The bases of the cuttings were immersed for 10 min in solutions with different concentrations of the auxin IBA (1.5, 15, 150, and 1500 mg [L.sup.-1]), containing 100 mg [L.sup.-1] boron or zinc.
Significant increase in seedling vigour may result due to increased synthesis of auxins (Grobelak and Hiller, 2017).
There are many factors that may explain this hypothesis, such as the distribution and the hormonal balance in the propagative material used, especially because auxin is the main hormone associated with rooting in plants (GUAN et al., 2015; PACURAR et al., 2014).
Previous research has documented that synthetic auxins herbicides drift onto sensitive soybean can cause many negative effects, such as reduction of seed weight, lower seed quality, lower seed oil and protein concentration, pod malformation and impacts on progeny (ROBINSON et al., 2013a, 2013b; SOLOMON & BRADLEY, 2014; KESOJU et al., 2016; MILLER & NORSWORTH, 2017).
(2007) corroborate with this statement and argue that the benefits provided by diazotrophic bacteria are linked to the plant hormones production, such as auxins, gibberellins and cytokinins that are able to stimulate plant growth, especially roots.
Changes in the concentrations of auxins and polyamines during rooting of in vitro propagated walnut shoots.
Soybean, cotton (Gossypium hirsutum L.), and grain sorghum (Sorghum bicolor) are among the crop species most susceptible to synthetic auxin herbicides, such as dicamba, 2,4-D, and florpyrauxifen-benzyl.
All the leaves were removed from stem cuttings, and the cuttings were dipped in 0.1% bavistin (fungicide, BASF Ltd, Mumbai) solution (w/v) for 5 min subsequently washed with distilled water, and treated with root promoting auxins.
