Abstract
|
|
|
|
Various plastids in leaf and bracteal tissues of Cannabis sativa L. were examined by electron microscopy. Young chloroplasts without starch grain in mesophyll cells were ellipsoidal, and osmiophilic globules within them were common in stroma. During the plastid differentiation, the mature chloroplasts in mesophyll were changed in shape depending on the numbers and sizes of starch grain in stroma. Electron-dense granular substances were occurred along the outer membrane of chloroplasts in mesophyll. Typical plastids with reticulate body were present in the glandular trichomes. Electron-grey material appeared along the surface of a plastid. A light area in reticulate body is considered to represent junction point of thylakoids.
