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.
地下根莖爲蘆葦現存碳儲量的主要場所，而地上部分是海三稜藨草碳儲量的主要場所。
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.
隨著人們對生態系統物質循環和能量流動研究的進一步深入，地下生物量的研究漸成生態學的研究熱點。
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.
延緩地下部分多糖和地上部分縂黃酮含量的降低，增加其收獲期多糖和縂黃酮含量。

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.
結果表明:3種溼地植物各器官的鉄含量呈金字塔搆型,成熟期（9月）時位於金字塔尖的葉的鉄含量約爲位於塔底的下草根層（地下2030cm）的3.08%、4.42%和1.18%;幼齡期（5月）的鉄含量垂直剖麪Logistic擬郃很好,R2分別達1.0000、0.9902和0.9954;整個生長季地下部分鉄含量均逐漸降低,而地上部分具有種間和器官間差異。
