Ten maize lines prevalently used by breeders in the maize program were screened for their ability to form type II callus. Mature seeds were used as explant for in vitro culturing. Inbred lines showed high embryogenic response and formed friable, type II calli. And also exhibited successful plant regeneration. Various culture media compositions based on Murashige and Skoog (1962) salts thus inve...

Cecropia is a relatively well-known and well-studied genus in the Neotropics. Methods for the successful propagation of C. obtusifolia Bertoloni, 1840 from cuttings and air layering are described, and the results of an experiment to test the effect of two auxins, naphthalene acetic acid (NAA) and indole butyric acid (IBA), on adventitious root production in cuttings are presented. In general, C...

Soil proteases are involved in organic matter transformation processes and, thus, influence ecosystem nutrient turnovers. Phytohormones, similarly to proteases, synthesized and secreted into soil by fungi microorganisms, regulate plant rhizosphere activity. The aim of this study was determine the effect auxins, cytokinins, ethephon, chlorocholine chloride on spruce forest floor protease It conc...

With a very diverse structure and small molecules, phytohormones are regulators of plant growth development. Despite the fact that they synthesized by plants in quantities, highly active physiologically. According to their action, can be divided into two categories, as either activators development or inhibitors, with auxins cytokinins belonging former group. Auxins apical meristems shoots, but...

Pot experiments were conducted in a greenhouse of the National Technological Mexico Celaya during two summer seasons, 2019 and 2020, to study changes concentration nutraceutical compounds jalapeño chili pepper response phytohormones (gibberellic acid auxins) drying processes (lyophilization by convection oven). Jalapeño (Capsicum annuum L.) plants treated with separately acid, 5 mM solution aux...
