Spatial analysis showed a clear trend of drought in the subtropical southwest, especially in the Sichuan Basin, which is consistent with previous research findings ( Li et al., 2012 ).

The results show that: 1) from 1952 to 2019, the interannual drought in subtropical China showed an increasing trend, with five extreme droughts recorded, of which 2011 was the most severe one; 2) the simulated average carbon storage of the EBF and ENF during 1985-2019 were 130.58 t·hm -2 and 78.49 t·hm -2 , respectively.

In contrast, the Zn release profiles of all treatments show a decreasing trend of Zn concentration after 48 h.

Overall, an increasing trend was observed in the MBC and MBN values at higher percentages of Zn amendment to the soil.

The difference in Nmin was clearly significant in the formulations with nano-Zn.

As the flowers gradually opening, the release of most volatile substances, including lipids, aldehydes, alcohols, ketones, and terpenes, showed a decreasing trend.

Additionally, from the perspective of the spatial pattern, the ES supply in the QTP showed a trend of gradual increase from northwest to southeast ( Figure 4 ).

Exogenous SPD influenced the photosynthetic physiological indicators in drought-stressed leaves The photosynthetic rate of leaves in the control treatment was maintained at approximately 12 μmol · m -2 -s -1 ( Figure 3A ) with an overall trend of decreasing photosynthetic rate as the degree and duration of drought stress increased.

Hence, a combined analysis of variance for agronomic traits of interest was carried out, and the results indicated that the location, genotype, and genotype × location effects range from not significant to highly significant and then to very highly significant for the entire agronomic traits observed in this study.

Specifically, when the spray pressure of hollow cone nozzle AA2-3W was 0.3Mpa, the spray coverage and droplet density show an increasing trend with the increase of wind speed, and when the spray pressure was bigger than 0.3Mpa, the spray droplet distribution increases first and then decrease with the increase of wind speed.

When the spray pressure reaches 0.7Mpa, the spray coverage increases with the increase of wind speed, but the droplet density showed a trend of increasing first and then decreasing.

Moreover, a mean value of pH of the wastewater has been observed within the safe limit except in a few sites following an increasing trend of TDS but within the safe limit.

The results showed that the correlation coefficient of W2SES and W4SES between the field and greenhouse reached 0.69 and 0.78, respectively, which was extremely significant.

In contrast, the temporal stability of SWC in deeper layers (200–400 cm) of 22-, 34- and 46-year-old stands showed a decreasing trend with depth.

The spatiotemporal behavior of SWC The SWC showed a trend of decreasing with increasing years of HA plantations, and the variation of SWC with plant years was greater in the deep layer than in the shallow layer.

In all association analyses, a highly significant locus on chromosome 10 was detected, which was tight chained with the known SCR resistance gene RPPC and RPPK .

As can be seen from the Figure 17 , with the increase of rotor speed, the average velocity of the wind field in the numerical simulation test shows an overall trend of increase, while the average velocity of droplets in the PIV test shows an overall trend of decrease, indicating that the wind field significantly reduces the average velocity of droplets.

Alleles of the high signal MTAs (locus IAAV3365, A/G alleles) had a highly significant effect on grain yield ( Figure 8A ).

At all three elevation sites, the threshold value of I when stemflow emerged showed a trend opposite to the acceleration of SF with I ( Figure 2 ).

The results showed that ( Figure 9B ), the genes of root development also showed a trend of overdominant expression.

TSS revealed a close to neutral correlation with most of the physiological, morphological and phenological traits except MAT (0.30) and SPAD2 (-0.31), where highly significant positive and negative associations, respectively, were observed ( Figure 1 ).

With the postponement of the water deficit stage, P n , G s , and T r showed an increasing trend, while C i showed a trend of decreasing at the beginning and then increasing later ( Figure 5D ), while LWUE showed a firmly decreasing trend ( Figure 5F ).

The accumulation of gibberellin 12 (GA 12), gibberellin 1 (GA 1), gibberellin 4 (GA 4), gibberellin 9 (GA 9), gibberellin 14 (GA 14), gibberellin 15 (GA 15), gibberellin 20 (GA 20), and gibberellin 53 (GA 53) showed a trend of first decreasing and then increasing during NaCl stress, with the highest levels reaching at 24 h ( Figure 5A ).

The total flavonoid content and the content of seven flavonoids in the leaves of Cymbopogon showed an increasing trend with increasing salt concentrations, and short-term salt stress also enhanced antioxidant enzyme activity in the leaves of Cymbopogon ( Lei et al., 2021 ).

After salt treatment, the levels of ABA, SA, and JA were significantly increased, the levels of GA were decreased, and IAA and tZ showed a trend of first increasing and then decreasing.
