evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

Secondary metabolites obtained from the indigenous plants with proven mosquito control potential can be used as an alternative to synthetic insecticides under the integrated vector control. The essential oil extract from the forest redgum, Eucalyptus tereticornis Sm. (Myrtaceae) was tested against mature and immature mosquito vector Anopheles stephensi Liston (Diptera) under laboratory conditio...

this study was carried out to evaluate the in vitro and in vivo antifungal efficacy of essential oil and extracts derived from the flower and leaves of magnolia liliflora, respectively, against plant pathogenic fungi. the oil (750 μg disc-1) and various leaf extracts such as hexane, chloroform, ethyl acetate and methanol (1,500 μg disc-1) revealed promising antifungal effects against botrytis c...

Khus-Khus (Vetiveria zizanoides Nash.) plants slips of 12.5-15 cms. length, were raised in contoled glass house conditions in different 0 –0. 5 and 1.0 Zn mg/l applications. Total monoterpene oil(s) maximum (0.21 %) was obtained at 0.250 Zn mg/l application at 4-5 inner one circumferential position of roots. At middle 4 th. position of leaf, net photosynthetic rate, and contents of chlorophyll ...

BACKGROUND Recently, essential oils and extracts derived from plants have received much interest as potential bio-active agents against mosquito vectors. METHODS The essential oils extract from fresh peel of ripe fruit of Citrus aurantium and Citrus paradisi were tested against mosquito vector Anopheles stephensi (Diptera: Culicidae) under laboratory condition. Then chemical composition of th...

While consumers are interested in organic or biorational alternatives to synthetic fungicides for the control of diseases of ornamentals as well as vegetables and tree fruits in residential landscapes, relatively few field trials have been conducted to establish their performance against ornamentals diseases. Weekly applications of Armicarb® 100 (potassium bicarbonate) controlled powdery mildew...

The aim of this study was to investigate the chemical composition and anticancer effect of the leaf essential oil of Xylopia frutescens in experimental models. The chemical composition of the essential oil was analysed by GC/FID and GC/MS. In vitro cytotoxic activity of the essential oil was determined on cultured tumour cells. In vivo antitumour activity was assessed in Sarcoma 180-bearing mic...
