Eight different compounds inspired by benzoxazinones were synthesized in one simple step with easy purification. These have a sulfur atom instead of the oxygen present benzoxazinones. Furthermore, new derivative obtained Rutkauskas–Beresnevicius reaction was synthesized. evaluated vitro to assess their phytotoxicity plant cells elongation wheat coleoptiles. The novel showed higher inhibition th...

Investigations were carried out with maize (Zea mays L.) seedlings. The effect of chlorsulfuron (CHF) on the electrophoretic profiles of the total and thermostable proteins, polypeptides and some antioxidant enzymes was compared to the effect of abscisic acid (ABA), benzylaminopurine (BAP) and N1-(2-chloro-4-pyridyl)-N2-phenylurea (4PU-30) applied in concentrations that inhibit the growth of se...

In studies of the bioelectric fields of the onion root, ROSENE (2) found that the magnitude of the longitudinal polarity was decreased or shunted when a jacket of tap water was placed around a segment of the root between the contacts. When the shunt was removed, the polarity quickly returned to practically its former level. Similar results were obtained by WnKs and LUND (7) from their experimen...

Auxins, mainly indole-3-acetic acid (IAA), play a critical role in numerous plant growth processes, including embryo development, root and flower development, vascular differentiation, stem elongation, apical dominance, and tropic responses. Charles Darwin and his son Francis performed some of the earliest work relating to the effect of auxin on plant growth with their experiments on phototropi...

The physical bases for enhancement of growth rates induced by auxin involve changes in cell wall structure. Changes in the chemical composition of the primary walls during maize (Zea mays L. cv WF9 x Bear 38) coleoptile development were examined to provide a framework to study the nature of auxin action. This report documents that the primary walls of maize cells vary markedly depending on deve...
