taxus chinensis var. mairei is a rare and endangered medicinal plant species distributed in china. in order to promote fast propagation and preserve the natural resources, conditions for in vitro germination and seedling development of embryos of t. chinensis var. mairei from anhui or zhejiang were investigated. results showed that in vitro germination rate of excised embryos cultured under 14 ...

A total of 280 unsexed broiler chicks, 21 days-old and weighing 580 g on average were randomly distributed into 28 experimental units of 10 birds each. Seven experimental diets containing respectively 0% (T0 control), 20% raw cowpeas (T1), 20% raw cowpeas + 0.2% of Canarium charcoal (T2), 20% raw cowpeas + 0.2% maize cob charcoal (T3), 20% cooked cowpeas (T4), 20% cooked cowpeas + 0.2% Canarium...

Tylecodon ventricosus induced severe respiratory distress in two penned sheep without any electrocardiographic abnormalities being recorded. Based on the results it appears as if T. ventricosus predominantly induces the neuromuscular syndrome referred to as krimpsiekte. A single, relatively large intraruminal dose of 10.0 g/kg induced krimpsiekte in one sheep. Treatment with 5.0 g/kg activated ...

Single-dose activated charcoal therapy involves the oral administration or instillation by nasogastric tube of an aqueous preparation of activated charcoal after the ingestion of a poison. Volunteer studies demonstrate that the effectiveness of activated charcoal decreases with time. Data using at least 50 g of activated charcoal, showed a mean reduction in absorption of 47.3%, 40.07%, 16.5% an...

Cyperus scariosus R.Br is a valuable multipurpose medicinal herb, which belongs to family Cyperaceae. It possesses astringent, anti-inflammatory, diaphoretic, diuretic, cordial and stomach ache properties. An attempt has been made to study in vitro regeneration, floral bud induction, multiple shooting and multiple rooting has been achieved via healthy, moderate axillary buds as explants. The ax...

Changes in nucleotides and ribonucleic acids (RNA) in 'Valencia' orange have been determined as influenced by storage, ethylene, heat and commercial concentrating practices. All treatments tended to lower polymeric RNA species. Patterns of interactions in the case of nucleotides were evident and distinct for certain treatments. Changes in nucleotides may be related to the quality of the process...

Stabilized shoot cultures initiated from crown material of six adult Quercus robur L. trees and from basal epicormic shoots of a Quercus rubra L. tree showed good in vitro rooting capacity. An initial five-day dark period generally improved the rooting response but was detrimental to plantlet quality. There were clonal differences in rooting capacity. The concentration and exposure time of the ...

The authors evaluated the effectiveness of ReJeX-iT@ AG-145, Mesurola, activated charcoal, lime, and fipronil to reduce homed lark damage to lettuce seeds and seedlings. In Experiment 1, homed larks consumed significantly more feed mixture (50:50 grains and lettuce seed) than untreated clay-coated lettuce seed in a three-day choice-test. In Experiment 2, where clay-coated lettuce seed was treat...

Macrophomina phaseolina (Tassi) Goid., a pycnidia-producing fungus, is one of the most important soilborne pathogens, infecting over 500 plant species in more than 100 plant families around the world (1,18). It causes a major disease of soybean (Glycine max (L.) Merr.) called charcoal rot (18). Symptoms on soybean include blight of emerging seedlings, wilting, early maturation, and incomplete p...

Phytoliths can occlude some organic carbon during their deposition in plants. This carbon fraction is recognised as an ideal dating material because of its high resistance to decomposition and post-deposition contamination at the time of phytolith formation. However, the reliability of phytolith radiocarbon dating has recently been questioned. The development of a new extraction protocol for ph...
