Abstract

The effects of late weeding treatment on the growth of young hinoki (Chamaecyparis obtusa) during the sixth growing season after planting were examined. Furthermore, the contribution toward hinoki growth recovery of crown productivity (NAR) and biomass allocation to crown (CAR) were determined. In the late weeding plot, no decline in height growth was observed subsequent to weeding, and growth in diameter at breast height (DBH) and crown projection area (CPA) began to recover subsequent to weeding; however, DBH and CPA were reduced and experienced a 1- to 1.5-year growth delay compared to values associated with the weeding plot at the end of the second year subsequent to weeding. Relative growth rate (RGR) and NAR in the late weeding plot recovered and possessed similar values to those of the weeding plot in the second year subsequent to weeding. CAR values of the late weeding plot were similar to those of the weeding plot both before and after weeding. These results suggested that the recovery of NAR rather than that of CAR was primarily responsible for the recovery of RGR. The present study demonstrated that hinoki were able to quickly acclimate to an environment dramatically altered by late weeding and recover growth rate within a short period of time. The present study also showed that delays in crown expansion associated with late weeding may have impeded subsequent matter production. Therefore, it was concluded that late weeding treatments should be employed only when the associated delays in growth are taken into account.
