In vitro regeneration of shoots from leaf explants of the Paradise tree (Melia azedarach L.) was studied. Three different portions (proximal portion, distal portion and rachis of the leaflets) of three developmental stages (folded, young still expanding and completely expanded) of leaves of 10-15 year old plants of seven genotypes were cultured on Murashige and Skoog (1962) medium (MS) suppleme...

Investigation on the fruits of Melia toosendan afforded seven new lignans (1-7), along with seventeen known compounds (8-24). The structures of the new compounds, involving four neo-lignans (1-4), two sesquilignans (5-6), and a nor-lignan (7), were elucidated based on extensive spectroscopic analyses (high-resolution electrospray ionization mass spectra, ultraviolet, infrared, one-dimensional a...

Melia azedarach L. is a native tree species that can be used in comprehensive way and widely distributed all provinces south of the Yellow River China. Genetic diversity analysis different M. germplasm sources an important basic work for selection, evaluation, genetic improvement resources. In this study, 100 pairs SSR primers were designed synthesized based on transcriptome data, 16 reliable f...

Cations leaching from leaf litter of Melia azedarach (Linn.) was studied in laboratory. About 37% initial dry weight lost after 72 hours. Conductivity and total dissolved solid (TDS) the leached water significantly (p<0.05) increased to 475 µS cm-1 227 mg l-1, respectively. pH dropped 5.64 at end experiment. TDS showed significant (p<0.05, r=0.99) positive linear relationships with loss l...

Biomass and carbon stock in a forested areas are now prime important indicators of forest management climate change mitigation measures. But the accurate estimation biomass trees forests is challenging issue. In most cases, pantropical regional models used frequently to estimate trees, but these estimations have some uncertainty compared species-specific allometric model. Acacia nilotica, Casua...

Wood is a magnificent natural resource that can be regarded as the single most important of future. Eucalyptus camaldulensis and Melia azedarach trees were introduced in Iraq planted ornamental at parks streets. A study branch wood was conducted order to identify its basic properties along different level tree highlight potential utilizations Duhok- Kurdistan Region Iraq. Specimens six three le...

background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...
