摘要:
 在福建省洋口国有林场研究了20个光皮树优良家系幼苗叶片氮（N）、磷（P）化学计量特征及其与土壤养分因子的关系。结果表明：光皮树不同家系之间叶片N含量为11.75~17.09 mg·g-1，平均为14.62 mg·g-1；叶片P含量为0.76~1.18 mg·g-1，平均为0.93 mg·g-1；叶片N/P为13.44~18.03，平均值为15.82。多数家系（16~18个）之间叶片N、P含量及N/P没有显著差异，尤其是叶N/P变异较小，表明总体上叶片化学计量特征在光皮树不同家系之间是相对稳定的。因此，光皮树叶片化学计量特征具有种内相对稳定性。叶N含量与土壤水解N（AN）含量呈显著正相关，叶P含量与土壤有效P（AP）以及叶片N/P与土壤AN/AP之间均没有显著相关性。因此，叶片N/P并不能作为光皮树营养限制的唯一指标，结合土壤养分特征才有助于光皮树营养需求的综合评判。
Abstract:
 Leaf nitrogen (N) and phosphorus (P) stoichiometry of 20 Cornus wilsoniana families and their relationships with soil nutrients were studied in Yangkou National Forest Farm,Shunchang,Fujian Province.The results showed that the leaf N content among 20 C.wilsoniana families varied from 11.75 mg·g-1 to 17.09 mg·g-1,14.62 mg·g-1 in average; leaf P content varied from 0.76 mg·g-1 to 1.18 mg·g-1,0.93 mg·g-1 in average; leaf N/P varied from 13.44 to 18.03,15.82 in average.Leaf N,P contents and N/P were no significant difference among the majority of the families (16-18 families),especially the variation of N/P ratio was relatively small,suggesting that the leaf N,P and N/P were relatively stable among different C.wilsoniana families.Therefore,intrinsic homoeostasis was the stoichiometric characteristic of C.wilsoniana families.Leaf N content had a significant positive correlation with soil alkaline hydrolysable N (AN),no significant correlation was found between leaf P content and soil available P (AP) or between leaf N/P and soil AN/AP.Leaf N/P ratio could not serve as the only indicator of nutrient limitation,to conduct comprehensive evaluation on plant nutritional needs,soil nutrient characteristics should be considered.
