abstract：:Using intact leaves of Spinacia oleracea (L.), reversible temperature-induced changes in chlorophyll fluorescence emitted at room temperature and at 77K were studied. Interpretation of fluorescence at 77K was largely facilitated by developing a new method to minimize reabsorption artifacts (;diluted leaf-powder'). Lea...
