Method (Primary source): The numbers of refractile and non-refractile- plastids in the preparations were determined using a hemacytometer on a phase contrast microscope.
Comments "The value for mature wheat chloroplasts (310-320 genome copies/chloroplast, BNID 107107) compares with a figure for pea chloroplasts of 224±80 genome copies/plastid (primary source)...The published figures in primary source are too low by a factor of 16, as a result of an error in the use of the hemocytometer (J. Bennett, personal communication)."
