To examine methods of overstory cutting in two-storied stands of sugi (Cryptomeria japonica) and hiba (Thujopsis dolabrata), clearcutting and thinning (45% cutting by basal area) of the overstory (50 ...
Discrimination of Sugi (Cryptomeria japonica D. Don) Plus-tree Clones Using SSR Marker Analysis
clone discrimination discrimination power SSR marker sugi plus tree
2009/8/28
Eight hundred and thirty-five sugi (Cryptomerica japonica D. Don) plus-tree clones from the Kanto Breeding Region were genotyped using three highly polymorphic SSR markers. With a mean observed hetero...
Mechanism of Female Sterility in Sugi (Cryptomeria japonica D. Don)
Cryptomeria female sterility male sterility megaspore mother cell
2009/8/28
Two C. japonica trees exhibiting male sterility were found in Niigata Prefecture, Japan. These trees exhibited not only male sterility but also female sterility, because their seeds did not germinate....
