Cellulose is the most abundant unique biopolymer in nature with widespread applications in bioenergy and high-value bioproducts. The large transmembrane-localized cellulose synthase (CESA) complexes (...
Water use efficiency (WUE) provides a direct measure of the inextricable link between plant carbon uptake and water loss, and it can be used to study how ecosystem function varies with climate. We ana...
2022年8月28日,南京农业大学耕作制度与农田生态课题组的最新研究成果“Temporal complementarity be tween roots and mycorrhizal fungi drives wheat nitrogen use efficiency”在New Phytologist上发表。该成果揭示了氮高效小麦品种在花前依赖根系吸收氮素而花后依赖丛枝菌根真菌(AMF)促进花前...

氮素是植物生长发育所需的大量元素之一,水稻是我国的主要粮食作物,水稻生产对氮的需求仅次于水,是构成水稻生长成本的主要部分。目前,水稻氮肥表观利用率只有39%,即施氮肥量的50%以上残留在环境中。因此,在保证产量不减的基础上如何提高氮肥的利用效率,减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。
Death Valley doesn't seem like the best place to ride out rising temperatures amid a changing climate. But for the desert plants that live there, it's home -- and they face the choice to adapt or die....
We explored the relationship between tree growth, water use, and related hydraulic traits in Populus deltoides Bartr. ex Marsh.and hybrid clones, to examine potential trade-offs between growth and wat...
The objective of this study was to calculate economic weights for ten current breeding objective traits and for four new traits characterising claw health and feed efficiency in Czech Holstein cattle ...
Wild capuchin monkeys readily learn skills from each other — but that social learning is driven home by the payoff of learning a useful new skill. It’s the first demonstration of “payoff bias” learnin...
Juniper forests grow in mountain areas and many difficulties are encountered in their sampling. Sector sampling as an unbiased and cost-effective method was tested for the sampling of a 12.5-ha junip...
This study aimed to investigate the effects of single or/and double strains of probiotic supplement on feed efficiency, growth performance, and microbial population in distal gastrointestinal tract (G...
The present study on German Shepherd bitches bred in the same environment of a private kennel and producing offspring for working purposes aimed to ascertain if any of the parameters: litter size, num...
The study compares the effects of: timer (‘Timer’) and soil moisture sensor-controlled irrigation on soilless lettuce; two volumetric water content (Θ) thresholds for irrigation (0.30 (‘Θ = 0.3’) and ...
The objectives of the trial were to investigate the effects of supplementing vitamin E (VE) on nutrient digestion, nitrogen (N) retention and plasma parameters of beef cattle in feedlot. Four growing ...
The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European tempe...
