Drought is one of the most important environmental stresses that adversely affect plant growth and crop production will In order to study a factorial randomized complete block design with three replications in greenhouse Ardabil University mohaghegh was conducted in 2013. Treatments were water stress at three levels: 35%, 55% and 75% field capacity and seed inoculated with mycorrhiza growth pro...
ABSTRACT- Improper seed germination is a serious challenge for medicinal herbs under drought stress conditions in semi-arid and arid regions. A new group of plant growth regulators known as karrikins have been proved useful to improve seed germination in some plants. In this regard, the effects of karrikin on seed germination and vigor of three medicinals under drought stress were examined. See...
abstract: in this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. freeze drying is a separation process based on the sublimation phenomenon. this process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...
tomatoes (roma cultivar) picked up for the study were obtained from varaminelocal market. each tomato was divided into four portions. quarter portions of tomato were placed in osmotic solutions that were different in levels of sucrose and nacl (30 and 40% for sucrose, and 5, 10 and 15% for nacl). osmotic dehydration was carried out for varied time durations from 15 up to 240 min. temperature of...
Germination and seedling establishment are sensitive and important stages in the life cycle of plants that are affected by abiotic stresses, especially drought and salinity stresses. This study was conducted to investigate the effects of osmotic potential (due to sodium chloride and polyethylene glycol) on germination and biochemical indices of Salicornia sinus-persica Akhani spec. nov.Akhani s...
banana is one of the most important tropical fruit from commercial and industrial point of view. this fruit is an extremely perishable fruit which can not be preserved using freezing process. therefore, drying is the most promising method. conventional air drying is energy intensive and consequently expensive method. pre-treatments can be used to reduce the initial water content or to modify th...
