Neck shrivel is a fruit disorder of european plum ( Prunus domestica L.). We investigate whether an asymmetrical distribution osmolytes might explain the observations turgid stylar end and flaccid stem end, in selection 17 cultivars sourced from two sites. The osmotic potential (Ψ Π ) juices expressed or samples decreased (became more negative) during development. cell turgor P slightly increas...

the aim of this study is to investigate drinking water contamination and to identify potential sources of contamination during the water production, delivery process and in water tanks in the kindergartens of gaza strip governorates. the samples were taken from water tanks in the kindergartens, water tankers and private desalination facilities in the gaza strip and analyzed for chemical and bio...

expansive soils are considered a worldwide problem as they cause extensive damage tocivil engineering structures. an important characteristic of expansive soils is theirsusceptibility to volume change due to the phenomenon of wetting and drying. this paperpresets the effect of pore water quality on the swelling and shrinkage behavior of anexpansive soil during wetting and drying cycles. thirty ...

germination is series of biochemical reactions that depends mainly on temperature and moisture. therefore, seed germination rate of lemon balm (mellissa officinalis l.) were evaluated in temperatures of 20, 23, 25,27, 30 and 32ºc and water potentials of 0, -0.2, -0.4, -0.6 and -0.8mpa. according to the results, germination temperature window was not very wide in a way that germination temperatu...

trees are an important source of wild germplasm for sustainable forestry. wild pear germplasm (pyrus boisseriana) was collected from a forest ecosystem and resistance potential to drought stress was surveyed in a greenhouse. in six-month seedlings, signs of leaf rolling appeared after 18 days without water (drought simulation). gas exchange parameters, such as net photosynthesis, stomatal condu...
