germination stage is an important stage of plant growth stage that often is affected by environmental stress including water and salinity stresses including drought and salinity. in order to study germination characteristics of scrophularia striatain water and salinity stress conditions at different temperatures an experiment was conducted. temperatures regimes included 5, 10, 15, 20, 25, 30 an...

Objective: Use of plant based drugs and chemicals for curing various ailments and personal adornment is as old as human civilization. Plants and plant-based medicaments are the basis of many of the modern pharmaceuticals we use today for our various ailments. The present paper deals with the phytochemical screening of medicinally important compounds from Nigella sativa, an important medicinal p...

The distribution and dynamics of plant populations depend on the recruitment of young individuals, which is influenced by seed production, animal seed dispersal, dispersal distance, and the deposition of seeds in favourable places for seed germination/ establishment and seedling survival. In particular, seeds dispersed over long distances will likely encounter new environmental conditions that ...

Does Carpobrotus edulis have an impact on native plants? How do C. edulis' soil residual effects affect the maintenance of native populations? What is the extent of interspecific competition in its invasion process? In order to answer those questions, we established pure and mixed cultures of native species and C. edulis on soil collected from invaded and native areas of Mediterranean coastal d...

Seed heteromorphism is a common characteristic of halophyte and an adaptation to the spatial and temporal variations of natural habitats. Differences in dormancy and germination requirements have been documented in heteromorphic seeds of many species, but the mechanisms for maintenance between different status in various populations have not been well-understood. Salsola ferganica is a typical ...

Dispersal is a key process in metapopulation dynamics as it conditions species' spatial responses to gradients of abiotic and biotic conditions and triggers individual and gene flows. In the numerous plants that are dispersed through seed consumption by herbivores (endozoochory), the distance and effectiveness of dispersal is determined by the combined effects of seed retention time in the vect...

Rabea E.I., Steurbaut W. (2010): Chemically modified chitosans as antimicrobial agents against some plant pathogenic bacteria and fungi. Plant Protect. Sci., 46: 149–158. The antimicrobial activity of eight chemically modified chitosans against plant pathogenic bacteria of crown gall disease agrobacterium tumefaciens and soft mould disease Erwinia carotovora and fungi of early blight disease al...

A doubled haploid (DH) population of barley (Hordeum vulgare L.) generated from salinity tolerant genotype CM72 and salinity sensitive variety Gairdner was studied for salinity stress tolerance at germination, seedling emergence and first leaf full expansion growth stages. Germination study was conducted with deionized water, 150 mM and 300 mM NaCl treatments. Seedling stage salinity tolerance ...

This experiment was carried out during the two growing seasons 2012/2013 and 2013/2014 at the experimental farm of Unit for Strawberry and Non Traditional Horticulture Crops, Horticulture Department, Faculty of Agriculture, Ain Shams University, Egypt, in order to investigate the effect of magnetic field on germination of true potato seeds (TPS), vegetative growth and potato tubers characterist...
