| 1 | 深圳市常见园林植物滞尘效应研究显示文摘以深圳市6种常见的园林植物为对象,研究其单位面积滞尘量及其粒径组成特征,探究植物叶片表面的微观形貌结构以及滞留颗粒物的组分和分布特征,分析气象因子对植物滞尘的影响。结果表明:1)6种园林植物的单位叶面积滞尘量排序为黄金榕(0.74±0.21 g/m2)>鹅掌藤(0.42±0.26 g/m2)>对叶榕(0.24±0.26 g/m2)>龙船花(0.20±0.07 g/m2)>沿阶草(0.18±0.10 g/m2)>鸡蛋花(0.15±0.10 g/m2);2)6种园林植物滞尘以粒径α>10μm的颗粒物为主,质量占比为59.21%~88.92%(黄金榕除外),鹅掌藤对α>10μm颗粒物的滞尘能力最强(0.34±0.20 g/m2),黄金榕对3μm<α<10μm(0.51±0.15 g/m2)和0.15μm<α<3μm(0.14±0.07 g/m2)颗粒物的滞留能力最强;3)6种园林植物叶表面的气孔、褶皱、沟槽、絮状凸起和绒毛等微观形貌有利于叶片对颗粒物的截留,叶片滞留颗粒物的元素组成主要为O,Si和Al;4)6种园林植物叶表滞留的大颗粒物(α>10μm)易受风速和温度的影响。研究结果对深圳市园林植物配置具有指导意义,并可为通过植物滞尘效应改善空气质量提供一定的理论依据。 | 殷卓君 沈小雪 李瑞利 高辉辉 于凌云 周琳 吴海轮 曹烨 | 2020 | 北京大学学报(自然科学版)2020，56，6： | 8 |
| 2 | 黄刺玫果提取物中几种化合物的含量测定显示文摘目的建立测量黄刺玫果中金丝桃苷、芦丁、槲皮素含量的方法,使其得到更好的开发应用。方法建立高效液相色谱方法,选择Inertsil-ODS-SP型号的色谱柱,乙腈(B)-0. 5%磷酸溶液(A)系统作为流动相,洗脱程序为:0-8 min,90%-81%A,10%-19%B; 8-12 min,81%-78%A,19%-22%B; 12-19 min,78%-76%A,22%-24%B; 19-28 min,76%-72%A,24%-28%B; 28-38 min,72%A,28%B; 38-45 min,72%-70%A,28%-30%B; 45-50 min,70%-90%A,30%-10%B; 50-55 min,90%A,10%B。从专属性、精密度、重复性、准确性、线性范围、系统适用性和加样回收率方面对该方法的科学性和可行性进行考察。结果芦丁、金丝桃苷、槲皮素的线性关系相关系数R2分别为0. 999 9,0. 999 9,0. 999 9,线性关系良好。芦丁、金丝桃苷和槲皮素的加样回收率分别为98. 10%,97. 50%和97. 80%。RSD值分别为3. 20%,2. 80%和3. 00%,符合实验要求。结论该方法可行性强,准确性、重复性均符合要求,线性关系良好,适用于测量乙酸乙酯萃取黄刺玫果提取物中芦丁、槲皮素、金丝桃苷的含量。 | 郝晓倩 王进东 卫罡 杨官娥 檀琪 | 2019 | 山西医科大学学报2019，50，5： | 8 |
| 3 | Effects of Particle Matters on Plant: A Review显示文摘The particle matter,particularly the suspended particle matter(PM≤2.5)in the air is not only a risk factor for human health,but also affects the survival and physiological features of plants.Plants show advantages in the adsorption of particle matter,while the factors,such as the leaf shape,leaf distribution density and leaf surface microstructure,such as grooves,folds,stomata,flocculent projections,micro-roughness,long fuzz,short pubescence,wax and secretory products,appeared to play an important role determing their absorption capacity.In this paper,the research progress on the capture or adsorption of atmospheric particles was summarized,and the forest vegetation and woody plants were discuessed.In addition,special attentions were paid to the effect of haze-fog weather on greenhouse plant,the different responses of plant leaves to dust particles and suspended particles,as well as the effect of suspended particles on morphological change of plants.In the future,research should focus on the mechanism of the influence of particulate matter on plants.More advanced effective and convenient research methods like spectral detection method also need to be developed.This paper may provide reference for future studies on plants’response to haze and particle matter. | Lijuan Kong Haiye Yu Meichen Chen Zhaojia Piao Jingmin Dang Yuanyuan Sui | 2019 | Phyton-International Journal of Experimental Botany2019，88，4： | 0 |
