This study investigates the effect of Serendipita indica inoculation on growth, structural characteristics leaf epidermis, photosynthetic parameters, and antioxidant osmoregulation capacities Agrostis stolonifera L. under different drought stresses (normal moisture management: at 70–75% field capacity, low drought: 55–60% moderate 40–45% severe 25–30% capacity). The results showed that with S. significantly enhanced growth potential A. compared to uninoculated controls, then stress...

Background Drought stress is a major prevalent environmental factor impairing growth. Melatonin mitigates the impacts of drought on plants. However, melatonin’s role in Phoebe sheareri (Hemsl.) Gamble ( P. ) unknown. We aimed to reveal protective effects melatonin seedlings under conditions. Methods was sprayed or normal water The parameters, including growth, physiological factors, and phytohormones , were examined. Results Compared control group, inhibited growth significantly reduced...

Machilus microcarpa is a rare national tree species in China and possesses important ornamental ecological value. M. can be planted low-temperature areas, depending on whether its seedlings withstand the harm. To face this problem, annual of were subjected to five temperature treatments, eight physiological indicators measured. Furthermore, comparative transcriptome analysis was performed between leaves treated at 25°C -2.8°C. A total 9,385 differentially expressed genes (DEGs) involved...

Drought stress negatively impacts growth and physiological processes in plants. The foliar application of glycine betaine (GB) is an effective low-cost approach to improve the drought tolerance trees. This study examined effect exogenously applied GB on cell membrane permeability, osmotic adjustment, antioxidant enzyme activities Phoebe hunanensis Hand.-Mazz under stress. Two levels (0 800 mL) water irrigation were tested different concentrations (0, 50, 100, 200 mM). decreased relative...

Abstract MicroRNAs (miRNAs) have been shown to play key roles in the regulation of plant growth and development by modifying expression their target genes. However, influence miRNAs on root formation woody plants, such as Taxus chinensis , remains largely unknown. In current study, we explored phytohormone-response nutrition-response miRNA profiles during T. rooting quantitative real-time PCR (qPCR). We identified six miRNAs, namely, miR164a, miR165, miR167a, miR171b, miR319, miR391, eight...

The random amplified polymorphic DNA (RAPD) technique has been widely applied to identify different varieties of plants for molecular breeding. However, application RAPD markers parthenogenesis in not reported. In this investigation, we used pedigree and differentiate Taxus chinensis var. mairei cultivars that were associated with parthenogenesis. Among 180 eighty primers used, 108 generated bands from genomic T. (“Jingzhou” “Baokang”). Six hundred thirty-three loci...

Maintenance interval is one of the most important indexes in equipment maintenance strategy. In traditional planned strategy, often predicted by way statistical theory. This method lacks flexibility and can not adjust intervals according to actual situation maintenance. It will easily lead an under-maintenance or over-maintenance. order carry out individual maintenance, this paper, we use BP Neural Network predict dynamically intervals. At first, extract a lot models which exist historical...

In recent years, seeking solutions to urban waterlogging and water pollution has always been one of the topics concern. The problem accumulation occurs frequently in most areas China July August. contradiction between supply demand ecological is prominent. order solve caused by rainfall concentration, achieve overall goal building a water-saving green city, Shenzhen City should be built into sponge city. Under this background, physiological response different forages stress removal...

Experiments were conducted on 1-year Phoebe chekiangensis seedlings treated by different concentration (0, 300, 600, 900, 1200 mg/L) of Pb (NO3)2. Sixty days later, determination was implemented seedling growth, physiological and photosynthetic parameters. The results showed that the lower could promote growth seedlings. But with increase lead, P. height increment, ground diameter whole biomass, total root surface area, volume, length activity decreased, while root-shoot ratio present a...

The inverse scattering theory and algorithms developed within the distorted wave Born approximation (DWBA) in Devaney Dennison (2003 Inverse Problems 19 855–70) (2004 20 1307–24) are adapted to case of potentials that constrained be strictly real valued. In particular, it is shown constraint potential valued can cast into form additional data then incorporated directly DWBA reconstruction presented above two references. letter includes computer simulations illustrating improvement on quality...

Leaf nitrogen (N) status and stable isotope ratios of carbon (δ13C) (δ15N) were used to study environmental factors that control mountain individuals Picea neoveitchii trees, a coniferous species endemic endangered in China. From May September 2016, we carried out observations at four different altitude locations extending southeast Daba Mountain western Hubei Province. Needle-shaped leaf δ13C was positively correlated with needle N C content calculated from the area (Narea Carea content),...

A lobed leaf is a common trait in plants, but it very rare Lauraceae including species of Phoebe. In the study germplasm resources Phoebe neurantha, we found variant seedlings, and variation could be inherited stably. Studying mechanism P. neurantha var. lobophylla can offer insight into development woody plants. RNA-seq small analysis results showed that total 8091 differentially expressed genes (DEGs) 16 miRNAs were identified lobophylla. Considering previous research results, margin...
