With the decrease in temperature, POD, SOD, and PPO activities overall showed an increasing trend.

In the other tested organs of “Ninghaibai”, the H 2 O 2 level presented an increasing trend under cold stress ( Figure 3D ).

These plants also showed a trend of higher leaf elongation and leaf biomass compared to plants growing in the absence of lucinid clams, but differences were deemed not significant by the statistical test ( Figure 2 ; Supplementary Figure S4 ; Supplementary Table S5 ).

Highly significant genotype and light quality effects and their interaction have been demonstrated on the architecture of rose.

Values of p < 0.05 and p < 0.01 were considered to be the significant differences and extremely significant differences, respectively.

In parallel, the flat-type group had an LN significantly higher than the non-flat-type cluster ( Figure 3E ); in fact, the highest LN values of the population were found for the unnamed accession ARD (12.0) and for the named landrace SPA9 (10.5), whereas the non-flat-type group showed a trend with a higher PI (range for the entire collection, 0.07–0.19) and FF (range for the entire collection, 28.78–89.42), especially for the MIN and FIA genotypes that resulted in those with significantly higher values for these traits in comparison with the other named varieties ( Figures 3F,G ).

The G × E interaction estimated by ANOVA was highly significant for all traits ( Table 1 ).

The significance level, α = 0.01, was used for the highly significant effect while α = 0.05 was used for the significant effect among genotypes.

Although we found no positive association of CHLM with other yield-related traits ( Supplementary Tables S2 − S5 ), we found a positive trend between CHLM and HTE2 ( Supplementary Table S5 ); thus, the presence of stay-green in these materials led to improved heat stress tolerance.

No significative difference was found for the other theses, although an increasing trend can be observed comparing T1 and T2 treatments with the control.

Five highly significant pathways, namely, “plant hormone signal transduction,” “phenylpropanoid biosynthesis,” “DNA replication,” “brassinosteroid biosynthesis,” and “cutin, suberin, and wax biosynthesis,” were co-accumulated by all three groups.

From 15 to 19 DAP, both lines showed a decreasing trend in pericarp thickness; however, M03 displayed a greater proportion of decline than M08 (28.8% in M03 vs. 13.32% in M08).

The interactive effect between irrigation levels and Zn and N rates was non-significant for leaf area duration and crop growth rate, while interaction between Zn and N levels in the case of leaf area index was significant at first sowing place, and interaction between irrigation levels and Zn application, while Zn and N application was highly significant at second sowing place.

The ratio of the number of identified foxtail and broomcorn millet seeds increased from 0.15 (Banpo Phase) and 0.31 (Miaodigou Phase) to 5.18 (Qijia Culture), indicating an increasing trend of foxtail millet cultivation importance in subsistence agriculture over time.

For those MET molecules that the high salt increases solubility, there may be significant enhancement in current production.

The phylogenetic analysis showed highly significant support (>98%) for the groups formed of samples from each genus and its correspondent reference sequences for the genus.

The enrichment of the flavonoid biosynthesis pathway and anthocyanin biosynthesis pathway was extremely significant, with the exception of the CK_vs_G3 group ( Figures 4A–D ).

The fact that the effect of inbred lines was found to be extremely significant on all the measurable parameters that were recorded in this study suggests that the exploited germplasm represents a rich source of genetic variation that can be employed for advanced breeding programs.

Under control conditions ( Figure 5A ), phenological traits including DT and DS showed highly significant positive correlation with each other (0.99 *** ), while both characters showed significant positive correlation with each of EL (0.51 ** , 0.46 ** ), SC (0.44 ** , 0.39 ** ), and EL (0.52 ** , 0.47 ** ), respectively.

The interactive effects of NaHS and Si showed a highly significant and positive correlation with PM H + -ATPase activity, photosynthetic pigments, essential minerals, RWC, proline content, and enzymatic antioxidant activities (catalase, peroxidase, ascorbate peroxidase, dehydroascorbate reductase, superoxide dismutase, and monodehydroascorbate reductase).

Salt issues affect about 20% of the total global land area and almost 40% of irrigated lands; this phenomenon shows an increasing trend, and 50% of total cultivated land worldwide is projected to be salinized by 2050 ( Urbanavičiūtė et al., 2021 ).

ABA production showed an increasing trend with increasing both salt and water stress levels.

In the first 3, 8, and 8 days, with the increase of salt stress, Salix linearistipularis , Salix matsudana and Salix gordejevii showed a trend of increasing first and then decreasing ( Figures 4A–C ).

In the first 3 days, the Na + /Ca 2+ of willow root leaves showed an increasing trend compared with CK, but the difference was not significant.

With the aggravation of salt stress and the prolongation of stress time, the Ca 2+ contents in the roots and leaves of the three species of willow showed a decreasing trend ( Figure 3 ).
