Visualization of Freezing Damage
Freeze-cleaving can be used as a direct probe to examine the ultrastructural alterations of biological material due to freezing. We examined the thesis that at least two factors, which are oppositely dependent upon cooling velocity, determine the survival of cells subjected to freezing. According to this thesis, when cells are cooled at rates exceeding a critical velocity, a decrease in viabili...
متن کاملEvaluation of Freezing Damage in some Pistachio Seedling Rootstocks
A greenhouse experiment was conducted to evaluate the freezing damage in some pistachio rootstocks by ion leakage and pH changes of leaked solution. A factorial experiment was carried out in randomized block designs (RBD) with three factors: Temperature (A) including 4 ̊C, 0 ̊C, -2 ̊C, -4 ̊C, -6 ̊C, Time (B) including 3, 12, 24h , and Rootstock (C) including P. vera cv 'Badami Zarand' (V13) and 'Sar...
متن کاملEvaluation of freezing tolerance in olive cultivars by stomatal density and freezing stress
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
متن کاملEffect of antioxidant on sperm freezing
A major cause of male infertility, which includes 50 causes of infertility, is oxidative stress. The aerobic respiration in the sperm cell is associated with the production of reactive oxygen species (ROS). Some reactions such as sperm capacitation and acrosome reactions require moderate levels of ROS. However, when the amount of ROS production surpasses the natural antioxidant defense of the ...
متن کاملControlled-rate freezing of human ES cells.
A significant obstacle to using human embryonic stem cells (hESCs) arises from extremely poor survival associated with freezing, typically in the range of 1%. This report describes a slow controlled-rate freezing technique commonly used for mammalian embryo cryopreservation. Using a combination of surviving colony number and colony diameter; survival was determined relative to untreated hESCs. ...
