Tree fern trunks facilitate seedling regeneration in a productive lowland temperate rain forest - Oecologia

Seedling regeneration on forest floors is often impaired by competition with established plants. In some lowland temperate rain forests, tree fern trunks provide safe sites on which tree species establish, and grow large enough to take root in the ground and persist. Here we explore the competitive and facilitative effects of two tree fern species, Cyathea smithii and Dicksonia squarrosa, on the epiphytic regeneration of tree species in nutrient-rich alluvial forests in New Zealand. The difficulties that seedlings have in establishing on vertical tree fern trunks were indicated by the following observations. First, seedling abundance was greatest on the oldest sections of tree fern trunks, near the base, suggesting that trunks gradually recruited more and more seedlings over time, but many sections of trunk were devoid of seedlings, indicating the difficulty of establishment on a vertical surface. Second, most seedlings were from small-seeded species, presumably because smaller seeds can easily lodge on tree fern trunks. Deer browsing damage was observed on 73% of epiphytic seedlings growing within 2 m of the ground, whereas few seedlings above that height were browsed. This suggests that tree ferns provide refugia from introduced deer, and may slow the decline in population size of deer-preferred species. We reasoned that tree ferns would compete with epiphytic seedlings for light, because below the tree fern canopy photosynthetically active radiation (PAR) was about 1% of above-canopy PAR. Frond removal almost tripled %PAR on the forest floor, leading to a significant increase in the height growth rate (HGR) of seedlings planted on the forest floor, but having no effects on the HGRs of epiphytic seedlings. Our study shows evidence of direct facilitative interactions by tree ferns during seedling establishment in plant communities associated with nutrient-rich soils.

식물 키울 때 자생지랑 양육 환경이랑 일치시킬 수록 좋다는거 누가 몰라?


누가 상토, 수태 구리데? 그냥 그게 좋으면 그거 써, 근데 본인 생각만 무조건 옳다, 내가 믿는것만이 진리야 이건 좀 위험하다.

"논문을 가지고 와라! 이건 뭔 개똥철학이냐?" -> ?


본인 소비 수준에 맞는거 쓰면 되는거지. 수입품에 비싸니까 그렇지


상식적으로 귀한 양치류 그대로 갈아다가 배합제로 만들었는데 정글 그대로 가지고 온게 구릴 수가 있겠니...

거기서 자생하는 식물이다보니 채집 쿼터까지 있음.


꼴랑 이게 뭐라고 바득바득 우기나 몰라,. 솔직히 너같은애들 한국에 워낙 많아서 놀랍지도 않아.

근데, 너같이 본인 말만 무조건 맞다고 이야기 하고, 남이 이야기 하면 까내리고 무시하는 사람은 좀 쪽팔림 좀 당해보면 좋겠다.


누가 무슨 말만 하면, 일단 부정부터 하고 봄


세계 최대 식물원이나 유명 가든에서도 트리펀 갈아서 쓰는데?

상토가 구려서 안쓰는게 아니라, 과습 통기 보비가 잘 잡히고 뿌리 발달이 다르니까 그렇지..


나도 수태나 상토도 쓴단다...
