Fig. 2From: Changes in the morphology and functions of vacuoles during the death of ray parenchyma cells in Cryptomeria japonicaLight micrographs of radial sections, stained with acetocarmine, showing nuclei in ray parenchyma cells a in the current year’s xylem, b in the middle part of the twelfth annual ring from the cambium and c in the inner part of the twelfth annual ring from the cambium. Higher-magnification images of d a fusiform nucleus, e an elliptical nucleus and f a condensed nucleus are also shown. d–f Higher-magnification images of a–c, respectively. Arrows indicate fusiform or elliptical nuclei. Arrowheads indicate condensed nuclei. Bars 20 μmBack to article page
