The effects of indole-3-butyric acid and 6-benzyloaminopuryn on Fabaceae plants morphometrics
Sosnowski, Jacek | Krol, Justyna | Truba, Milena
The experiment was conducted to study the impact of indole-3-butyric acid (synthetic auxin) and 6-benzyloaminopuryn (synthetic cytokinin), and the mixture of these compounds on fresh and dry matter production and the number of leaves, stems, and inflorescences Medicago x varia T. Martyn and Trifolium pratense L. For the plants to be thoroughly covered, 0.2 dm³ of spraying liquid was used per one cylinder with growth regulator concentration of 30 mg dm⁻³. Synthetic auxin in the form of IBA, cytokinin in the form of BAP, and their mixture significantly affected biometric parameters of hybrid alfalfa and red clover. However, auxin was more effective than cytokinin. Plants treated with it had more leaves, stems, and inflorescences, which caused an increase in fresh and dry matter weight. Hybrid alfalfa produced more fresh and dry matter than red clover. Plants of the first harvest had the highest values of most biometric features.
