Effect of hydrogen cyanamide on the endogenous hormonal content of pea seedlings

Share |

  Hydrogen cyanamide (HC) has been acclimated to breach bud and berry cessation and to advance acclaim in several species, responses usually associated with the activity of bulb hormones. However, actual few studies accept abstinent autogenous hormones afterwards Cyanamide treatment. Therefore, pea (Pisum sativum L.) seedlings with two absolutely developed internodes aloft the aboriginal blade were sprayed with 0, 0.1 and 0.3% (v/v) HC.

  Autogenous absorption of indole-3-acetic acerbic (IAA), abscisic acerbic (ABA), zeatin/zeatin riboside and N6(Δ2-isopentenyl) adenine/ N6(Δ2-isopentenyl) adenosine were abstinent by radioimmunoassay 31 and 80 h afterwards HC treatment. A cogent access in ABA and cytokinin (CK) levels was empiric 31 h afterwards alleviative the plants with 0.3% HC.

  Small baleful spots were aswell noticed in this treatment, appropriately absolute a baneful aftereffect of this treatment. Additionally, at 80 h, a cogent access in IAA was begin for both HC concentrations applied. The activity of Cyanamide www.chemical-raw-material.com/Chemical-raw-material/Cyanamide/ aloft ABA, CKs and IAA autogenous levels is discussed.
