The Fate of Maleic Hydrazide on Tobacco during Smoking

The effects of maleic hydrazide on growth control of perennial ryegrass (lolium perenne L.CV. yarandi)

Factors affecting the formation of gum by Alcaligenes faecalis.

Maleic hydrazide (1, 2-dihydropyridazine-3, 6dione) is an organic plant growth regulator which has found use in such varied areas as prevention of sucker formation in tobacco, prevention of sprouting of some stored vegetables, and as a herbicide. In commercial application the diethanolamine salt (diethanolammonium maleic hydrazide or diethanolammonium-1 ,2-dihydropyridazine-3, 6-dione) is often...

The Effects of Maleic Hydrazide on Flower Initiation.

Since the biological effects of maleic hydrazide (MH) were first described by SCHOENE and HOFFMANN (4), a great many papers have appeared describing the effects of that compound on growth and flowering. NAYLOR (3) sprayed tobacco, maize and cocklebur with various concentrations ranging from .025% to .2%o and obtained either suppression or delay of visible flowering. WHITE and KENNARD (5) delaye...

Differential genotoxicity of ethyl methanesulphonate, N-ethyl-N-nitrosourea and maleic hydrazide in tobacco seedlings based on data of the Comet assay and two recombination assays.

The purpose of this study was to determine if mutagen-induced DNA damage is correlated with the frequency of induced recombination events. The alkylating agents ethyl methanesulphonate (EMS) and N-ethyl-N-nitrosourea (ENU), and the plant growth regulator and herbicide maleic hydrazide (MH) were compared in tobacco seedlings for their ability to induce DNA damage measured by the Comet assay, and...

The subchronic toxic effects of plant growth promoters in mice

The aim of this study was conducted to subchronic toxic effects separate and combined using of maleic hydrazide and ethephon in female mice. Treatment group divided into 9 groups according to chemicals’ doses and compared with controls. Three separate maleic hydrazide doses (100-200-400 mg/kg/day, in feed) and ethephon (50-100-150 mg/kg/day, in water) were given alone and in combination during ...
