Results dry matter accumulation of aerial part and under ground part of a . dahurica showed “ s “ curve , dry matter of aerial part gradually increased from the end of july to the early october and got to the peak in mid - october , then gradually decreased ; dry matter of under ground portion increased slowly in earlier stage and became rapidly from the end of august to the end of september , then reduced 結果白芷地上和地下部分干物質積累呈“ s ”型曲線,地上部分干物質在7月底至10月初逐漸增加, 10月中旬達到高峰,隨后降低;地下部分干物質前期增加較慢, 8月底至9月底為快速增長期,隨后增加稍有減慢。

The anti - microbial activities of crude ethanol extract from aerial parts of sophora alopecuroides and its petroleum ether , chloroform , n - butanol and water fractions of sophora alopecuroides to pythium aphanidermatum , fusarium oxysporum f . sp . cucumerinum , fusarium oxysporum f . sp . lycopersici , alternaria solani , pseudomonas pachrymans and xanthomonas vesicatoria were tested by mycelial radial growth test and agar - well diffusion 本實驗采用帶毒平板菌絲生長法和瓊脂打孔藥劑擴散法測定了苦豆子地上部分乙醇粗提物及其石油醚、氯仿、正丁醇和水層的不同極性溶劑萃取物對瓜果腐霉、黃瓜枯萎病菌、番茄枯萎病菌、番茄早疫病菌、黃瓜角斑病菌和番茄瘡痂病菌的抗菌活性。

The contents of three valepotriates in v . officinalis also varied significantly different areas , samples from nanchuan of chongqing showing the highest . it is also showed that the contents of three valepotriates in underground part of valerians plants are higher than that in aerial part and the contents of three valepotriates in valeriana jatamansi herb and v . officinal is herb collected in september is highest . valepotriates of valeriana jatamansi were obtained using petroleum ether , with content of valtrate , didrovaltrate and acetovaltrate between 70 % and 80 % 我們以采用rp - hplc法測定不同產地、部位和采收期的纈草屬植物中纈草素、二氫纈草素和乙酰纈草素的含量,結果發現纈草類生藥蜘蛛香、纈草、寬葉纈草和黑水纈草之間纈草素類成分含量差異顯著,其中以蜘蛛香含量最高,纈草次之,寬葉纈草再次,黑水纈草含量最低。

In aerial parts of the plant the outer wall of the epidermis is usually covered by a waxy cuticle that prevents desiccation , protects the underlying cells from mechanical damage , and increases protection against fungi , bacteria , etc 植物地上部分的表皮的最外層通常覆蓋一層蠟質角質層,起保護作用以防止過渡蒸騰,并使下方的細胞免于機械損傷,同時增加對真菌、細菌等的防御能力。

Sonneratia ) that protrudes well above soil level the aerial part is covered with lenticels through which gases can diffuse to and from the highly developed system of intercellular airspaces 地上部分被有皮孔,氣體可以通過皮孔從細胞間隙的高度發達系統間進出。

The gmdreba , gmdrebb and gmdrebc genes were expressed at different level in aerial parts of soybean , but undetectable in root 基因gmdreba , gmdrebb和gmdrebc在大豆地上部分分別呈不同水平表達,而在根中檢測不到它們的表達。
