Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
27 words
A method of increasing carotenoid content in plant tissue by applying to the said plant tissue an effective amount of 2-(p-chlorophenylthio)-triethylamine or an acid addition salt thereof.
Claim 2
Independent Claim
30 words
A method of increasing carotenoid content in plant tissue by applying to the said plant tissue an effective amount of an aqueous solution of an acid addition salt of 2-(p-chlorophenylthio)-triethylamine.
Claim 3
Independent Claim
45 words
A method of increasing carotenoid content in plant tissue by applying to the said plant tissue an effective amount of a composition consisting essentially of an aqueous emulsion of 2-(p-chlorophenylthio)-triethylamine, a solvent for the amine which is essentially insoluble in water, and an emulsifying agent.
Claim 4
Independent Claim
27 words
A method of increasing carotenoid content in fruit tissue by applying to the fruit an aqueous composition containing an effective amount of a compound of the formula:
Claim 5
Dependent Claim
19 words
The method of claim 5 wherein the pH is in the range of from about 6 to about 11.
Claim 6
Dependent Claim
11 words
The method of claim 5 wherein the pH is about 10.
Claim 7
Independent Claim
41 words
A method of increasing carotenoid content in fruit tissue by applying to the fruit an aqueous composition containing an effective amount of 2-(p-chlorophenylthio)-triethylamine or an acid addition salt thereof; wherein the said composition is at a pH greater than about 4.
Claim 8
Dependent Claim
19 words
The method of claim 8 wherein the pH is in the range of from about 6 to about 11.
Claim 9
Dependent Claim
11 words

Claim 11
Dependent Claim
19 words
The method of claim 11 wherein the pH is in the range of from about 6 to about 11.
Claim 12
Dependent Claim
11 words
The method of claim 11 wherein the pH is about 10.
Claim 13
Independent Claim
42 words
A method of increasing lycopene content in grapefruit by applying to the fruit an effective amount of 2-(p-chlorophenylthio)-triethylamine or an acid addition salt thereof; wherein the said 2-(p-chlorophenylthio)-triethylamine or its acid addition salt is at a pH of greater than about 4.
Claim 14
Dependent Claim
19 words

Claim 15
Dependent Claim
11 words
The method of claim 14 wherein the pH is about 10.
Claim 16
Independent Claim
50 words
A method of increasing carotenoid content in fruit tissue by applying to the fruit an effective amount of a composition consisting essentially of an aqueous solution of an acid addition salt of 2-(p-chlorophenylthio)-triethylamine and an alkaline monoteric surfactant; wherein the said composition is at a pH greater than about 4.
Claim 17
Independent Claim
57 words
A method of increasing carotenoid content in fruit tissue by applying to the fruit an effective amount of a composition consisting essentially of an aqueous emulsion of 2-(p-chlorophenylthio)-triethylamine, a solvent for the amine which is essentially insoluble in water, an emulsifying agent, and a base; wherein the said composition is at a pH greater than about 4.
Claim 18
Dependent Claim
10 words

Claim 19
Independent Claim
55 words
A method of increasing carotenoid content in fruit tissue by applying to the fruit an effective amount of a composition consisting essentially of a co-solvent aqueous solution of 2-(p-chlorophenylthio)-triethylamine, a solvent for the amine which is essentially soluble in water, and a base; wherein the said composition is at a pH greater than about 4.
Claim 20
Dependent Claim
11 words
The method of claim 20 wherein the solvent is hexylene glycol.
Claim 21
Dependent Claim
10 words
The method of claim 20 wherein the solvent is butoxyethanol.
