시비처리에 따른 후박나무의 생리 및 생장 반응

In the current study, four groups; control, 500, 1000, and 2000 ㎎/L, were treated to investigate the effects of physiological and growth characteristics on Machilus thunbergii under various fertilization levels. As a result of the physiological response to the fertilization treatment, the fertilized group demonstrated relatively higher levels of A, ITE, WUEi, Vcamx, PIabs, and SFIabs in comparison to the control. The best photosynthetic mechanism was most clearly seen at 1000 ㎎/L, which involved gas exchange through active stomatal opening and closing. For a productive photosynthetic mechanism. As seen in the growth response of M. thunbergii to fertilization treatment, the fertilized group has significantly higher height, DRC, leaf dry weight, stem dry weight, total dry weight, LWR, and SWR than the control group. A healthy seedling quality index was particularly evident at 1000 ㎎/L, and other growth indicators were also at a decent level. 500 ㎎ /L also demonstrated growth characteristics that were comparable to those at 1000 ㎎/L. As a result, M. thunbergii featured the best physiological and growth characteristics in response to the fertilization treatment at 1000 ㎎/L, and 500 ㎎/L also showed a similar trend, which is considered to be a good option from an economical perspective.
