[0030] A Screening Method for Efficient Manganese / Cadmium Absorption Ecological Pokeweed
[0031] Evaluation of Heavy Metal Pollution in Collection Areas of Wild Pokeweed Populations
[0032] Overview of collection areas: Sampling was carried out in 19 regions across the country from August to November 2014, and the heavy metal pollution in each region was investigated. The distribution of sampling points is as follows: 10 in Hunan, 3 in Guangxi, 3 in Jiangxi, and 1 in Zhejiang. and Jiangsu 2. During the sampling process, pokeweed leaves, seeds and corresponding surrounding soil were collected. (See Table 1 for details).
[0033] Sample collection method: In each sampling area, select 18 large pokeweed plants (over 2 years old), collect about 20 mature leaves each, and put them in a color-changing silica gel for sealed storage. Then collect the soil corresponding to the Pokeweed plant, use a shovel to select 5 points within a radius of 20cm around the root of Pokeweed to sa...
