Abstract Seasonally freeze-thaw ( FT ) processes affect soil salinisation in cold and arid regions. Therefore, understanding the mechanisms behind during winter spring is crucial for management strategies effectively alleviating this. This study aimed to explore characteristics their influences on water salt migrations clarify underlying mechanism of springtime western Songnen Plain, China. The spatiotemporal distributions salt, frozen depths temperatures were examined at 0–200 cm three...

MADS-box genes are classified into five categories: ABCDE, including SEP1 , SEP2 SEP3 SEP4 and other homologous genes, which play important roles in floral organ development. In this study, the cDNA sequence of HrSEP1 gene was cloned by RT-PCR confirmed that belongs to family. addition, subcellular localization experiments showed protein localized nucleus. We verified interaction with HrSOC1 HrSVP HrAP1 using yeast two-hybrid bimolecular fluorescence complementation assays. These jointly...

Abstract. Since the 1950s, heavy plowing of Mollisols, combined with a lack organic matter intake, has resulted in severe soil degradation northeast China. The use biochar combination fertilizer is sustainable method improving quality. In this paper, we conducted field experiments to explore response stability mechanism aggregate, dynamic properties carbon, and changes microbial community structure biochar. input levels were C1, C2, C3 (9.8, 19.6, 29.4 Mg C ha−1, respectively), while...

The incorporation of crop residues (e.g., maize straw) into the soil could promote or inhibit organic carbon (SOC) mineralization by affecting microbial activity, which is known as priming effect (PE), and a pivotal mechanism C cycle. However, community structure underlying PE remains elusive. Furthermore, effects on are poorly understood. Therefore, we conducted 120-day laboratory experiment using Mollisols China addition 13C-labeled stems (ST), leaves (LE), sheaths (SH) (1 %) to...

Many non-wood forest product (NWFP) plants are shade-obligate species, but current understanding about their foliar response to understory spectrum is quite scarce. To monitor light condition at large scale faces significant obstacles from heavy canopy shade and high cost of sensors arrangement. Therefore, we employed a novel methodology meter the relative ratio between plots under in open-air. In this study, number 34 natural Aralia elata populations were investigated for structure across...

Phragmites australis (common reed) distributed in brackish or saline wetlands, with significant ecological and economic values. Cultivating edible fungi is an exciting developing field reed utilization, proven to be a viable technology. However, it remains unclear how nutrient utilization efficiency differs between mushroom species. Globally, Pleurotus ostreatus the easily most bagged cultivated mushroom. Therefore, three species were used investigate of reed. A 2-year cultivation experiment...

Abstract The purpose of this study was to identify the fractal dimension and their relationships with alkalinity properties soils, evaluate potential as an indicator soil. Six soils increasing salinity (electrical conductivity 0.09, 0.18, 0.62, 0.78, 1.57 1.99 dS m −1 , respectively) were selected from western part Songnen Plain (China). Salt content, exchangeable sodium percentage, adsorption ratio other determined soil particle-size distribution (0–2000 μm) measured using a laser...

Managing carbon input from crop straw in cropland ecosystems could increase soil organic (SOC) sequestration to achieve C neutrality and mitigate climate change. The complexity of the chemical structures residue largely affects SOC sequestration. Fungi communities play an important role degradation residues. However, relationship between fungal community composition residues remains unclear requires further investigation. Therefore, a 120-day incubation experiment was conducted Mollisols...

Increasing cases of lake eutrophication globally have raised concerns among stakeholders, and particularly in China. Evaluating the causes waterways is essential for effective pollution prevention control. Xiao Xingkai Lake part connected to (Khanka) Lake, a boundary between China Russia. In this study, we investigated spatio-temporal variabilities water quality (i.e., dissolved oxygen (DO), total nitrogen (TN), phosphorus (TP), chemical demand (CODMn) ammonium-nitrogen (NH 4 + -N)) from...

Biochar and nitrogen fertilizers are known to increase soil carbon storage reduce loss as amendments, suggesting a promising strategy for highly effectively increasing productivity. However, few studies have explored the mechanisms of their effects on crop yield in terms active fraction enzyme activity, which ultimately limits potential application biochar combination with fertilizers. To evaluate effect fertilizer improvement black soils northeast China, field experiment was conducted...

Soil aggregate stability, as an important indicator of soil functions, may be affected by seasonal freezing and thawing (SFT) land use in high cold wet regions. Therefore, comprehensive understanding the effects SFT on stability orchards during winter spring is crucial to develop appropriate management strategies that can effectively alleviate degradation quality ensure sustainable development orchard ecosystems. To determine mechanism quality, water-stable aggregates were examined...

Heat-pulse technique (HPT) has shown promise for predicting soil water flux (Jw). This study evaluated the accuracy of HPT in Jw packed saturated columns quartz, sand, silt loam, and sandy clay loam. was predicted using maximum dimensionless temperature differences (MDTD), ratio downstream to upstream increases (Td/Tu), an improved Td/Tu method. Results indicated that predictions had a good linear relationship with measurements (R2 > 0.93). The underestimated varying degrees,...

The Hosta hybrid cultivar ‘So Sweet’, an important ornamental and widely used horticultural plant, is noted for its rich, fragrant white flowers. main aroma components of flowers are terpenoids, mainly monoterpenes. Until now, the terpene synthases responsible production in were not described. In this study, two synthase (TPS) genes (HsTPS1 HsTPS2) cloned characterized to further study their function. Furthermore, volatile terpenes ’So Sweet’ flower development stages from vitro enzyme tests...
