Abstract

Abstract Grasses of the non-stoloniferous type are vegetatively reproduced by treating the grasses with a growth regulator which produces aerial nodes in the stems thereof by internode elongation in the crown of the grasses. At least one of the aerial nodes are clipped from the stem and this clipping is sprigged into soil. The nodes on this clipping will root and produce tillers. In most instances, the nodes in the crown of the parent plant will produce tillers after removal of the clipping and thus the parent plant will also survive.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 32 words
The process of claim 1 in which the growth regulator is selected from the group consisting of 2-chloroethylphosphonic acid and its ethylene-producing derivatives, ethylene, gibberellic acid, 3,6-endoxohexahydrophthalic acid, 1-naphthaleneacetamide and mixtures thereof.
Claim 2
Dependent Claim 32 words
The process of claim 1 in which the grass is selected from the group consisting of Kentucky bluegrass, meadow fescue, tall fescue, perennial ryegrass, sudangrass, bromegrass, timothy, red fescue, bahiagrass and orchardgrass.
Claim 3
Dependent Claim 13 words
The process of claim 2 in which the growth regulator is 2-chloroethylphosphonic acid.
Claim 4
Dependent Claim 12 words
The process of claim 3 in which the grass is Kentucky bluegrass.
Claim 5
Dependent Claim 13 words
The process of claim 2 in which the growth regulator is gibberellic acid.
Claim 6
Dependent Claim 12 words
The process of claim 2 in which the growth regulator is ethylene.
Claim 7
Dependent Claim 13 words
The process of claim 2 in which the growth regulator is 3,6-endoxohexahydrophthalic acid.
Claim 8
Dependent Claim 12 words
The process of claim 2 in which the growth regulator is 1-naphthaleneacetamide.
Claim 9
Dependent Claim 16 words
The process of claim 4 in which the growth regulator is applied as an aqueous solution.
Claim 10
Dependent Claim 24 words
The process of claim 4 in which the solution contains from about 80 to 135,000 parts of growth regulator per million parts of water.
Claim 11
Dependent Claim 99 words
A process for vegetatively reproducing Kentucky bluegrass from vegetative stems comprising treating a first area of said bluegrass with a growth regulator selected from the group consisting of 2-chloroethylphosphonic acid, its ethylene-producing derivatives and mixtures thereof to produce aerial nodes in said stems by internode elongation between successive nodes in the crown of said grass, clipping at least one of said nodes from said stems and sprigging said clipping into a second area of soil, said regulator being applied in an amount sufficient to stimulate the production of aerial nodes, but insufficient to kill said first area of bluegrass.
Claim 12
Dependent Claim 13 words
The process of claim 12 in which the growth regulator is 2-chloroethylphosphonic acid.
Claim 13
Dependent Claim 26 words
The process of claim 12 in which the second area of soil is from five to thirty times larger than the first area of Kentucky bluegrass.
Claim 14
Dependent Claim 20 words
The process of claim 12 in which the bluegrass is treated with from 1 to 64 lbs/acre of growth regulator.
