Effects of Leaf Age and Exogenous Hormones on Callus Initiation, Rooting Formation, Bud Germination, and Plantlet Formation in Chinese Fir Leaf Cuttings
To guide the cultivation of superior Chinese fir plantlets, we designed an L16(4)4 orthogonal experiment to determine how leaf age and exogenous hormones influence key growth processes in leaf cuttings. -
Leaf resorption efficiency in relation to foliar and soil nutrient concentrations and stoichiometry of Cunninghamia lanceolata with stand development in southern China
Purpose The relationships among resorption, leaf nutrient status, and soil nutrient availability remain unresolved. Moreover, the dynamics of resorption in leaf and soil nutrients and stoichiometry during development of Chinese fir (Cunninghamia lanceolata) stands have rarely been studied. -
Litterfall production and nutrient return in different-aged Chinese fir (Cunninghamia lanceolata) plantations in South China
The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems. -
Biomass production, nutrient cycling and distribution in age-sequence Chinese fir (Cunninghamia lanceolate) plantations in subtropical China
Biomass production and nutrient (N, P, K, Ca and Mg) accumulation, distribution and cycling were quantified in young, mature and over-mature (10-, 22-, and 34-year old) Chinese fir [Cunninghamia lanceolate (Lamb.) Hook] plantations in southern China. -
Starch Hydrolysis Kinetics of Intermediate Wheatgrass (Thinopyrum intermedium) Flour and Its Effects on The Unit Chain Profile of Its Resistant Starch Fraction.
Background and objectives Intermediate wheatgrass (IWG) is an environmentally sustainable perennial crop with potential food applications. This study investigated the starch hydrolysis kinetics of IWG grown in Roseau (IWG-RS) and Rosemount (IWG-RM), Minnesota, USA and the molecular structure of their residual (resistant) starch after 2 hr hydrolysis. -
Enhanced electricity generation and organic matter degradation during three-chamber bioelectrochemically assisted anaerobic composting of dewatered sludge
Composting microbial fuel cells can generate electricity from recycled organic waste at accelerated degradation rates. However, the problem of high internal resistance (Rint), which results in low power density, is a technical obstacle related to this process, and the preferential conversion of the organic fraction by bioelectrogenesis remains unclear. -

Long-term straw retention drives carbon sequestration and crop productivity in dryland soils
Higher population densities in rural areas and climate change have necessitated technical change in crop production. Intensification without causing degradation is required to cope with changing population dynamics. -
