The adverse effects of salinity and PEG-induced water stress on growth of Matricaria chamomilla were assessed at the germination stage using osmotic solution of NaCl (0, -0.175, 0.358, -0.541, -0.716 MPa), and polyethylene glycol (PEG 6000) (0, -0.05, -0.1, -0.2, -0.3 MPa), respectively. Effect of NaCl salinity stress (0, 40, 80, 120 and 190 mM NaCl) at early growth stage of chamomile was also ...

Hyperosmotic stress caused by NaCl, LiCl, or sorbitol induces an immediate and short duration ( approximately 1 min) transient cytosolic Ca(2+) ([Ca(2+)](cyt)) increase (Ca(2+)-dependent aequorin luminescence) in Saccharomyces cerevisiae cells. The amplitude of the osmotically induced [Ca(2+)](cyt) transient was attenuated by the addition of chelating agents EGTA or BAPTA, cation channel pore b...

BACKGROUND Osmotic dehydration is a process of the partial removal of water which is based on immersion of material having cellular structure in a hypertonic solution. Osmotic dehydration is used as a pretreatment for the dehydration of foods before they are subjected to further processing such as freezing, freeze drying, vacuum drying. Management of spent syrup is one of the most important pro...

Ultrasound (US) is a promising technology, which can be used to improve the efficacy of processes in food technology and quality final product. US technique used, e.g., support mass heat transfer processes, such as osmotic dehydration, drying freezing, well extraction, crystallization, emulsification, filtration, etc. Osmotic dehydration (OD) well-known process applied processing; however, impr...

Expression of the alcohol dehydrogenase gene (ADH) of Arabidopsis is known to be induced by environmental stresses and regulated developmentally. We used a negative-selection approach to isolate mutants that were defective in regulating the expression of the ADH gene during seed germination; we then characterized three recessive mutants, aar1-1, aar1-2, and aar2-1, which belong to two complemen...

the aim of this study was to investigate the allelopathic effects of eucalyptus camaldulensis on germination and early seedling growth of festuca arundinacea under laboratory condition in order to determine the effect of pretreatments on decreasing the destructive effects of allelopathic compounds. the chemical stimulators used in this study included 3 levels of gibberellic acid, 3 levels of sa...
