We investigated paternal contribution in artificial crossed-populations made by mixed pollen from plus tree clones of Cryptomeria japonica D. Don in Niigata Prefecture. Using six polymorphic microsate...
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...
We produced seeds of Cryptomeria japonica trees in a glasshouse miniature seed orchard to prevent pollen contamination. In the glasshouse, male flowers shed pollen from February 4 to March 27, 2002, w...
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....
An optimum allocation of selection weight on the traits that were related to carbon storage in the stem of sugi was investigated to establish criteria for choosing plus tree clones suitable for carbon...
Male sterile sugi (Cryptomeria japonica D. Don) trees, “Shindai 1,” “Shindai 5,” were found in Niigata Prefecture, Japan. There were no significant differences in the appearances of male flowers and n...
We have developed new type compost with waste sludge from a bean curd factory and applied it to the cutting bed of Cryptomeria japonica D. Don. The effects of the compost on the elongation of root and...
For a general assessment of the nitrogen status of sugi plantations in Japan, we measured nitrogen content in the needles of sugi (Cryptomeria japonica D. Don) trees growing at 531 sites across the co...
