Abstract
|
|
|
|
Growth responses of lettuce seeds germinated in aqueous solutions of SO_2 were investigated for mode of action studies of this gas. The concentration and pH of SO_2 solution greatly affected the growth of germinating seeds. Root growth was more sensitive to SO_2 than hypocotyl growth. The sensitivity of total seedling growth lay between root and hypocotyl growth. Growth inhibition of germinating seeds appeared more serious when SO_2 was added during the early stage of germination.
