Clonal plants grow horizontally by producing multiple physiological individuals (ramets). We studied clonal growth in a homogeneous environment using a dynamic spatial model based on a stochastic cellular automaton. We investigated different growth forms from the aspect of ramet mortality. Non-steady-state and quasi-steady-state cases were defined, and we determined the number of steps suitable for making a reliable difference between these two types of cases. This given number of steps was used when testing for the proportion of quasi-steady-state cases in 1000 repetitions. We also tested the efficiency of occupation in these cases. Our expectation was that higher occupation would be associated with lower ramet mortality. The results only partially verified this hypothesis. Though with increasing ramet mortality, the average number of ramets tended to decrease, it was not the lowest ramet mortality that resulted in the highest occupation. Our results showed that very low ramet mortality was unfavourable for the plant, as the spreading front and the area behind this front were so packed that the plant was not able to return and recolonize the vacated sites in the central area. This resulted in a lower proportion of quasi-steady-state cases and lower occupation in these cases. Our results may contribute to a deeper understanding of clonal plant growth and its limiting factors.

分株死亡率对克隆植物生长的影响。

克隆植物通过产生多个生理个体（分株）而水平生长。我们使用基于随机细胞自动机的动态空间模型研究了均质环境中的克隆生长。我们从分株死亡率的角度研究了不同的生长形式。定义了非稳态和准稳态情况，我们确定了适合在这两种情况之间进行可靠区分的步骤数。在测试1000次重复中准稳态情况下的比例时，将使用给定的步骤数。我们还测试了这些情况下的职业效率。我们的期望是更高的职业将导致更低的分株死亡率。结果仅部分验证了该假设。虽然随着分株死亡率的上升，分株的平均数量趋于减少，并不是导致最高分株的最低分株死亡率。我们的结果表明，非常低的分株死亡率对植物不利，因为蔓延的前部和该前部的后部区域非常拥挤，以致植物无法返回并重新定居中部的空地。这导致准稳态案件的比例降低，这些案件的职业减少。我们的结果可能有助于更深入地了解克隆植物的生长及其限制因素。由于蔓延的前部和该前部的后部区域都挤得水泄不通，以致植物无法返回并重新定居中部地区的空地。这导致准稳态案件的比例降低，这些案件的职业减少。我们的结果可能有助于更深入地了解克隆植物的生长及其限制因素。由于蔓延的前部和该前部的后部区域都挤得水泄不通，以致植物无法返回并重新定居中部地区的空地。这导致准稳态案件的比例降低，这些案件的职业减少。我们的结果可能有助于更深入地了解克隆植物的生长及其限制因素。
