6种红树树种生长与叶片元素含量及化学计量特征
|
摘要
为探讨红树林树种生长与叶片元素含量特征,比较木榄(Bruguiera gymnorrhiza)、角果木(Ceriops tagal)、正红树(Rhizophora apiculata)、红海榄(R. stylosa)、白骨壤(Avicennia marina)和桐花树(Aegiceras corniculatum)6个树种成活率、生长量、叶片元素含量及化学计量。结果表明,栽植120 d后,6种红树树种的成活率均在85%以上;苗高净生长量在2.60～10.32 cm之间,地径净生长量在8.62～16.92 mm之间,以桐花树和正红树的生长较快。白骨壤的叶片N含量最高,角果木K含量较高,红海榄Ca含量较高;6种红树叶片N/P值均小于14,属于N制约型植物;叶片化学元素K/P、N/K、Ca/K、Ca/Mg和K/Mg的值存在一定程度的差异。PCA分析结果表明,6种红树树种均能较好地各聚为一类,每个树种对其生长量因子、叶片元素含量因子和化学计量因子响应不同。
The paper evaluate the growth and leaf element content of mangrove species. The survival rate,growth, leaf element and stoichiometric characteristics were detected in Bruguiera gymnorrhiza, Ceriops tagal,Rhizophora apiculata, R. stylosa, Avicennia marina and Aegiceras corniculatum. The results showed that the survival rate of six mangrove species were all above 85% after 120 days. The net growth of seedling height were2.60-10.32 cm, and the net growth of ground diameter were 8.62-16.92 mm, which Aegiceras corniculatum and Rhizophora apiculata were growth faster. The leaf N contents of Avicennia marina was highest, the leaf K contents of Ceriops tagal was higher, and the leaf Ca contents of R. stylosa was higher. The N/P ratios of six mangrove species leaf were less than 14, which indicated N concentration was a major limited factor for plant growth. There was a certain degree of different in the ratios of K/P, N/K, Ca/K, Ca/Mg and K/Mg. The results of PCA analysis showed that all the six mangrove species could be clustered into one class. Each species responded the difference to its growth, leaf element content and stoichiometric factor.
