Description

Cinnamomum camhora (L.) Sieb. is widely planted in many shrines and temples in Japan. To develop methods for genetic conservation of natural heritage trees and endemic evergreen broadleaved forests comprising this species, we tested the possibility of using plant cuttings for regeneration of old C. camphoratrees. The survival rate of cuttings taken from trees more than 100 years old was about 10%. The cuttings maintained some parent-tree traits, but early growth after establishment was greater than that of the seedlings. The leaves of cuttings showed higher photosynthetic rate earlier in the growing season than the seedlings and were more tolerant of water stress. These results suggested that if enough plants can be obtained, old C. camphoratrees can be regenerated from cuttings.
