USE OF A CYTOKININ TO PROMOTE GROWTH OF SHOOTS FROM A LOG
The present invention provides methods for promoting the growth of shoots from a log, wherein the methods each include the step of applying at least one cytokinin to a member of the group consisting of an Alder log, a Beech log and a Birch log, in an amount sufficient to promote the growth of shoots from the log.
1 . A method for promoting the growth of shoots from a log, the method comprising the step of applying at least one cytokinin to a member of the group consisting of an Alder log, a Beech log and a Birch log, in an amount sufficient to promote the growth of shoots from the log.
2 . The method of claim 1 , wherein the cytokinin is applied to the log as an aqueous solution.
3 . The method of claim 2 , wherein the aqueous solution is applied to the log as a mist.
4 . The method of claim 1 , wherein the cytokinin is continuously applied to the log.
5 . The method of claim 1 , wherein the cytokinin is intermittently applied to the log.
6 . The method of claim 1 , wherein the cytokinin is applied to the log at least once per week on each week of a series of successive weeks.
7 . The method of claim 1 , wherein the cytokinin is selected from the group consisting of benzylaminopurine, 6-furylfurylaminopurine, 6-(4-Hydroxy-3-methylbut-2-enylamino)purine, and 6-(γ,γ-Dimethylallylamino)purine.
8 . The method of claim 1 , wherein the cytokinin consists essentially of benzylaminopurine.
9 . The method of claim 2 , wherein the concentration of the cytokinin in the aqueous solution is from about 5 mg/L to about 100 mg/L.
10 . The method of claim 9 , wherein the cytokinin is selected from the group consisting of benzylaminopurine, 6-furylfurylaminopurine, and 6-(4-Hydroxy-3-methylbut-2-enylamino)purine.
11 . The method of claim 2 , wherein the concentration of the cytokinin in the aqueous solution is from about 0.5 mg/L to about 10 mg/L.
12 . The method of claim 11 , wherein the cytokinin consists essentially of 6-(γ,γ-Dimethylallylamino)purine.
13 . The method of claim 1 , wherein the cytokinin is benzylaminopurine present in an aqueous solution at a concentration in the range of from about 5 mg/L to about 100 mg/L, and the benzylaminopurine is applied to the log as a mist from once to three times per week for at least three weeks.
14 . The method of claim 1 , further comprising applying a fertilizer, that includes no more than about 0.01% (w/v) nitrogen, to the log in an amount sufficient to promote the growth of shoots from the log.
