摘  要：
以5种红树林植物为研究材料,分析测试其叶片相对叶绿素含量(SPAD值),并比较红树林树种、样区对其叶片SPAD值的影响。结果表明,各样区、各树种以及单株之间SPAD值均存差异,对不同样区进行多重比较,可将其分为7类,5个红树林树种在叶绿素含量上差异较明显。各树种中以秋茄Kandelia obvolata最大(70.4),其次是红海榄Rhizophora stylosa(65.9)和木榄Bruguiera gymnorrhiza(62.9),白骨壤Avicennia marina为51.9,最小为桐花树Aegiceras corniculatum(48.6),树种平均为60.5。试验分析表明,树种因子效应极显著(P<0.01),强于样区因子效应,说明红树林树种是影响其叶片SPAD值的重要因子,同时也表明不同的立地环境条件对叶绿素含量存在影响。5种红树林植物叶片SPAD值均与其树高、基径生长性状存在显著正相关。

摘  要：
Leaf chlorophyll contents(SPAD Value) in 5 species of mangrove plants were studied and compared by SPAD-502. The results showed that leaf SPAD values of mangrove plants had significant differences among plots and even in the same plant. SPAD values from 15 sample plots were grouped into 7 groups by Duncan's multiple range test of one-way ANOVA, meanwhile, SPAD values had also extremely significant interspecific differences. SPAD value of Kandelia obvolata was highest(70.4), those of Rhizophora stylosa, Bruguiera gymnorrhiza, Avicennia marina and Aegiceras corniculatum were 65.9, 62.9, 51.9 and 48.6 respectively, and the SPAD means of 5 species was 60.5. Best linear unbiased prediction was used to estimate of random effects, and the results showed that effect of species factor was very significant(P<0.01) and stronger than effect of plot factor, which meant mangrove species was a main factor influencing leaf SPAD value and indicated different site conditions had also effects on it. The correlation analysis showed that SPAD values in 5 species of mangrove plants had significant positive correlation with their basal diameter and tree height.
