摘要：
Sporophytic shoot primordia are initiated on gametophyte tissue of Equisetum arvense when cultured in a medium supplemented with cytokinin. The initiated shoots can develop on a cytokinin-free medium. Oryzalin, a dinitroaniline herbicide, inhibited the initiation and development of sporophytic shoots. But gametophytic growth with normal morphogenesis was not inhibited by oryzalin. These results suggest that some alteration induced by oryzalin is fatal to sporophytic, but not to gametophytic morphogenesis. Histological features in relation to the inhibition of sporophytic morphogenesis by oryzalin are discussed.
