Dose-Response Analysis of Factors Involved in Germination and Secondary Dormancy of Seeds of Sisymbrium officinale: I. Phytochrome.
The germination of seeds of Sisymbrium officinale is light- and nitrate dependent. A close interaction between the effects of light and nitrate on germination has been reported previously (HWM Hilhorst, CM Karssen [1988] Plant Physiol 86: 591-597). In this study, a detailed dose-response analysis of the light-induced germination during induction of secondary dormancy is presented. Germination i...
متن کاملDifferent approaches to study the traditional remedy of ‘hierba del canto’, Sisymbrium officinale (L.) Scop
The infusion of the semi-fresh flowering aerial parts of Sisymbrium officinale (L.) Scop. (Brassicaceae), commonly known as hierba del canto in Spanish, is a popular remedy for the treatment of sore throats, coughs, and hoarseness, but little is known about its chemistry and pharmacology. HPLC-UV/PDA analyses of the dichloromethane and methanol extracts of both the fresh and the dried plant mat...
متن کاملPhysical forces in dormancy and germination of xanthium seeds.
The germination of seeds of Xanthium pensylvanicum Wallr. occurs in 2 phases, an initial passive phase of water uptake followed by an active phase of growth. These 2 phases have been separated experimentally, and shown to occur similarly in isolated cotyledons and embryonic axes. Measurements of the physical thrust generated by the entire seed and its separate components of cotyledon and axis r...
متن کاملDormancy and Seed Germination in Tamarindus indica (L)
The dormancy and seed germination of Tamarindus indica (L) was studied. This involved the usage of some dormancy-releasing methods and the influence of oven dry heat treatments on the seeds. The preliminary germination tests on fresh and air-dried seeds showed low percentage germinability (10-20%). The seeds are known to have high socio-economic value most especially in the savanna regions of t...
متن کاملGermination of Barley as Affected by the Allelopathy of Sisymbrium irio L. and Descurainiasophia (L.) Schur
An experiment was conducted under controlled conditions to study the effect of water extract of leaves, shoots and roots of either Sisymbrium irio L. =SISIR and or Descurainia sophia (L.) Schur =DESSO on the germination and primary growth of barley. A split-split plot experiment in CRD with three replications was used. The main plots were the type of weed: i.e. SISIR and DESSO and the sub-plots...
