aboveground part

基本解释

The underground rhizome of P. australis and the aboveground part of S. mariqueter were the main sites of existing carbon storage.
地下根茎为芦苇现存碳储量的主要场所，而地上部分是海三棱藨草碳储量的主要场所。
Compared with the aboveground biomass, however, only limited studies concerned the underground part due to complexity of roots systems and difficulties in root biomass measurement.
随着人们对生态系统物质循环和能量流动研究的进一步深入，地下生物量的研究渐成生态学的研究热点。
Staying the decrease of the polysaccharide content of underground part and the total flavonoids content of aboveground part, increased polysaccharide and total flavonoids content in harvest.
延缓地下部分多糖和地上部分总黄酮含量的降低，增加其收获期多糖和总黄酮含量。

地上部分
In late growth season(September),the iron content in C. angustifolia,C. meyeriana,and C. lasiocarpa all presented a pyramid form,with the leaf iron content at the top of pyramid being 3.08%,4.42%,and 1.18% of the sod layer(20-30 cm)iron content at the bottom of pyramid,respectively;while in early growth season(May),the profile of iron content fitted Logistic model well(R2=1.000,0.9902,and 0.9954,respectively). In the whole growth season,the iron content in the underground part of test wetland plants decreased gradually,while that in aboveground part changed with species and organs.
结果表明:3种湿地植物各器官的铁含量呈金字塔构型,成熟期（9月）时位于金字塔尖的叶的铁含量约为位于塔底的下草根层（地下2030cm）的3.08%、4.42%和1.18%;幼龄期（5月）的铁含量垂直剖面Logistic拟合很好,R2分别达1.0000、0.9902和0.9954;整个生长季地下部分铁含量均逐渐降低,而地上部分具有种间和器官间差异。
