ABSTRACT:
The present invention relates to a peptide of the formula: ##STR1## wherein both of R.sup.1 and R.sup.2 represent SO.sub.3 H, or either of R.sup.1 or R.sup.2 represents SO.sub.3 H and the rest represents H; Z represents an .alpha.-amino acid residue; X represents H or an acyl; and Y represents OH, C.sub.1-6 alkoxy or NH.sub.2, and to a plant growth promoter comprising the peptide.
