Excerpts

Regarding summer precipitation, no significant trend was detected across China from 1957 to 2008, with a decreasing trend observed in the north and an increasing trend in the south.

This is consistent with the regression results, shown in Table 6 , where the second sampling season (Y2) reported highly significant lower outcomes.

However, the acteoside concentration in the immature leaves tended (Kruskal–Wallis H statistic p = 0.064) to show a positive trend with increasing light intensity, being 5.67 mg g −1 DM for L200, 10.0 mg g −1 DM for L300 and 12.8 for L400. 2.6.

Under stress conditions, gs at pod-filling showed a significant negative correlation with pod yield per plant in 2024, whereas in 2025, a negative trend was observed but the association was not statistically significant.

led to a dramatic and highly significant increase in 16S rRNA gene amplification specific to these bacterial strains ( Figure S2 ).

In both cultivars, the maximum stem number increased significantly with increasing density, whereas the productive stem percentage showed a decreasing trend.

In contrast, LS showed an increasing trend in WUE from D2 to D4 and then maintained a relatively high plateau at D4–D5, with only a slight and insignificant decrease (3.7–4.2%) at the highest density. 3.

Similarly, the BCF for lead showed a highly significant increase with both EDTA doses, rising from a baseline value of approximately 0.03 to 1.1.

In the ear-leaf Pearson correlation network, ZmSPL19 showed only a limited number of nominally significant correlations with known NUE genes, but these correlations suggested a weak bias toward positive association with assimilation-related genes and negative association with part of the uptake/transport module ( Figure 2 b).

In contrast, after 12 days of salt stress, TaRS15-3B overexpression lines exhibited a highly significant increase in POD activity and MDA content compared to a wild type [ 34 ].

When used, we obtained an R 2 = 0.533 (explaining 53.3% of total variance) and a highly significant p -value (≤0.001), indicating extreme differences both between and within the treatment groups ( Figure 15 B).

(3) Proline content Proline (Pro) content in alfalfa leaves showed an increasing trend with the progression of planting years and was significantly influenced by the type of water-retaining agent, the application rate, and their interaction ( p < 0.05, Figure 4 ).

The results showed that alfalfa plant height, stem diameter, leaf area, branch number, soluble sugar (SS), soluble protein (SP), and proline (Pro) all exhibited a decreasing trend with increasing cutting times.

Because highly significant differences were observed among plant species for all variables except relative consumption (RC), additional one-way ANOVAs were conducted for each species separately, with Si supplementation as the sole fixed factor.

In these overexpression lines, transcript accumulation of AmGGPPS1 was significantly downregulated, whereas AmGGPPS2 exhibited highly significant upregulation, with its expression level positively correlated with that of AmGPPS6 ( Figure 8 b).

As the depth of straw return increases, SM, SS, and DS type fulvic acid substances show an increasing trend, with the proportions of components in the three treatments being 34.8%, 51.1%, and 54.9%, respectively.

In the maize season, WSOC exhibited a highly significant positive correlation with SOC, as well as a significant positive correlation with FI, HIX, and component C1.

On the contrary, the proportion of tryptophan-like substances showed a decreasing trend, at 65.2%, 48.9%, and 45.1%, respectively.

OsAGO18 is assigned to the MEyellow module, which exhibits a highly significant positive correlation specifically with the “normal” developmental baseline and negative correlations with stress-induced states; Figure S2: Identification of transgenic plants.

The suitable habitat area of this forest exhibits a decreasing trend under different future climate scenarios when dispersal limitations are incorporated ( Figure 7 ).

wallichii forest to exhibit an overall trend of expansion and migration toward northwestern higher-latitude regions ( Table S1 , Figure 5 ).

Meanwhile, as the growth stage progressed, the stem breaking resistance of maize under all treatments exhibited a continuous decreasing trend, whereas rind puncture strength showed a trend of first increasing and then decreasing, reaching a peak at 15 days after the silking stage.

With increasing planting density, 100-kernel weight exhibited a decreasing trend.

Overall, correlations of varying strengths were detected among the measured traits, and most growth-related variables showed significant or highly significant positive correlations.

From P1 to P2 and from P2 to P3, the NDVI level of early-spring ephemeral plants showed a decreasing trend ( Figure 4 and Table 3 ).
