated by the mathematical models reported in a previous paper of this series (Yokoi, 1976). The simulations described well the actual growth of three individuals. Two aspects of reproduction of this plant, seed production and perennial growth by bulb, were also simulated. The information obtained from the simulations indicated that this plant has to spend nine or ten year-period in the non-flowering stage after germination. Distribution of individual size in this plant population agreed well with the results obtained from the simulation. This investigation made clear the mechanism of life of a spring ephemeral quantitatively, and showed a merit of the mathematical models reported in the previous paper.
