In the downslope area with buttress roots, soil respiration generally exhibits a decreasing trend.

In the up-slope area with buttress roots, soil respiration showed an increasing trend followed by a decrease and then another increase, with peaks occurring around 11:00 and 17:00.

Compared with the current climate conditions, the future scenarios indicated a decreasing trend in suitable areas for K. evelyniana .

During the whole storage process, PPO activity showed a trend of increasing first and then decreasing.

The exo-β-1,4-glucanase content exhibited an upward trend ( Figure 8A ); in the R2 period, the exo-β-1,4-glucanase levels for the T1, T2, and T3 treatments increased by 10.00%, 20.00%, and 47.00%, respectively, compared to the CK (P<0.05), with T3 demonstrating a highly significant difference from the T1 and T2 treatments.

The present study found that the dynamics of straw decomposition and nutrient release also showed a trend from fast to slow under CK, T1, T2, and T3 treatments.

GWAS analysis of rose ornamental traits GWAS analysis of the association panel of 285 genotypes using the 68k WagRhSNP chip revealed several highly significant associations between SNP markers and eight of the nine phenotypic traits analyzed ( Figure 3 ).

The marker RhMCRND_201_1253 showed a trend towards lower values in allele dosage group 1; however, this group contained only five observations ( Figure 4C ).

The PCA results indicated that the first 20 principal components accounted for a substantial proportion of the genetic variance, exhibiting a decreasing trend, whereas the 10th and subsequent components explained less than 2% of the genetic variance ( Supplementary Figure S2 ).

A highly significant positive correlation was observed between LbWRKY97 and CAD6 . conversely, most relationships between AT1 , C4H2 and HHT1 genes and these LbWRKYs were negatively correlated.

Aboveground biomass and root biomass Both mowing treatments and sampling time had highly significant effects on the aboveground biomass of C. brevicuspis ( Table 1 ).

A clear trend emerges in RMSE values, where higher errors for SM reinforce its greater prediction variance, while lower values for SS confirm its consistency.

Findings from our meta-analysis indicate that since 2016, the use of drones in agricultural identification applications has shown an increasing trend, and its growth rate is also rising.

A clear trend of increasing seedling emergence rates was observed with longer priming durations, with the 24-hour soaking treatment showing the most significant improvement.

With the increase of irrigation and N rates, the cumulative N 2 O emissions showed an increasing trend.

In this study, we correlated light intensity, temperature and RH with single fruit weight, hardness, SSC, AC and flesh DMC, revealing a highly significant correlation between light intensity and the fruit quality attributes.

As shown in Figures 3b, c , from grades 0 to 4, the values of Gs and Tr showed a trend of first decreasing and then increasing, and the Gs and Tr of grade 2 were significantly lower than those of other disease grades ( p < 0.05).

At 1–3 days post-inoculation (dpi), the Ψ leaf of K326 did not change much, while that of Yunyan 87 showed an increasing trend from 1 to 2 dpi ( Figure 4a ).

From the perspective of OP&S, the BMF showed a trend of increasing with the increase of the open ratio.

From the perspective of UCI & K, FMF showed an increasing trend when the UCI of forest trees gradually increased.

The competition index, aside from its negative indirect effect through openness, had positive indirect effects through other indicators, leading to a highly significant positive correlation with FMF.

The openness ratios by age group were 0.916, 0.880, 0.804, 0.796, and 0.784, also showing a decreasing trend.

Functional involvement of the top highly significant genes GO analysis of top genes representing conserved up and down-regulation under stress conditions identified 47 and 3 significant GO terms ( p -value<0.001; FDR <0.05) for abiotic and biotic stress, respectively whereas 17 significant GO terms were identified for combined stress ( Supplementary Table 4 ).

4 Discussion 4.1 Characteristics of changes in vegetation phenology On the temporal scale, vegetation phenology in the middle and lower reaches of the Yangtze River exhibited a clear trend of advancement in the start of the growing season (SOS) and a delay in the end of the growing season (EOS), aligning with findings from previous studies ( Cui Hongjing, 2024 ; Han et al., 2024 ; Yang et al., 2022 , Yang et al., 2024 ; Zhu et al., 2024 ).

The annual average surface temperature is slightly higher than the annual average air temperature, ranging from 4.8°C to 29.27°C, and shows a decreasing trend with increasing latitude.
