Maternal control of seed size in plants.

abstract：:Examination of root tips from cucumber (Cucumis sativus L.) seedlings grown at 8 degrees C for varying periods ranging from 15 min to 96 h, showed marked changes in the ultrastructure of cortical cells within only 15 min of exposure. Greater parts of the cortex were affected with longer periods of exposure, but the se...
