Abstract
A phytohormone for inducing root hair curling and root nodulation in the roots of leguminous plants particularly in the absence of nitrogen-fixing bacteria. The phytohormone comprises a pentassaccharide having a fatty acid condensed on the non-reducing end. a method for treating the roots of leguminous plants for inducing root hair curling and root nodulation is also disclosed.
Claims6
A phytohormone for inducing root hair curling and root nodulation in the roots of leguminous plants, wherein said hormone is a pentasaccharide having the structure:
- ##STR2## wherein R is selected from the group consisting of (CH.sub.2).sub.15 CH.sub.3 and (CH.sub.2).sub.n --CH.dbd.CH--(CH.sub.2).sub.m --CH.sub.3, wherein n+m is 13 or 15 and R' is selected from the group consisting of H and CH.sub.3 CH.sub.2 C.dbd.0.
A method for treating the roots of leguminous plants for inducing root hair curling and root nodulation, said method comprising treating the roots of the plants with a pentasaccharide having the structure:
- ##STR3## wherein R is selected from the group (CH.sub.2).sub.15 CH.sub.3 and (CH.sub.2).sub.n --CH.dbd.CH--(CH.sub.2).sub.m --CH.sub.3, wherein n+m is 13 or 15 and R' is selected from the group consisting of H and CH.sub.3 CH.sub.2 C.dbd.0.
