“…Soil substrate include Granular soil, general-purpose nutrient soil, grass charcoal soil and garden soil. P. massoniana fallen wood was collected from the West Campus of Guizhou University, and divided into different decay grades (Table 2 ) regarding the classification and determination criteria of forest coarse woody residue decay grades by previous studies 13 , 31 , 32 . The mosses were harvested from Guanshan Lake Park in Guiyang City, Guizhou Province.…”

“…Bryophytes had high water storage capacity 10 and nitrogen fixation capacity, which could promote the decomposition of fallen wood and increased the availability of soil nitrogen, and was conducive to the nutrient cycling and growth of forest. In recent years, a large number of studies had proved that bryophytes played an important role in forest regeneration and nutrient cycling 11 , 12 and grow better on fallen forest wood 13 , 14 . The degree of decaying wood affected the life shape and gametophyte growth of bryophytes 15 , 16 .…”

Soilless culture has been widely used in horticultural plant production, but little research has been done on bryophyte. In this study, we selected a cultivation substrate mixed and proportioned with garden soil, granular soil, grass charcoal soil, general-purpose nutrient soil, and decomposed grade II, III, and IV fallen wood of Pinus massoniana as the raw materials of soilless substrate to investigate its effects on the growth and physiology of Plagiomnium acutum. The results showed that the total porosity, water-holding porosity, and water-holding capacity of the mixed substrate containing fallen wood of P. massoniana were significantly higher than those of other cultivated substrates. The average cover of the P. acutum was significantly and positively correlated with the substrate’s total porosity and water-holding porosity. Chlorophyll content was highly significantly and positively correlated with the water holding capacity and total nitrogen content of the substrate. Among them, VIII decomposition grade Pinus massoniana fallen log:Vgrass charcoal soil = 1:1 (SW8) substrate had the highest overall evaluation index and the best overall growth condition of P. acutum. In summary, VIII decomposition grade Pinus massoniana fallen log:Vgrass charcoal soil = 1:1 (SW8) substrate can be the best substrate for cultivation of P. acutum. The addition of P. massoniana fallen wood to the soil substrate increased the total porosity, water-holding porosity, and water-holding capacity of the substrate, which was conducive to the growth of P. acutum and the increase of chlorophyll content.

“…The soil was subtropical yellow soil, and the vegetation was mainly coniferous forest with P. massoniana as the dominant species. Deadwood was classified into five decay classes (I, II, III, IV, and V) following the criteria of Yan et al (2005) and Liu et al (2020) (Table S1). For each DC, we collected four deadwood samples with similar site conditions and large reserves (20-40 cm diameter).…”

“…Deadwood undergoes different decomposition stages over time and under varying environmental conditions (Qi et al, 2023;Yuan et al, 2017), which can influence moss growth. For instance, Liu et al (2020) have found that the diversity of bryophytes on deadwood and the complexity of their spatial structure increase as the deadwood decays. Fukasawa et al (2015) have shown that the type of wood decay affects the gametophyte growth of bryophytes.…”

Plagiomnium acutum has a high value of landscape application and medicinal value, but there is a lack of related research on propagation and cultivation techniques. The deadwood substrate has rich nutrients and superior water retention properties, which will be conducive to promoting the growth of moss. Nevertheless, the underlying mechanisms by which deadwood influences moss growth are not yet fully unclear. In this study, we pulverized deadwood from five decay classes of Pinus massoniana into three distinct particle sizes. Through a pot experiment, we investigated the effects of decay class and physicochemical properties on the growth and physiology of Plagiomnium acutum, aiming to identify the most suitable growth substrate. The results indicated that both the decay class and particle diameter of deadwood significantly affect the substrate's physicochemical characteristics and the growth indexes of P. acutum, with the decay class exerting a more pronounced effect. The water‐holding porosity, water‐holding capacity, total nitrogen, total phosphorus, total potassium and lignin content of the substrate positively affected the growth of P. acutum, while the bulk density, void ratio, total carbon, carbon‐to‐nitrogen ratio, condensed tannin content and cellulose content had negative impacts. A comprehensive evaluation using a fuzzy membership function indicated that deadwood with higher decay classes (IV and V) was more conducive to the growth of P. acutum. Specifically, substrates from decay class IV with particle sizes of 10–20 mm provided the most favorable conditions for P. acutum and were recommended as the optimal cultivation substrate. The results of this study provide theoretical basis and technical support for the propagation and cultivation of P. acutum, and provide a foundation for further development of the industrial, pharmaceutical and environmental biotechnology potential of P. acutum.
