Excerpts

An analysis of the two-year averaged data revealed that maize yield and dry matter accumulation showed an increasing trend with elevated irrigation or nitrogen application rates under the same nitrogen or irrigation levels, respectively.

In contrast, the crude fat content exhibited an initial increase followed by a decreasing trend with rising nitrogen application.

When the irrigation amount was 100% ET 0 , as the nitrogen application rate increased, the number of effective pods per plant, the kernel weight per plant, the kernel number per plant, the 100-kernel weight, the yield, and the dry matter accumulation of soybeans all showed a trend of initially increasing and subsequently decreasing.

The results indicate that during salt stress, the light cyan module showed a highly significant positive correlation with E1, and the light yellow module exhibited a significant positive correlation with E1, with correlation coefficients of 0.93 and 0.54, respectively.

In contrast, the exponential trend for larger tree groups showed a negative trend, which may be attributed to the fact that the observation period was twice as short as that for individual trees.

Moreover, there is a clear trend of forest endangerment due to unfavourable climatic conditions—primarily drought— which compromise trees’ defence mechanisms against insect infestations, making them significantly more susceptible [ 67 ].

Notably, soil enzyme activities exerted a highly significant direct positive effect on Chinese cabbage growth (path coefficient 0.921).

Studies showed that plants exhibited an increasing trend in net growth rate and basal diameter under low Cd concentrations (≤10 mg·kg −1 ), whereas they exhibited a decreasing trend at high Cd levels (≥25 mg·kg −1 ) [ 38 ].

lobata , the SAP and SC/N increased with soil cover thickness, while the SNN showed a decreasing trend.

The Relationship Between Leaf Functional Traits of Vines and Its Relationship with Soil Factors In Figure 4 a, it could be observed that LNC showed a highly significant positive correlation with LN/P and SLA, while SLA had a highly significant negative correlation with LSW, LSD, and LDMC.

Analysis of variance revealed highly significant effects of environment, genotype, and genotype × environment interaction, demonstrating that protein content is influenced by both genetic and environmental factors ( Table 2 ).

On the other hand, water stress reduced seed viability in six out of the eight species, with four showing statistically significant differences and two exhibiting marginally significant differences.

However, both showed a decreasing trend in combined stress.

In this study, it was found that fertilization could promote the growth of Ochroma lagopus , and the height of trees in both upper and lower slope positions showed an increasing trend with the increase in fertilizer application, which is similar to the findings of Kulmann et al.

A similar pattern was observed regarding those relationships concerning supra-cellular anatomical parameters, since the correlation between f ias and T leaf was highly significant ( R = −0.68).

A clear trend was observed with higher frequencies and treatment times generally correlated with higher yields of both phenolic and flavonoid compounds.

Within the cellular component category, a notable number of DEGs were associated with cell wall-related structures, including “cell wall” (31 to 81 genes), “external encapsulating structure” (39 to 103 genes), and “apoplast” (8 to 25 genes), showing an increasing trend in DEG counts from G1 to G4.

Similarly, the grain number per panicle did not display an increasing trend with the increase in N fertilizer rate, and there were no significant differences in the grain number per panicle of N180, N225, and N300 ( Table 1 ).

This clustering was supported by the multiple comparisons test ( Table 5 ), where the ‘Soleta’ group was statistically different from ‘Belona’ (FDR = 0.045) and ‘Lauranne’ (FDR = 0.015) and showed a trend toward difference with ‘Guara’ (FDR = 0.065) and ‘Antoñeta’ (FDR = 0.079). ‘Soleta’ vs. ‘Makako’ was the only ‘Soleta’ comparison that did not reach any statistical significance (FDR = 0.135).

On the other hand, roots showed an increasing trend in total polyphenols when subjected to rising temperature or NPs treatment.

According to the different number of DEGs, the specific differentially expressed genes of ‘B1’ showed a decreasing trend with the extension of infection time, and ‘B1’ exhibited strong resistance to A. solani infection.

Meanwhile, D30 showed an increasing trend with the extension of infection time and exhibited no resistance to the infection of A. solani .

Although no significant differences were detected among the 0.5, 1.0, and 1.5 g·L −1 treatments, mean values showed an increasing trend.

The average PFPN increase rate of MNF showed an overall trend of first increasing and then decreasing with increasing nitrogen release period ( Figure 9 a).

The effect of MNF on PFPN showed a trend of first increasing and then decreasing with increasing elevation.
