スギ及びアカマツの床替に於ける深植の影響について

(1) Some effects of deep-planting upon 1-0 Sugi (Cryptomeria japonica D. Don) and Akamatsu (Pinus densiflora Sieb. et Zucc.) seedlings in transplantation was examined.
(2) In general current height growth of seedlings of which the 1/2 or 1/3 of stem buried was larger than that of those correctly planted, although it was not statistically significant.
Namely, to say the least of it, deep-planting hadn't injurious influences upon the growth of seedlings in this case.
(3) Total nitrogen contents of leaves did not differ significantly between the degree of burying.
(4) Anatomic observations indicated that burying of stem promoted formation of periderm layers on Sugi, and chlorophyl in parenchyma of cortex disappeared on Sugi and Akamatsu.
