其他摘要:We compared the survival and growth between containerized (CT) and bare-root (BR) seedlings of Hinoki (Chamaecyparis obtusa) planted at different seasons (summer: August 2013, autumn: October 2013 and spring: May 2014) at Sanko national forest in Okayama Prefecture. Seedling survival rate was significantly higher in CT than BR and it was consistent with all three planting seasons. Survival rate for summer planted seedlings was much higher in CT than in BR (CT, 90%; BR, 57%). Growth rate in stem diameter showed no significant difference between two stock types for summer planted seedlings, whereas it was significantly lower in CT than BR for autumn and spring planted seedlings. Difference of height growth between the stock types was insignificant for seedlings planted in autumn and spring meanwhile CT showed significantly higher height growth than BR for summer planted seedlings. Planting period for Hinoki can be extended using CT including summer which was not suitable for planting in BR.
