5种红树林植物叶片SPAD值比较
Comparison on SPAD Values of Leaves in Five Species of Mangroves
摘要
Abstract
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.关键词
