Hot water treatment is also used for removal of pathogens. Placing seeds in 90 °C for 90 seconds followed by dip in cold water for 30 seconds kills the human pathogens Escherichia coli O157:H7 and Salmonella.[2] A variety of plant pathogens are also killed by hot water treatment.[3]
Okpomọkụ
dezieIn some chaparral plant communities, some species' seeds require fire and/or smoke to achieve germination. An exception to that phenomenon is western poison oak, whose thick seed coatings provide a time delayed effect for germination, but do not require fire scarification.[4]
