Substance introduction method for plant and plant obtained therewith

Abstract

This invention relates to a method for introducing a substance into a plant, said method comprising the following steps: forming a final hole into a stem of the plant, wherein the final hole is accessible via an opening in an outer surface of the stem, and wherein the final hole has a dimension in a direction parallel to a longitudinal axis of the stem which is larger than a maximum dimension of the opening in said direction parallel to the longitudinal axis of the stem subjecting the interior of the final hole to the substance by introducing the substance through the opening. The invention further relates to a plant provided with a hole into its stem, wherein the hole is accessible via an opening in an outer surface of the stem, and wherein the hole has a dimension in a direction parallel to a longitudinal axis of the stem which is larger than a maximum dimension of the opening in the direction parallel to the longitudinal axis of the stem.

1 . A method for introducing a substance into a plant, in particular a pot plant, the method comprising the following steps:
 forming a final hole into a stem of the plant, wherein the final hole is accessible via an opening in an outer surface of the stem, and wherein the final hole has a dimension in a direction parallel to a longitudinal axis of the stem which is larger than a maximum dimension of the opening in said direction parallel to the longitudinal axis of the stem; and   subjecting the interior of the final hole to the substance by introducing the substance through the opening.   
     
     
         2 . The method according to  claim 1 , wherein the step of forming the final hole further comprises the steps of
 forming an initial hole with corresponding opening in the stem of the plant; and subsequently extending a size of the initial hole through the already made opening in the stem of the plant.   
     
     
         3 . The method according to  claim 1 , wherein the step of forming the final hole comprises one or more of the following operations: drilling, cutting, suction, vaporizing, chemical etching and piercing. 
     
     
         4 . The method according to  claim 2 , wherein the initial hole is formed by inserting a tool into the stem in a direction perpendicular to a longitudinal axis of the stem, and wherein the size of the initial hole is extended by introducing a tool through the opening in the stem in a direction making an acute angle with the longitudinal axis of the stem. 
     
     
         5 . The method according to  claim 2 , wherein the size of the initial hole is extended at least in a direction away from the roots of the plant. 
     
     
         6 . The method according to  claim 2 , wherein the size of the initial hole is also extended in a direction towards the roots of the plant. 
     
     
         7 . The method according to  claim 2 , wherein the step of forming the initial hole comprises inserting a hypodermic needle with a beveled tip into the stem and subsequently rotating the hypodermic needle about a longitudinal axis thereof, wherein during these steps the longitudinal axis of the needle is perpendicular to a longitudinal axis of the stem. 
     
     
         8 . The method according to  claim 2 , wherein the step of extending the size of the initial hole comprises inserting a hypodermic needle with a beveled tip through the opening into the stem and subsequently rotating the needle about a longitudinal axis thereof, and wherein during these steps the longitudinal axis of the needle makes an acute angle with respect to a longitudinal axis of the stem at an angle between 30-60 degrees. 
     
     
         9 . The method according to  claim 2 , wherein extending the size of the initial hole further comprises the steps of:
 introducing an instrument or tool provided with cutters into the initial hole via the opening;
 extending said cutters in a direction parallel to the longitudinal direction of the stem of the plant; 
   retracting the cutters; and   withdrawing the instrument or tool from the hole.   
     
     
         10 . The method according to  claim 1 , wherein the step of forming the final hole comprises removing plant tissue from the stem of the plant. 
     
     
         11 . A plant, in particular a pot plant, provided with a hole into its stem, wherein the hole is accessible via an opening in an outer surface of the stem, and wherein the hole has a dimension in a direction parallel to a longitudinal axis of the stem which is larger than a maximum dimension of the opening in the direction parallel to the longitudinal axis of the stem. 
     
     
         12 . The plant according to  claim 11 , wherein seen in the longitudinal direction of the stem of the plant, the hole extends at least in a direction away from the roots of the plant. 
     
     
         13 . The plant according to  claim 12 , wherein the hole also extends in a direction towards the roots of the plant. 
     
     
         14 . The plant according to  claim 11 , wherein the interior wall of the hole is covered with a layer of material preventing the interior wall from drying. 
     
     
         15 . The plant according to  claim 11 , wherein the final hole is filled with wax to close off the opening in the outer surface of the stem. 
     
     
         16 . The method according to  claim 2 , wherein extending the size of the initial hole comprises inserting a hypodermic needle with a beveled tip through the opening into the stem and subsequently rotating the needle about a longitudinal axis thereof, and wherein during these steps the longitudinal axis of the needle makes an angle with respect to a longitudinal axis of the stem of 45 degrees. 
     
     
         17 . The method according to  claim 1 , wherein the step of forming the final hole comprises removing plant tissue from the stem of the plant during the formation of an initial hole and additionally or alternatively during extending the size of the initial hole.
