Herbivory creates conflicts between a plant's need to allocate resources for growth and defense. It is not yet clear how plants rebalance resource utilization defense in response increasing grazing intensity. We measured characteristics of the primary secondary metabolism Leymus chinensis at five levels intensity (control, light, moderate, heavy extremely heavy). Furthermore, we evaluated hormone signaling by quantifying impact key hormones on plant Under light intensity, indole‐3‐acetic...
Abstract In temperate grassland ecosystems, grazing can affect plant growth by foraging, trampling, and excretion. The ability of dominant species to regrow after is critical, since it allows the regeneration photosynthetic tissues support growth. We conducted a field experiment evaluate effects different intensities (control, light, medium, heavy) on physiological biochemical responses Leymus chinensis carbon (C) sources utilized during regrowth. Light promoted regrowth photoassimilate...
Lalu wetland is the world’s largest plateau urban wetland. It was designated as a national-level nature reserve in China 2004 and often called “the lung of Lhasa”. serves vital recreational area for residents. Concerns have arisen about potential harm to human health due heavy metals (HMs) soil. This study assessed ecological risk HMs soil by using index geo-accumulation techniques. The findings showed that wetland’s overall level low risk. with Cd being primary pollutant. Through absolute...
Using Raman spectroscopy, energy‐dispersive X‐ray fluorescence and diffraction, the Pb–Sn–Sb triple oxide yellow lead–tin have been identified on two pieces of cloisonné enamel (Falangcai) porcelains. Lead–tin lead antimonate famille rose porcelains manufactured before after 1911, respectively. The replacement by that are discussed.
Abstract BACKGROUND Continuous cropping practices cause a severe decline in peanut yield. The aim of this study was to investigate the remediation effect Serratia marcescens on continuously cropped soil. A pot experiment conducted under natural conditions determine agronomic indices, soil microorganism characteristics, enzyme activities and antagonism ability typical pathogens at different growth stages. Four treatments were applied red as follows: an active fermentation liquor S. ( RZ ‐21),...
Abstract X‐irradiation at 77 K of a NaCl:Fe ++ crystal produces orthorhombic and axial Fe + ESR spectra comparable intensities. The corresponding (ortho) (tetra) centers are identified with, respectively, substitutional perturbed by nearest next cation vacancy. At 170 the vacancy jumps to neighbour position enhancing intensity. Above 215 moves away completely unperturbed (cubic) is formed. It concluded from this study that before either or vacancies occur in roughly amounts activation energy...
Atmospheric nitrogen deposition has increased in the last several decades due to anthropogenic activities and global changes.Increasing become an important factor regulating carbon cycle grassland ecosystems.Litter decomposition, a key process of nutrient cycling terrestrial ecosystems, is main source soil pool basis fertility maintenance.Elevated could affect litter decomposition by raising availability, increasing quantity quality inputs, altering microorganism conditions.Litter are...
A pot experiment was conducted to examine the effects of arbuscular mycorrhizal fungi, Glomus versiforme, G. mosseae, and intraradices on growth nutrition trifoliate orange (Poncirus trifoliata) seedlings under magnesium (Mg)-nontreated Mg-treated conditions. Whether treated with Mg or not, versiforme inoculation significantly enhanced concentrations Mg, phosphorus, calcium, potassium, zinc, copper in shoots roots, activities acid phosphatase, catalase, invertase, urease rhizosphere soils....
A 111>-oriented ${\mathrm{Tl}}_{2}^{+}$ center is produced above 220 K by x-ray irradiation of ${\mathrm{Tl}}^{+}$-doped KCl and RbCl. careful analysis the $X$-band electron-spin-resonance spectra establishes that two Tl nuclei are equivalent, which implies possesses inversion symmetry. The model proposed a on single cation site. Its production believed to involve trapping mobile anion vacancy between distant pair substitutional ${\mathrm{Tl}}^{+}$ impurities an electron in whatever...
摘要: 以超级稻中熟中粳徐稻3号为供试材料,研究麦茬田高、中、低3种地力水平下施氮肥(0、148.5、223.5、297.0、372.0、445.5 kg hm-2)对超级稻产量及其构成因素、氮素利用率、稻米品质的影响。结果表明:(1)徐稻3号的产量在不同施氮水平下均表现高地力>中地力>低地力的趋势;高、中、低地力上出现的最高产量对应的最适施氮量分别为260.8 hm-2、290.5 hm-2、345.5 hm-2。(2)氮肥表观利用率与施氮量之间存在显著或极显著的二次相关关系,高、中、低3种地力土壤条件下氮肥最高利用率对应的施氮量分别为268.6 hm-2、293.4 hm-2、335.2 hm-2。(3)培肥地力有利于稻米营养品质、加工品质、蒸煮食味品质的提高,不同地力土壤要施适量氮肥才可以改善稻米的外观品质,优化稻米的营养品质。综合以上超级稻高产、优质、高效的施氮范围,建议该区超级稻施氮范围为高地力田240.0~270.0 hm-2,中地力田285.0~315.0 hm-2,低地力田330.0~360.0 hm-2。
