Similarly, the response of total P showed an increasing trend and ranged from 171.90 to 465.34 mg kg −1 .

In contrast, in cultivar B a slightly significant (0.070) difference was found between the triploids, which decreased and the tetraploids, which increased compared to diploids ( Figure 1A ).

On the other hand, we recorded negative covariations between ITV and ST for CWM_LN and CWM_LN: LP under N and P addition, suggesting there were contrasting trends through ST and ITV, leading to weakening responses a decreasing trend of these leaf traits at the community level following nutrient addition ( Siefert and Ritchie, 2016 ).

tangutorum were fundamentally demonstrated as a possible response to the groundwater table, showing a highly significant positive correlation with the groundwater burial depth ( Dong et al., 2019 ).

It could be seen from Figure 6 that the droplet with a velocity of 2.212 m/s has the best spreading effect at each diameter with the interaction of droplet diameter and velocity, in which the spread area of droplets with three velocities at all three droplet diameters has a positive trend.

The correlation matrix indicated that the transcript levels of the genes, except CsaV3_6G046050 and CsaV3_5G032930, had a highly significant negative correlation with the relative growth rate in fruit length and had highly significant mutual positive correlations, suggesting that the asparagine synthetase gene, Cucumis sativus putative CCCH-type zinc finger protein CsSEF1, C. sativus BTB/POZ domain-containing protein At1g63850-like, CsaV3_3G000800, CsaV3_3G041280, and CsaV3_7G032930 are good markers of sugar starvation in cucumber fruit.

In our study, ZnO NPs application in 2019 did not show a significant trend in chalkiness.

In the 2020 trial, rice protein content showed a trend of increasing and then decreasing with increasing ZnO NPs application.

After 72 hours of low temperature treatment, the expression level of DnoNAC3 , DnoNAC7 , DnoNAC14 , DnoNAC62 , DnoNAC63 , DnoNAC65 , DnoNAC76 and DnoNAC78 genes showed a decreasing trend, and a total of 20 DnoNAC genes with DnoNAC5 , DnoNAC9 , DnoNAC10 , DnoNAC15 , DnoNAC19 , DnoNAC24 , DnoNAC28 , DnoNAC31 , DnoNAC37 , DnoNAC46 , DnoNAC53 , DnoNAC54 , DnoNAC55 , DnoNAC57 , DnoNAC58 , DnoNAC59 , DnoNAC68 , DnoNAC79 , DnoNAC84 and DnoNAC85 showed an increasing trend in expression, in which the expression of DnoNAC37 , DnoNAC57 and DnoNAC68 was significantly increased.

With the change of sub-regions R 1 to R 4 , the color feature values in channels B, G, L show an increasing trend at the same ripeness stage, and show a decreasing trend in channels a and S.

In GC-MS analysis, the differential metabolites mainly included organic oxygen compounds (5–23), organic acids and their derivatives (2–20), lipids and lipid-like molecules (8–10), organic heterocyclic compounds (2–7), phenylpropanoids and their derivatives (1–5), among others ( Figure 3 ), while the CK group combined with obstacle group analysis revealed that 19 metabolites were quantified ( Figure 2L ); 12 metabolites showed an increasing trend and 7 metabolites showed a decreasing trend (VIP>1, Table S3 ). 3.4 Metabolic pathways of differential abundant metabolites The above significantly altered metabolites are involved in several important metabolic pathways.

glomerata , dry matter yield, plant height, and coverage had highly significant positive correlations with each other, and highly significant negative correlations with dry/fresh ratio.

glomerata showed a trend of gradual increase with increasing fertilization gradient, except in 2019 and 2020; and peaked under the fertilization gradient of 40 t/hm 2 ( Figure 1 ).

sativa first presented an increasing trend, then decreased with increasing fertilization gradient, with a peak at 20–30 t/hm 2 fertilization gradient.

Overall, the soil moisture showed a trend of gradual increase with increasing soil depth, and the application of amendments resulted in significant increases in soil moisture content in the 0–40 cm and 40–100 cm soil layers.

Nevertheless, these markers showed a decreasing trend in response to PGPB and Se treatments in stressed plants, especially those PGPB-containing treatments (PGPB and PGPB+ Se).

Highly significant differences between environments, genotypes and GEI (Genotype x Environment Interaction) were detected by mixed ANOVAs for agro-morphological-quality traits.

Nevertheless, Si application did result in a significant trend of reversal of stress-induced changes in growth ( Figures 1 – 4 ) towards the control.

plurivora root infection, and the addition of Si) were shown to be nominally significant predictors of the total plant dry weight (DW; Table S1 ).

The combined effect of fire and N addition was marginally significant for fungus biodiversity, suggesting N addition for 1 year has limited capacity to mitigate the impact of fire.

Correlation analysis As shown in Figure 6 , the NAG (N accumulation amount in grain), NAL (N accumulation amount in leaf), NAP (N accumulation amount in plant), LAGR (leaf area growth rate), DMAR (dry matter accumulation rate), LIR (light interception rate of population), NS(number of population spikelets), FSE (fruiting spikelets per ear), GFRE (grain filling rate per ear), and Y (yield) were all significantly (p<0.05) positively correlated with each other, indicating that there were positive (significant or markedly significant) mutual promotion interactions among each factor.

In this study, SPA, SUA and SSA of the root zone at different growth periods showed a trend of decrease with the increase of soil depth.

With the increase of irrigation amount, SEC showed a decreasing trend, and the SEC of W3 level was 55.99% and 28.98% higher than that of W1 and W2, respectively.

Moreover, the other two flowering-related genes also showed a trend of up-regulation ( Figures 8D, E ).

However, given the falling trend for the cost of cultivation and a slight decrease in revenue, ( Figure 1H ) the profits reflect an increasing trend ( Figure 1I ).
