Two Zea mays cultivars, salt sensitive Trihybrid 321 and salt tolerant Giza 2, were studied, namely their adaptation to NaCl imposition at cell and whole plant level. Changes in growth and mineral content of roots and shoots, glycinebetaine (GB) and free proline (Pro) levels of shoots, plasma membrane permeability and solute potential (ø s) of leaf sheath subepider-mal cells were measured. NaCl...

Abstract Cystoseira mediterranea (Sauv.) extract was tested for its ability to restore barley ( Hordeum vulgare ) growth under salt stress (350 mM NaCl), shoot growth; membrane integrity; lipid peroxidation and hydrogen peroxide determination were performed. In normal conditions, the obtained data revealed of stimulate most parameters. However, it showed significant effect on parameters (plant ...

Hydrilla verticillata is an aquatic macrophyte recently found in the Upper Paraná River floodplain. This species has a high potential to reproduce and disperse to new sites, mainly through stem fragments. In this study, we evaluated the colonization (the ability of roots to develop), regeneration (the ability of lateral shoots to develop) and growth rates of this species using fragments of diff...

The effect of a metal mixture (Cu, Zn, Pb, and Ni) on Cd fractionation in sediment and its accumulation by the freshwater macrophyte Eriocaùlon septangulàre was examined in an in situ experiment in the littoral zone at the Experimental Lakes Area, northwestern Ontario, Canada. Fresh sediment was spiked with Cd alone and together with the metal mixture at three concentration levels. Macrophytes ...

Bulbs of tulip (Tulipa gesneriana L. `Gander'), in which the formation of ̄oral organs had been completed, were chilled at 28C for 3±30 weeks and then forced hydroponically at 208C under a 12 h photoperiod with the light at 100 mmol mÿ2 sÿ1. The fresh weight and the perianth length of the cut ̄ower highly correlated with the dry weights of shoots and ̄oral organs at anthesis, respectively. The d...

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...

in the recent years, increasing production of waste as a result of population growth, increased food consumption, industrial development and urbanization growth, is regarded as a serious challenge. vermicompost, as an end product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of vario...
