the allelopathic effect of weeds frequently inhibited the germination and seedling growth of crops. johnsongrass (sorghum halepens) is known to contain water-soluble substances that are allelopathic. to identify the allelopathic effect of johnsongrass, the effect of different aqueous extracts (0, 5, 10, 20, 30, 40 and 50 g l-1) obtained from roots and leaves of johnsongrass on the seed germinat...

background: the seeds of some medicinal plants and their compounds have long been valued for their numerous health benefits. objective:to investigate some physical and chemical properties of salvia spp. methods: some physico-chemical properties in five species of salvia seeds (consisted of s. officinalis l., s. macrosiphon l., s. hypoleuca l., s. sclarea l. and s. nemorosa l.) were measured at ...

The effect of ultrasound in combination heat on the extraction yield and technological properties chia seed mucilage was investigated. Chia seeds were mixed with distilled water at a seed-to-water ratio 1:30. dispersion adjusted to pH 9 treated either by bath or heat/ultrasound probe-type sonication 50 °C 80 for 30 60 min. samples evaluated. gave greater (6.92–10.52%) as compared (1.03–1.86%). ...

this experiment was carried out in experimental farm of agricultural faculty of ferdowsi university of mashhad, iran during 2010. the design was split plot with three replications. main plots were the medicinal plant species consist of: blond psyllium (plantago ovate forssk.), clasping peperweed (lepidium perfoilatum l.), qodumeh shirazi (alyssum homolocarpum l.) dragon's head (lalementia iberi...

Hydrocolloids were extracted from seed mucilage and the pulp fractions from red tamarillo (Solanum betaceum Cav.) mesocarp, and characterisation of their techno-functional properties and in vitro bile acid-binding capacities was performed. The seed mucilage hydrocolloids that were extracted, using either 1% citric acid (THC) or water (THW), had a good foaming capacity (32–36%), whereas the pulp...

Perfect timing of germination is required to encounter optimal conditions for plant survival and is the result of a complex interaction between molecular processes, seed characteristics, and environmental cues. To detangle these processes, we made use of natural genetic variation present in an Arabidopsis (Arabidopsis thaliana) Bayreuth × Shahdara recombinant inbred line population. For a detai...
