![]() (1999), who recommended leveraging the accumulation capability of hyperaccumulator plants to remove heavy metals from the soil which is a cost-effective, environmentally friendly, and sustainable method. The concept of phytoremediation was first introduced by Chaney et al. Therefore, cleanup of Cd-contaminated soil is increasingly imperative. Thus, it remains a possible health risk to humans due to bioaccumulation in the food chain, which can lead to lethal disorders like “itai-itai disease”. The results suggested that programme management should consider variation in seed germination traits when select which population could be applied to what kind of target remediation sites.Ĭadmium (Cd), produced by industrial activities such as mining, electroplating, and waste irrigation, is one of the most hazardous and ubiquitous contaminants in soil and water. Differences in seed germination among populations may be complicated, which could not be simply explained by the temperature and rainfall conditions where the seeds were produced as previously reported. pilosa on temperature and water differed significantly among populations. In addition, the median base water potential for germination of seeds from Danzhou population was higher than that for seeds from Baoshan and Guilin population at low temperatures (< 25 ☌), which was opposite at high temperatures (≥ 25 ☌). Seeds from Danzhou population displayed a higher base temperature ( T b) for germination than those from Guilin and Baoshan population, however the ceiling temperature ( T c) had no consistent level among the populations but varied according to the water potential. pilosa seeds were significantly by population, temperature, water potential and their interaction except for the interaction of population and water potential. The results showed that germination percentage and rate of B. Seeds of three populations were incubated at seven constant temperatures (8, 12, 15, 20, 25, 30, and 35 ☌) and at each of four water potentials (0, -0.3, -0.6, and -0.9 MPa). pilosa cypselae (the central type, hereafter seeds) from three populations using the thermal time, hydrotime, and hydrothermal time models. Present study was conducted to compare the requirements of temperature and water potential for germination of B. Understanding variability in seed germination among populations is crucial for determining which populations to use for soil remediation programs. pilosa have been documented, while the difference among populations remains unclear. Bidens pilosa L., an annual herb, has recently been shown to be a potential Cd-hyperaccumulating plant.
