Significant ( p < 0.05) or highly significant ( p < 0.01) correlations were identified among the traits across the poplar germplasm population.
Excerpts
There were highly significant negative correlations ( p < 0.01, Figure 5 , Supplementary Table S2 ) between the quantum yield of regulated energy dissipation (NPQ) and leaf fresh weight (LFW), leaf dry weight (LDW), leaf area (LA), and leaf thickness (LT).
The cumulative evaporation at each stage shows a linear decreasing trend with increasing moisture content, reaching a highly significant level ( p < 0.01).
As shown in Table 1 , there were highly significant differences ( p < 0.01) in the polar axis length, equatorial axis length, P/E ratio, and the volume index of pollen among the 46 germplasm resources.
The brown module was highly significant and positively correlated with the highly resistant trait (R), with a correlation coefficient of 0.38 ( p < 0.01).
The analysis of variance revealed a highly significant impact of the aeration treatment on the soluble solid content, organic acid content, and sugar acid ratio of the tomatoes ( p < 0.01).
Correlation of Growth Indices of Oat (Avena sativa L.) Seedlings Under Different Stresses Under drought stress ( Figure 5 ), except for the significant correlation between the dry weight and root length, shoot length, and vigor index ( p ≤ 0.05), all other growth indices showed highly significant correlations ( p ≤ 0.01).
In all the extracts, highly significant ( p ≤ 0.01) total (0.9 < r < 1.0) and very strong positive (0.7 < r < 0.9) correlations, according to the Roemer-Orphal scale, were observed between AC values determined by ABTS, DPPH, and FRAP assays, as well as between TP and TNF values ( Figure 2 ).
Yield Components and Grain Yield In the 2019 and 2020 growing seasons, irrigation had significant effects on EC ( p < 0.01 in 2019, p < 0.05 in 2020) and had highly significant effects on GY ( p < 0.01) ( Table 4 ).
The different asterisks indicate significant differences at p < 0.05, extremely significant differences at p < 0.01, etc. 5.
There was a highly significant interaction between the slope aspect and position on NO 3 − -N, NH 4 + -N, and AP ( p < 0.01).
In Table 2 , the analysis of variance for grain yield and quality (protein content) revealed that the treatment, variety, and their interaction (treatment × variety) had a highly significant effect on the grain yield ( p ≤ 0.01).
Germination Test and Seedling Growth Test According to a comparative analysis of the physiological indices of ten seeds from the 24 maize hybrid seed lots of eight cultivars, the indices of three seed lots of the same cultivar all exhibited the same trend in change: 2023 seed lot > 2022 seed lot > 2021 seed lot; the differences in the vigour indices (such as the GI and VI) among the three seed lots of the same cultivar were significant ( p < 0.05) or extremely significant ( p < 0.01).
The Contents of C, N, and P in Different Ages of Stands in Soil Forest age significantly influences SOC, TN, and TP contents, with an observed trend of 25-year-old > 20-year-old > 12-year-old > 8-year-old stands ( p < 0.01, Figure 1 ).
Additionally, the analysis of variance results ( Table 1 ) showed that both the aeration ratio and nitrogen topdressing level exhibited highly significant ( p < 0.01) effects on tomato root vigor at the flowering stage and fruit expanding stage.
There were highly significant differences between the TT allele and the AA allele at p < 0.01 ( Figure 4 E).
Combined analysis of variance showed highly significant effects ( p < 0.01) of environments, genotypes, and the genotype by environment interaction (GEI).
The ANOVA revealed that the first main effect, i.e., the genotype effect, was highly significant ( p < 0.01) for all the agro-morphologies (60-day tillers, 90-day tillers, 120-day tillers, plant height, cane diameter, and cane yield) except germination and the number of millable canes, which were significant at p < 0.05.
Nonetheless, the GSH/GSSG ratio was positively impacted by the treatments containing extracts, with TS being moderately significant (** p < 0.01 vs. control group).
Effect of Mn Deficiency on Leaf Dry Weight and Leaf Phenotype In a two-way ANOVA ( Table 1 ), it was found that genotypes, MnSO 4 concentration, and genotypes × MnSO 4 concentration interactions had highly significant effects on shoot dry weight, root dry weight, and plant height of maize seedlings ( p < 0.01), except for the genotype × MnSO 4 concentration interaction, which had no significant effect on root dry weight ( p > 0.05).
Additionally, leaf pigments display highly significant positive correlations (0.847 < R < 0.958, p < 0.01).
Nitrogen fertilizer from the tasseling location to the grain filling stage had significant ( p < 0.05) and highly significant ( p < 0.01) effects on net photosynthetic rate, transpiration rate, and stomatal conductance, and the interaction between film mulching and nitrogen fertilizer had no significant impact ( p > 0.05) ( Table 3 ). 3.2.1.
The ANOVA showed that the types of stress, the variety, and their interaction had extremely significant effects on the total N content in the three wheat seedlings ( p < 0.01) ( Figure 2 ).
ANOVA revealed highly significant differences among treatments (F = 5.367, p = 0.014).
We observed highly significant differences ( p < 0.02) among sites only for other species cover on small islands (ranging from ca. 7.6% of Ibc to ca. 45.3% of Ids ).
