The effects of indole-3-butyric acid and 6-benzyloaminopuryn on Fabaceae plants morphometrics

Abstract

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 dm 3 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.

Enhancing Agricultural Sustainability through Microbial-Mediated Abiotic Stress Tolerance

“…Gibberellic acid regulates the seed germination process, promotes the breakdown of seed dormancy, induction of hydrolytic enzymes α-amylase and protease and stem elongation and leaf expansion 123 . Experimental data showed that when a combination of Indole-Butyric Acid (IBA) cytokinin and gibberellic acid is used as a biostimulant on the seed of Gossypium hirsutum L. plant causes an increase in the seedling emergence percentage, leaf area, height, as well as the growth of seedlings 124 . Indole acetic acid and gibberellic acid are well-studied bacterial and fungal signalling molecules that are produced during plantmicrobe interactions as Microbial Plant Biostimulants (MPB) to boost plant growth and tolerance to abiotic stresses 125,126 .…”
