Abstract：
Nano solutions are widely used in medicine and also have the potential to be used when performing allelopathy screening studies. The present experiment aimed to test the effectiveness of colloidal nano silver Silver-Amber© with nanoparticles of 20 nm (>20 mg/L at a purity level of 99.99%) as a carrier of allelochemicals in laboratory conditions. The influence of eleven concentrations of Silver-Amber© (0.10, 0.20, 0.39, 0.78, 1.56, 3.13, 6.25, 12.5, 25.0, 50.0 and 100.0% v/v) on the germination and initial development of test plant Lactuca sativa L. in 0.75% agar medium was studied. Data revealed that when increasing the quantitative ratio of Silver-Amber©, an inhibitory effect on seed germination (from 37.8 to 94.3%) and on the plant growth (from 54.0 to 98.9%) appeared. Lower concentrations (0.63 to 0.04 ppm) had an indifferent to statistically unproven stimulatory effect on the germination and initial development of L. sativa (GI ranged from 88.7-94.6%). Therefore, nano silver can be used as carrier of allelochemicals in allelopathic studies in laboratory conditions.
摘要：
纳米溶液广泛用于医学，并且在进行化感作用筛选研究时也有可能使用。本实验旨在测试具有20nm纳米颗粒(在99.99%的纯度水平下>20mg/L)的胶体纳米银-琥珀®在实验室条件下作为化感化学品载体的有效性。11种浓度的银琥珀©（0.10、0.20、0.39、0.78、1.56、3.13、6.25、12.5、25.0、50.0和100.0％v/v）对测试植物LactucasativaL.在0.75％琼脂培养基中研究了L.数据显示，当增加银琥珀的定量比时，对种子萌发的抑制作用（从37.8％到94.3％）和对植物生长的抑制作用（从54.0％到98.9％）出现。较低的浓度（0.63至0.04ppm）对紫花苜蓿的发芽和初始发育具有统计学上未经证实的刺激作用（GI范围为88.7-94.6％）。因此,纳米银可作为化感物质的载体在实验室条件下进行化感研究。
