Author Information Genelyn G. Madjos  from the Institute of the  Department of Biological Sciences, College of Science and Mathematics, Western Mindanao State University, Zamboanga City, Philippines Journal Name Journal of Biodiversity and Environmental Sciences | JBES Abstract Nickel miningposed a serious environmental problem due to run-offs and tailings. To address this, current techniques include excavation, chemical stabilization and soil flushing, but these methods are costly and impractical. One of the ecologically accepted treatments is phytoremediation. With the capacity of Centella asiatica (gotu kola) to thrive in moist soils with domestic effluents, this present study sought to evaluate its phytoremediation potential by employing an experimental design with three replicates of: (a

Medicinal herbs are reserves for natural resources of each country. Iran also are rich of medicinal plant species. More medicinal plants are wild and their seeds have low . The experimental was carried out based on factorial (6*2 design in three replication by using of six treatments including: Acid Gibberlic 250( 500, ppm and Potassium nitrate ( 1 % , 2 % ) and cold treatment 4C in laboratory of seed technology of gene bank in research Institute of forestry and range land on 2011-2012 .
The seed germination characteristics including :percent and speed of germination ,rootlet and shootlet length, root to shoot ratio, seed length, fresh weight ,vigour index and number of normal seedling were calculated. The analysis of variance showed that there were significance (P≤5%) differences between treatment population and interaction of treatment with populations .
Comparing of seed germination characteristics of two populations showed that population of Safarlo with provenance of east Azarbijan had higher seed germination characteristics than Arasbaran population. Comparing of osmo-priming technique and cold treatment with control showed that prime of seed samples with Acid Gibberlic 250ppm and 500ppm was caused to enhancement of seed germination and seed emergence characteristics and vigour for both two populations compare with control and other treatment.

Let’s get some knowledge about this research.  Abstract Coastal area of East Java Sea has long been threatened by industrial source pollution, mangrove conversion into shrimp culture, over fishing, destructive fishing, sedimentation, and coastal settlement. Heavy-metal is probably the most threat that directly influ
