The vegetation cover showed a trend of degradation and then recovery, in which the percentage of high vegetation cover area decreased from 51.22% (1984–2000) to 28.33% (2001–2005), and then recovered to 55.69% (2006–2020).

Due to which, a decreasing trend in cultivable land and a rising world population raises a question of global food security.

With the increase in exogenous calcium content, the alleviation effect on the growth of Salix matsudana seedlings under salt stress showed an overall trend of increasing and then decreasing.

PlACLB2 was highly expressed in the red outer-petals that accumulated more acetyl-CoA and anthocyanin than the yellow inner-petals, and showed a positive trend with the spatial and temporal anthocyanin changes in P. lactiflora petals, and it was defined as a typical ACLB subunit with the nucleus and cytoplasm expressions.

There was a highly significant correlation between the expression levels of GPI ( DN21137_c0_g1 ), SUS ( DN7836_c0_g1 ), INV ( DN56_c0_g1 , DN1439_c0_g3 , DN534_c0_g1 , DN16555_c0_g3 , DN534_c0_g2 , and DN1915_c3_g2 ), HK ( DN26120_c0_g1 ), scrK ( DN7502_c0_g2 , DN7502_c0_g1 , and DN6713_c0_g1 ), MPI ( DN8158_c0_g1 ), GMPP ( DN3245_c1_g2 ), GMDS ( DN608_c0_g1 ), GALE ( DN159955_c0_g2 and DN11833_c0_g1 ), ERD ( DN8548_c0_g1 ), and sucrose content.

Compared with the control group, P < 0.05 is considered to be statistically significant and P < 0.01 extremely significant.

In terms of Cov within the canopy, the upper canopy coverage (Cov Upp ), middle canopy coverage (Cov Mid ), and lower canopy coverage (Cov Low ) all exhibited an increasing trend with an increase in the flight velocity, such that the Cov Mid at 1 m/s was 2.44%, and the Cov Mid at 3 m/s increased to 6.49%.

As the most significant part of the aboveground biomass (>99%), the arborous layer showed a decreasing trend in the aboveground biomass with the invasion progress.

However, the biomass of the shrub and herbaceous layers showed an increasing trend (shrub significant but herbaceous not), but they only occupied a small proportion (∼1%) of the total biomass.

When the original spectrum is transformed by the first derivative, the correlation with the chlorophyll content of jujube leaves is significantly enhanced in some wavelength bands, among which it reaches a very significant positive correlation at 660, 685, 735, and 754 nm, and at 550, 588, 633, and 702 nm highly significant negative correlation.

As shown in Figure 15 , a highly significant correlation ( R ≥ 0.77) was observed between qRT-PCR (log2 fold change) and RNA-seq (log2 fold change) data, thus verifying the authenticity of the identified core drought-resistant genes from XZSN in this study.

For all lines, TAG levels showed a decreasing trend over time and a corresponding increasing trend in FFAs ( Figure 2C ).

The long point type showed a decreasing trend with decreasing altitude.

This research focuses on the subtropical mountainous region with a monsoon climate of low latitudes in Southwest China to conduct phytolith morphology analysis of living plants and phytolith/pollen assemblages of topsoil to reveal the indicative significance of vegetation and climate.

ammodendron (34- and 46-year-old), and there was a decreasing trend with growth.

With decreasing GW levels, the soil water content showed a decreasing trend.

Notably, C i also showed a decreasing trend, suggesting that photosynthesis capacity might be limited by stomatal and non-stomatal factors ( Singh et al., 2013 ).

The differences in Cd concentration between different tissues under the same Cd treatment or in the same tissue under different treatments reached extremely significant levels.

pseudoacacia showed a decreasing trend in Rc.

variabilis , a higher percentage of consumption of stored nonstructural carbohydrates during drought events resulted in a positive trend in Rt-iWUEr (higher S Rt-iWUEr ), further limiting the ability of trees to recover following drought occurrences ( Galiano et al., 2012 ; Rosas et al., 2013 ).

variabilis showed an increasing trend in Rt, and R. pseudoacacia showed a decreasing trend in Rc.

Among them, manganese toxicity-induced root HD-ZIP I proteins (TDF #170-1 and 170-1k) showed a trend of up-regulation in both species ( Zhou et al., 2016 ).

With the time course of different treatments, the ratios of DEGs from DAS genes showed an increasing trend under dehydration and low temperature, ranging from 33% to 67% and from 35% to 61%, respectively, while it showed an opposite trend under NaCl treatment, with the ratio of 62% to 39% ( Supplementary Figure 5 ).

Starch content showed an increasing trend with snow removal years for specific performance.

Fv/Fm showed a trend where seedlings from the two species in the +4°C and +2°C environments had higher values than the seedlings in the control environment.
