%X <p>In order to understand the growth rate of <i>Pinus yunnanensis</i> Franch seedlings and the life history strategy of seedlings， the allometric growth of <i>P. yunnanensis</i> Franch. seedlings from different families was studied. The 49 annual families of <i>P. yunnanensis</i> were selected as materials， the allometric growth analysis method was used to the allometric growth of seedling height and ground diameter. The results showed that different families had different allometric growth index. The allometric growth index of 28 families was 1.0， which was in accordance with the geometric similarity model， and the other 21 families were allometric growth relationship. The results also showed that there were both allometric and isokinetic growth in seedling height and ground diameter among different families. Therefore， the difference of allometric growth mainly come from genetic differences， which reflected the resource utilization strategy of seedlings by adjusting their own resource allocation.</p>
