This work focuses primarily on the comparative response of rat liver enzymes to oral administration of the watersoluble fraction of 95% ethanol extract of Nauclea latifolia Sm. (Rubiaceae) leaves with 10% coconut oil meal and normal rat chow fed for 8 weeks. Forty-eight mature male albino rats of the Wistar strain weighing between 200 and 230 g were divided into two experimental groups. In expe...

It has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...

Stem length and leaf area of current-year shoots were measured in saplings of eight broad-leaved evergreen tree species growing under a forest canopy. Stem length varied over a range of one to two orders of magnitude within each species. In all species, both the number of leaves and the mean stem length between successive leaves were greater in longer shoots. Mean leaf size and stem length were...

greenhouse and laboratory studies were conducted to examine the allelopathic effects of water extracts of pigweed (amaranthus retroflexu l.) leaf, stem, root and flower at different growth stages on canola seed germination and seedling growth. water extracts of leaf, stem, root and flower as individually, binary, ternary and quadri mixtures at 0, 50 and 100% concentrations were made and their e...

in this research, possibility of bulblet production from different cuttings including leaf, leaf-bud and leafy-stem of lilium oriental hybrid cv. ‘star gazer’ evaluated under different levels of indole-3-butyric acid (iba) with 0, 250, 500, 750 and 1000 mg per liter (ppm). the cuttings were taken from stems which grown from cold treated bulbs in early october. a factorial experiment was done in...

Nowadays, many researches were conducted in minimizing tissue culture technology due to the overhead of cost needed. The purpose of this study was to investigate the effects of using five kinds of organic additives at four level concentrations responsive to the number of shoots produced for eight weeks in culture. Stem segment explants of Celosia sp. were cultured on MS medium that have been su...

The essential oils obtained by hydrodistillation from the stem, leaf and flower of Phlomis aucheri Boiss., which is endemic to Iran, stem, leaf and root of Teucrium polium L. and solvent free microwave extraction oil from leaf of Ajuga chamaecistus Ging. subsp. chamaecistus were analyzed by GC and GC/MS. Germacrene D (11.1%, 28.3% and 21.1%) was the main constituent in the stem, leaf and flower...

Cattleya trianae is an endemic species from the tropical rainforest in the Colombian Andes. Its survival is currently threatened due to habitat loss and commercial overexploitation. This study evaluates ten substrates, some organic (pine bark, coconut fiber and wood shavings), some inert icopor (polystyrene foam), vegetable coal and their combinations, and the effects these have on morphometric...
