Reversibility of chilling injury to corn seedlings.
Seedlings of corn (Zea mays) were tested for recovery from chilling injury incurred at 0.3 +/- 0.3 C. At 0.3 C visual leaf injury appeared in 36 hours, whereas stem and root injuries appeared later. Appearance of leaf injury was preceded by a rise in O(2) uptake and a lessened effect of 2,4-dinitrophenol on O(2) uptake by leaf segments and was accompanied by increased ion leakage from the leave...
متن کاملChilling injury is reduced in cucumber and rice seedlings and in tomato pericarp discs by heat-shocks applied after chilling
A number of abiotic shocks (e.g. heat-shock) applied before chilling have previously been shown to increase the chilling tolerance of cucumber and rice seedlings and of tomato fruit. The subsequent rate of radicle growth after chilling of these seedlings is a sensitive measure of chilling injury as is the subsequent increase in ion leakage from chilled discs of tomato pericarp fruit tissue. Dat...
متن کاملImbibitional Chilling Injury in Pollen
Chilling injury is sustained by dry pollen of Typha latifolia L. upon hydration in germination medium at 0°C. This injury is evidenced as poor germination, low vigor, and depressed respiration. Isolated mitochondria showed multiple sites of impaired electron transport. Besides losses of cytochrome (Cyt) c and NAD+, the activities of membrane-bound enzyme complexes such as Cyt oxidase, NADH-duro...
متن کاملChilling-Enhanced Photooxidation : The Peroxidative Destruction of Lipids during Chilling Injury to Photosynthesis and Ultrastructure.
Chilling-induced photooxidation was studied in detached leaves of chilling-sensitive (CS) cucumber (Cucumis sativus L.) and chilling resistant (CR) pea (Pisum sativum L.). The rates of photosynthesis and respiration, measured as O(2) exchange, were found to be comparable in the two species over a temperature range of 5 to 35 degrees C. Chilling at 5 degrees C for 12 hours in high light (1000 mi...
