Dissolving Benzylaminopurine

The textbooks indicate that NAOH is required to dissolve benzylaminopurine. But NAOH is not easy to prepare. Fortunately, a member of our user group has come up with an easier and better way to dissolve benzylaminopurine. Basically, we placed 1 scoop of benzylaminopurine in a small glass container with a small amount of 70% store-bought rubbing alcohol and a few drops of no-tear baby shampoo. This was kept heated between 110 and 150 Fahrenheit for a few minutes and the benzylaminopurine fully dissolved. If you can get alcohol that has higher purity then use that.

Important: if after a few minutes some of the benzylaminopurine has not dissolved you probably need to add more alcohol and shampoo.

Important: following some tests we found that some types of alcohol were more effective than others. 70% rubbing alcohol (Isopropyl) bought from any pharmacy was much more effective than even 99% methanol alcohol. While both dissolved the powder when it cooled down many flakes came back with the methanol alcohol and not with the rubbing alcohol.

Important: If you decide to use NAOH please remember that it will raise the PH level of the solution. It is a good idea to get a cheap PH test kit (Wardley Junior pH Water Test Kit, at less than $3.00) at places like Wal-Mart and to adjust the PH level if needed (Wardley PH UP at less than $4.00). Members of our user group reported that they had various problems doing things like getting cuttings to grow roots until they adjusted the PH of the water. What we found is that most tap water has a PH range that is to high for most plants. You can also find some very nice electronic PH meters on eBay for cheap.

Example

We put 3 scoops of benzylaminopurine and 3 spoons (about 25 ML, less than 1 ounce) of 70% rubbing alcohol in a small glass container (a small salt shaker) with a few drops of no-tear baby shampoo. It was heated up to around 140 F (around 60 Centigrade) and after nine minutes there was much less visible flakes than when we started. After a few more minutes all the flakes had dissolved.

Diluting Benzylaminopurine

Once the Benzylaminopurine has been dissolved (see above) you mix it in water to dilute it. How much water to use depends on what Parts-Per-Million (PPM) you will use. To decide on the best PPM please take a look at the research and information that is available. The best place to start would be the FAQ on this page.

Once your know what PPM your want look at the "Benzylaminopurine Mixing" table below to decide how much water to use. The table indicates how many scoops of powder to use with how much water. After dissolving add it to the water, do not add the water to it.

Using The Solution

The 0.47 liter was put in a spray bottle and the plant was sprayed until the solution was dripping from the plant. As a safety measure it is always a good idea to spray the plant outside if possible or in a closed separate room.

Benzylaminopurine Mixing Product Purity: 98.0%. Scoop weight: 0.03 grams. Fill the scoop to the top but not above the rim. Please read the FAQ and select the PPM that seems the best for you type of plant and the type of results you want. It may be smart to start at an even lower PPM and over time, depending on results, you can raise or lower the PPM.

1. What Is Benzylaminopurine?

Benzylaminopurine is a cytokinin that has a large array of effects. It speeds up cell growth and division, buds, flowering and branching.

2. What Are The Effects of Benzylaminopurine?

Benzylaminopurine has been found ¹ to increase the thickness of stems, increase the leaf surface and the number of side branches. At the same time root growth was slowed down. This is very likely because the larger leaves provide more nutrients to the plant and reduce the need for root mass. At higher concentrations of 300 to 400ppm stem elongation was reduced.

3. How Does 6-Benzylaminopurine Affect Apical Dominance And The Number of Branches?

Tests on different plant types have shown that Benzylaminopurine will increase the number of branches. The Ontario Hosta Society reports ¹ that wetting a hosta-leaf with 1000 PPM to 3000 PPM will cause the plant to branch out similar to cutting the end of the branch without the damage that pruning would cause. But one of our users has reported that while this is effective on younger hosta plant older plants do not always respond as well. Given this information I would recommend trying a lower dosage first before trying 3000 PPM.

A Plumeria Society Research Bulletin ² also reports that if a branch is pruned 6-Benzylaminopurine will generate more branches than prunning alone.

In another test ³ on Anthurium 'Ozake Red' plants ethephon, PBA and BA showed that the best results were 1000 PPM 6-Benzylaminopurine.

Another test ³ was conducted on Dieffenbachia with foliar applications of 500, 1000 and 2000 PPM of Benzylaminopurine. All treated plants averaged 6 lateral shoots while untreated plants at 2. At the same time plant height was unaffected by the Benzylaminopurine.

4. What Treatment Frequency Has Been Tested?

Tests on a nonbranching Dieffenbachia hybrid indicated ¹ that a foliar spray for three days in a row had more lateral shoot development than plants treated only once or even on two consecutive days. At the same time plants treated with 500 or 750 PPM had better results than 250 PPM. The new shoots were visible 4 weeks after treatment.
