“…Emmenopterys henryi Oliv., a monotypic genus of Rubiaceae, is scarce and peculiar to China (Lu et al 2018), which is not only of value to the flora of China and the systematic evolution of Rubiaceae but also timber production, papermaking, and pharmacy (Lu et al 2018). Owing to damage of habitat, extensive deforestation and regeneration difficulty, E. henryi is endangered (Guo et al 2017). E. henryi is tall and deciduous tree with beautiful and fragrant flowers, which was described as one of the most strikingly beautiful trees in the Chinese forests by Ernest Wilson.…”

Influence of trehalose on photosynthesis in the rare and endangered Emmenopterys henryi Oliv. during heat stress and recovery process

et al. 2021

The effects of trehalose on photosynthesis of rare and endangered Emmenopterys henryi Oliv. in response to high temperature were investigated. Results showed that trehalose pretreatment not only alleviated heat-induced reductions of chlorophyll content, net photosynthetic rate (P N ), stomatal conductance (G s ), transpiration rate (T r ) and instantaneous carboxylation efficiency (ICE) but also advanced the recoveries of chlorophyll level, P N , water use efficiency (WUE), ICE, G s , and T r after removal of heat treatment. The decrease of the actual PSII efficiency (Ф PSII ), the maximal efficiency of PSII photochemistry (F v /F m ), photochemical quenching (q P ) and electron transport rate (rETR (II)) owing to high temperature were significantly mitigated under trehalose pretreatment. In addition, the recoveries of the initial fluorescence (F o ), F v /F m , Ф PSII , q P and rETR (II) were promoted by trehalose pretreatment after the cancellation of heat treatment. The results suggested that trehalose application relieved the damage of high temperature on photosynthesis in E. henryi and promoted its restoration, which might involve with mitigation of chlorophyll degradation, stomata regulation, improvement of ICE, renovation of PSII reaction center, allocation of more energy to photochemical reaction, and promotion of electron transport activity.

“…Huber's study also found that moss significantly inhibited the germination of grass seeds, with seed size directly proportional to the inhibition effect, but moss did not inhibit the growth of seedlings [103]. Guo's research showed that moss layers not only accumulate more Emmenopterys henryi seeds than bare layers but also reduce the germination rate of seeds [104]. In Jeschke's study, the physical barrier and shading effect of moss significantly inhibited seed germination and the seedling growth of four herbaceous plants [35].…”

The Role of Cryptogams in Soil Property Regulation and Vascular Plant Regeneration: A Review

Despite their small size, cryptogams (lichen, liverwort, and moss) are important for ecosystem stability. Due to their strong stress resistance, cryptogams often cover extreme environments uninhabitable for vascular plants, which has an important impact on the material cycle and energy flow of various terrestrial ecosystems. In this article, we review and discuss the effects of cryptogams on soil properties (moisture and fertility) and vascular plant regeneration over the past two decades. Cryptogams strongly affect soil water content by influencing precipitation infiltration, non-rainfall water input, soil evaporation, soil water holding capacity, and soil permeability, ultimately helping to reduce soil water content in areas with low annual precipitation (<500 mm). However, in areas with high annual precipitation (>600 mm) or where the soil has other water sources, the presence of cryptograms is conducive to soil water accumulation. Cryptogam plants can increase soil fertility and the availability of soil nutrients (TOC, TN, TP, TK, and micronutrients) in harsh environments, but their effects in mild environments have not been sufficiently investigated. Cryptogam plants exert complex effects on vascular plant regeneration in different environments. The primary influence pathways include the physical barrier of seed distribution, shading, allelopathy, competition, influences on ectomycorrhizal development and individual reproduction, and the regulation of soil water content, temperature, and nutrients.

“…Wood and wood-based composites have unique properties and are considered suitable materials for many applications, but in some cases property issues, such as water absorption and susceptibility to deteriorating fungi, could obstruct service (Tajvidi et al 2016;Soykeabkaew et al 2017). Many studies have therefore been focused not only on cultivation and regeneration of trees and wood (Daly-Hassen et al 2014;Arce and Moya 2015;Fernandes et al 2017;Guo et al 2017), but also on the inherent characteristics of wood and composites in order to find ways to eliminate their drawbacks (Candan and Akbulut 2014;De Almeida Andrade et al 2016;De Medeiros et al 2016;Bastani et al 2016a;Altuntas et al 2017;Poletto 2017;Sandberg et al 2017).…”

Fibre direction cylindrical specimens from the sapwood and heartwood areas of Paulownia wood were heat treated at 180, 190, and 200°C split in eight groups of ten specimens each. Air and water permeability were measured, thereafter. Results demonstrated that heat treatment had a positive effect on air permeability both in sapwood and heartwood specimens. That increase might be attributed to the development of cell wall micro-checks caused by thermal degradation and fracture of the vessel tyloses. Liquid permeability was significantly decreased as a result of heat treatment.
