Bamboo plants are an essential component of tropical ecosystems, yet their vulnerability to climate extremes, such as drought, is poorly understood due to limited knowledge of their hydraulic properties. , a commonly used tropical bamboo species, exhibited a substantially higher mortality rate than other co-occurring bamboos during a severe drought event in 2019, but the underlying mechanisms remain unclear. This study investigated the leaf and stem hydraulic traits related to drought responses, including leaf-stem embolism resistance (P; P) estimated using optical and X-ray microtomography methods, leaf pressure-volume and water-releasing curves.

We examined the effects of low temperature on egg hatching and killing rate of the 2nd instars of (J2) in the laboratory. We further evaluated the effects of two soil treatment methods on the survival rate of in northern China in a field experiment. The results of laboratory experiment showed that survival rate of J2 was 0 after being subjected to -7 ℃ for 24 hours, and that egg hatching was completely inhibited 24 hours after being subjected to -9 ℃.

Accurate prediction of photovoltaic (PV) output power is of great significance for reasonable scheduling and development management of power grids. In PV power generation prediction system, there are two problems: the uncertainty of PV power generation and the inexplicability of the prediction result. The belief rule base (BRB) is a rule-based modeling method and can deal with uncertain information.

We examined the barrier effects against and the potential to control the tomato yellow leaf curl virus (TYLCV) of different tomato-maize intercropping modes. Tomatoes (variety Jinshan 511) were planted at a fixed row distance either as a monoculture or together with maize (variety Xianyu 335) at the distances of 10, 20, and 30 cm. We investigated the viral index for TYLCV and the population density of .

Article Synopsis
  • Salvia miltiorrhiza, a traditional Chinese medicinal herb, was observed to be diseased in Luonan County, Shaanxi Province, showing stunted growth and wilting leaves, linked to root-knot nematode infection.
  • Researchers identified the root-knot nematode species by collecting juvenile and male nematodes from soil and females from affected roots, noting distinct morphological features for each.
  • Detailed measurements of the nematodes, including body size and structure, were taken, helping to characterize the pathogens causing the problems in the Salvia miltiorrhiza plants.

  • In Hainan province, Southern China, a tomato crop (cv. Jinsheng) faced yellowing leaves and root galls due to a nematode infestation identified as Meloidogyne graminicola in March 2021.
  • Morphological analysis of the nematodes revealed distinct characteristics of both female and juvenile stages, matching descriptions from the original scientific literature.
  • DNA extraction and species identification were successfully conducted using specific primers, confirming the presence of M. graminicola through amplification of a 369 bp DNA fragment.

Objective: This study aimed to develop an automatic classifier to distinguish different motor subtypes of Parkinson's disease (PD) based on multilevel indices of resting-state functional magnetic resonance imaging (rs-fMRI).

Methods: Ninety-six PD patients, which included thirty-nine postural instability and gait difficulty (PIGD) subtype and fifty-seven tremor-dominant (TD) subtype, were enrolled and allocated to training and validation datasets with a ratio of 7:3. A total of five types of index, consisting of mean regional homogeneity (mReHo), mean amplitude of low-frequency fluctuation (mALFF), degree of centrality (DC), voxel-mirrored homotopic connectivity (VMHC), and functional connectivity (FC), were extracted.

La(OH)-modified canna biochar (CBC-La) was prepared by a coprecipitation method (dipping method), and its phosphate adsorption characteristics were investigated. The results show that the pseudo-second-order kinetics and the Langmuir model can be used to describe the adsorption process with a high level of accuracy. Adsorption equilibrium could be reached at 8 h, at which point the maximum adsorption capacity was shown to be 37.
