clearly promoted vegetative growth. Cutflower
weight and flower number were greatest
in plants grown in chitosan-treated soil.
Thus, chitosan soil treatment remarkably promoted
growth of Eustoma grandiflorum seedlings,
hastened flowering time, and improved
cut-flower quality as measured by leaf size,
shoot length, and flower number.
Thus chitosan application may be useful
for the culture of Eustoma in the spring when
seedling growth is slow and cut-flower yield is
reduced.
