We want to study the effect of exogenous ABA plant hormone treatment on pear fruit. A lot of journals mentioned the concentration needed but didn't provide technical protocols on how to prepare the solution for treatment.
Thank you very much for your kind attention
If you are using HPLC follow this method (PDF attached), or if any other spectroscopic analysis then check out this review, Article Progress in quantitative analysis of plant hormones
To prepare a 1 mg/ml stock solution: Add 100 mg of the plant growth regulator to a 100 ml volumetric flask or other glass container. Add 2-5 ml of solvent to dissolve the powder. Once completely dissolved, bring to volume with double processed water. Stirring the solution while adding water may be required to keep the material in solution. Store the stock solution as recommended. Add 1.0 ml of the stock solution to 1 liter of medium to obtain a final concentration of 1.0 mg/L of the plant growth regulator in the culture medium.

Dear Mr Muhammad Younas Mr Muhammad Nadeem and Mr Francisco X Nascimento
Thank you very much for your helps. Unfortunately, those are not the answer I seek. I am planning to use the solution on pear fruit by spraying method, directly on the fruit on the field. This is not for analysis but for exogenous application or treatment on plant organs.
I appreciate your help
Thank you very much
Best regard
Imad
