Abstract
Abstract Method of preserving and/or increasing the life of a cut flower, such as a rose, the stem of which is immersed in water includes placing the basal end of the the flower stem in a conduit or tube containing a water-porous, ion exchange resin mass and which is disposed between the stem''s basal end and the water. The water enters the basal end after passage through the resin mass. The ion exchange device reduces physiological blockage of the waterconducting tissue and aids in retention of fresh weight of the flower.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
75 words
In the method wherein the stem of a cut flower is immersed in water to preserve and/or increase the life of the cut flower, the improvement which comprises introducing the cut end of the flower stem into contact with water under conditions such that substantially all of the water enters the cut end only after passage through a mass of anion exchange resin or a mixed bed of anion exchange resin and cation exchange resin.
Claim 2
Dependent Claim
75 words
In the method wherein the stem of a cut flower is immersed in water to preserve and/or increase the life of the cut flower, the improvement which comprises introducing the cut end of the flower stem into contact with water under conditions such that substantially all of the water enters the cut end only after passage through a mass of anion exchange resin or a mixed bed of anion exchange resin and cation exchange resin.
Claim 3
Dependent Claim
19 words
Method according to claim 1, further comprising the step of mixing a sugar and a bactericide with the water.
Claim 4
Dependent Claim
62 words
Method of increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising the steps of: a. disposing a water-porous, anion exchange resin mass between the basal end of the stem and water such that water passes through the resin into the flower stem; and b. inhibiting the passage of water into the flower stem.
Claim 5
Dependent Claim
62 words
Method of increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising the steps of: a. disposing a water-porous, anion exchange resin mass between the basal end of the stem and water such that water passes through the resin into the flower stem; and b. inhibiting the passage of water into the flower stem.
Claim 6
Dependent Claim
92 words
Device useful in increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising a conduit having therein a mass of anion exchange resin or a mixed bed of anion exchange resin and cation exchange resin, at least one end of the conduit being adapted to receive flower stems of varying size, the conduit being disposable between the basal end of the flower stem and the water such that substantially all of the water enters the basal end only after passage through the resin mass.
Claim 7
Dependent Claim
92 words
Device useful in increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising a conduit having therein a mass of anion exchange resin or a mixed bed of anion exchange resin and cation exchange resin, at least one end of the conduit being adapted to receive flower stems of varying size, the conduit being disposable between the basal end of the flower stem and the water such that substantially all of the water enters the basal end only after passage through the resin mass.
Claim 8
Dependent Claim
109 words
Device useful in increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising: a. tube means open at both ends, one end being adapted to receive the basal end of the flower stem and the opposite end being disposable in water; b. a water-porous, anion exchange resin mass located within the tube means between the first open end and the opposite open end such that water must pass through the resin into the stem''s basal end; and c. at least a portion of the tube means being adapted to securely hold the stem''s basal end adjacent the anion exchange resin mass.
Claim 9
Dependent Claim
109 words
Device useful in increasing the life of and/or preserving a cut flower the stem of which is immersed in water, comprising: a. tube means open at both ends, one end being adapted to receive the basal end of the flower stem and the opposite end being disposable in water; b. a water-porous, anion exchange resin mass located within the tube means between the first open end and the opposite open end such that water must pass through the resin into the stem''s basal end; and c. at least a portion of the tube means being adapted to securely hold the stem''s basal end adjacent the anion exchange resin mass.
