During the Heading Stage, most spectral vegetation indices selected under normal irrigation and drought conditions reached a highly significant level.

As shown in Figure 6 , the RGB channel intensities in the soybean strip image demonstrated an increasing trend from left to right (south to north), indicating a gradual rise in overall brightness.

In primed pepper leaves, amino acids (e.g., alanine, 4-hydroxy-proline, threonine), sugars (e.g., sucrose, fructose) and sugar alcohols (glycerol, myo-inositol) exhibited an increasing trend.

Notably, such a positive impact of the ANE extract on fruit Mg levels was recently reported in strawberries and raspberries as well ( Kazakov et al., 2024 ), pointing to a possible trend observable in multiple crop species.

Among the qualitative traits, a highly significant positive correlation was observed between panicle type and inflorescence density ( r = 0.50), while a highly significant negative correlation was observed between panicle type and branched spike length ( r = -0.24).

Introduction Maize is the second largest grain crop in China, with an overall trend of steady growth in acreage and production, and is widely used in food, feed, biodiesel and industry, which is of great significance to China’s production development.

IAA content showed a trend of decreasing, then increasing, and finally decreasing, reaching a low of 13.40 ng/g on the 10th day and peaking at 37.37 ng/g on day 20.

Statistical indicators confirm the model’s excellent fitting performance, as elaborated below: Statistical significance (p< 0.001):This indicates the overall regression relationship of the cubic polynomial is statistically highly significant.

Compared with the control treatment (0.0% H 2 O 2 ), the O 2 − and H 2 O 2 ( Figure 4 ; Appendix Table 2 ) contents in seeds treated with 0.1% and 0.2% H 2 O 2 showed an increasing trend and were significantly higher than those in the control group.

From SM to TC climates, both MAP and MAT showed a decreasing trend, and corresponding changes in soil nutrients indicated that the TC climate is under higher environmental stress.

Several sesquiterpenes, including δ-cadinene, β-selinene, valencene, longifolene, β-farnesene, humulene, α-farnesene, β-bisabolene, and (+)-α-Santalene, exhibited a clear trend of continuous accumulation during aging.

Festival showed the lowest increase in scavenging capacity (from 88.14% to 89.29%), yet still exhibited a positive trend. Second-year results were consistent, with elevated scavenging activity across all cultivars.

During salt-drought combined stress, when D1 was crossed with different salt concentrations compared to CK, plant height showed a decreasing trend with increasing soil salt concentration.

In contrast, the contents of soluble proteins, sugars, and proline showed an increasing trend.

Under the D2 treatment crossed with different salt concentrations, SOD, POD, and CAT activities showed a trend of initially increasing and then decreasing with increasing soil salt concentration compared to CK.

Conversely, the N∶P ratio showed an increasing trend, and the mean values were relatively high at low light intensities ( Figure 6F ). 3.3.

With increasing planting density, the concentrations of SOC, TN and NH 4 + in bulk soils exhibited a logarithmic increasing trend, while the NO 3 – concentration showed a decreasing trend across all functional groups, although these patterns were not all statistically significant ( Supplementary Figures S3A, C, I, K ).

Additionally, across all experimental treatments, LA, LAR, SLA, and LAI exhibited an increasing trend from seedling stage to fruiting stage of tomatoes, reaching the maximum values at fruiting stage, which was consistent with previous studies ( Chai et al., 2023 ; Wu et al., 2013 ; Zhang et al., 2022 ).

Generally, the decay rate of Pal ::GFP in aerosols showed a decreasing trend with rising temperature and falling RH ( Figure 3 ).

Throughout the entire tomato growing stages, both RBR and RSR under CF, BS75, FR+C, and BS100+C treatments showed a decreasing trend as plant growth stage progressed, whereas the other treatments followed a “decrease-increase” pattern.

Prediction accuracies displayed an increasing trend with an increase in the proportion of training set size and marker density in all three DH populations.

Similarly, the increase in stem length and leaf length were in an increasing trend in Experiment 2 ( Figures 4B , 5B ) where light intensities decreased over time.

Trends of NSC content under different nitrogen enrichment durations Nitrogen enrichment in woody plants generally showed a trend of initial promotion followed by suppression for NSC, soluble sugars, and starch contents in leaves, branches, and stems.

The spatial variation of the genomic diversity painted an increasing trend following the South-North ecological gradient, giving rise to four optimal genetic groups based on STRUCTURE analysis while the neighbour-joining analysis revealed three clusters.

In 2022, however, no significant differences in alpha diversity were observed among bog types, although wild bogs again showed a trend toward higher diversity.
