Woody and herbaceous plants are the main components of global terrestrial ecosystems, their growth, adaptation survival depend largely on metabolism shoots roots. Therefore, understanding size-scaling metabolic rates in woody plants, roots, is a fundamental issue ecology. However, few empirical studies have examined scaling exponents across wide range plant sizes. Using whole-plant chamber systems, we measured respiration entire root systems 96 species ( n = 1243) 33 463) from various...
Abstract As terrestrial plants are rooted in one place, their metabolism must be acclimatized to continuously changing environmental conditions. This process is influenced by different metabolic traits of plant organs during ontogeny. However, direct measurement organ‐specific rates particularly scarce, and little known about roles whole‐plant metabolism. In this study, we investigated size scaling respiration rate, fresh mass surface area leaves, stems roots 65 seedlings Fagus crenata Blume...
At a sedimentary site in an old mine site, Miscanthus sinensis formed patches, where Pinus densiflora seedlings could grow better compared with those outside the indicating that M . would improve P seedling establishment. The purpose of this study was to understand mechanisms by which facilitates survival considering soil properties, heavy metal tolerance, and root endophytes at site. is bare ground, contained high concentrations Fe, plants should be exposed Fe temperature stresses....
Aucuba japonica Thunb. is an evergreen understory shrub that grows naturally at a mine site. The soil contains high concentrations of heavy metals, and A . appears to maintain detoxification mechanisms against metals in the study site’s understory. This aimed investigate metal tolerance , considering possible roles arbuscular mycorrhizal root-endophytic fungi. We conducted fieldwork summer (canopy-foliation season) winter (canopy-defoliation measure leaves, branches, roots analyze...
Abstract Background and Aims To date, studies on terrestrial plant ecology evolution have focused primarily the trade-off patterns in allocation of metabolic production to roots shoots individual plants scaling whole-plant respiration. However, few empirical investigated root : shoot ratio by considering respiration at various sizes throughout ontogeny. Methods Here, using a chamber system, we measured rates, fresh mass surface area entire from 377 Fagus crenata individuals, germinating...
Mine drainage is a vital water problem in the mining industry worldwide because of heavy metal elements and low pH. Rhizofiltration using wetland plants an appropriate method to remove metals from via accumulation rhizosphere. Phragmites australis one candidate for this accumulation, forming iron plaque around roots. At study site, which was mill tailings pond Ningyo-toge uranium mine, P. has been naturally growing since 1998. The results showed that accumulated Fe, Mn, 238U nodal roots...
Chaetomium cupreum, a root endophyte in Miscanthus sinensis, enhances Al tolerance M. sinensis by changing aluminum (Al) localization and the production of siderophore, oosporein, which chelates for detoxification. Oosporein has various functions, including insecticidal activity, phytotoxicity, antifungal siderophore. In our study, we focused on detoxification effect oosporein as siderophore growth under exposure. addition, phytotoxicity to was confirmed compare with those Lactuca sativa...
For growing plants at mine sites, plant species that accumulate metals in tissues and are tolerant to high metal concentrations should be selected from the perspective of phytostabilization. However, eco-chemical or elemental information sites is limited. The purpose this study was identify can adapt natural growth via: (1) vegetation survey, (2) analysis soil plants, (3) detoxicant detection cells. Our survey indicated our site consistent with confirmed other previous reports. A. indica...
Six-year vegetation survey has been done at four sites of slope covering constructions in the former mine, considering effects environmental factors. Spraying green plants seeds spring enhanced establishment Artemisia indica var. maximowiczii from beginning, compared with Festuca rubra, which shows wintery grow pattern. On contrary, spraying before snowing F. would be tolerant winter time. Additionally, high soil volumetric water content influenced wet-tolerant native such as Typha...
Miscanthus sinensis Andersson naturally grows at mining sites and accumulates heavy metals, suggesting metal tolerance. This study aimed to elucidate the tolerance mechanisms of M. sinensis, which grew a mine site, considering root endophytes. Elemental analysis by inductively coupled plasma-optical emission spectroscopy showed that highly accumulated zinc lead in adventitious roots dead bark, exhibiting via these elemental removals bark. Phenolic high-performance liquid chromatography...
For revegetation of mine dumping sites, introduction tolerant plant species to tailings is needed. We compared initial shoot growth the plants grown in with that control Kanuma pumice evaluate tolerance among various species; one crop species, ine (Oryza sativa L. cv. Nipponbare); three yomogi (Artemisia princeps), medohagi (Lespedeza cuneate G. Don), and creeping red fescue (Festuca rubra L.); two native mizudokusa (Equisetum fluviatile L.) susuki (Miscanthus sinensis). The was...
