Abstract
In spinach (Spinacia oleracea) certain mitochondria of the sporogenic promeristem would appear to show lysosomal involvement. This occasional involvement occurs when the photoperiodic conditions do not favor flowering. The mitochondrial morphological changes indicate increase in the production of membrane. The acid phosphatase activity normally found in the neighbourhood of the dictyosomes is present.
