To identify the appropriate irrigation level for Pinus densiflora, a common reforestation species in Korea, we investigated their growth response characteristics according to different irrigation treatment levels for producing container seedlings with relatively high growth rate for higher survival rate when planted at the reforestation site. The container seedlings including control seedlings (no irrigation was applied) were grown in 104-cell trays were irrigated for 8 weeks from 15 weeks after seeding, at intervals of 1, 2, 3, 5, 7, 10, and 15 days. Analysis of the height growth, root collar diameter growth, and dry matter production of the container seedlings according to irrigation showed that the highest growth reaction was observed for the irrigation interval of 1 day. A shorter irrigation cycle resulted in better growth of the container seedlings, but overall, longer total root length were observed with an irriga- tion cycle of 3 days compared with cycles of 1 or 2 days. Quality index (QI) was the highest for the irrigation inter- val of 1 day, and tended to decrease with increase in the irrigation interval. Thus, it was determined that irrigation at intervals of 1-2 days was appropriate for growing Pinus densiflora container seedlings.

Abstract. To identify the appropriate irrigation level for Pinus densiflora, a common reforestation species in Korea,

we investigated their growth response characteristics according to different irrigation treatment levels for producing

container seedlings with relatively high growth rate for higher survival rate when planted at the reforestation site.

The container seedlings including control seedlings (no irrigation was applied) were grown in 104-cell trays were

irrigated for 8 weeks from 15 weeks after seeding, at intervals of 1, 2, 3, 5, 7, 10, and 15 days. Analysis of the height

growth, root collar diameter growth, and dry matter production of the container seedlings according to irrigation

showed that the highest growth reaction was observed for the irrigation interval of 1 day. A shorter irrigation cycle

resulted in better growth of the container seedlings, but overall, longer total root length were observed with an irriga-

tion cycle of 3 days compared with cycles of 1 or 2 days. Quality index (QI) was the highest for the irrigation inter-

val of 1 day, and tended to decrease with increase in the irrigation interval. Thus, it was determined that irrigation at

intervals of 1-2 days was appropriate for growing Pinus densiflora container seedlings.
