The effects of chitosan treatment on plant growth and flower quality of Eustoma grandiflorum (Raf.) Shinn. were investigated. The application of a soil mix of chitosan (1%, w/w) at sowing time remarkably enhanced growth, whereas coating seed with 0.1% chitosan in lactate was ineffective. Plants grown in the chitosan-treated soil flowered 15 days earlier than did control plants, and the number and weight of cut flowers produced were greater than for control plants or plants from chitosan-treated seed.
