Effects of Harvesting Intensity and Recovery Time on Understory Plant Diversity As shown in Table 3 , both harvesting intensity, recovery time, and their interaction had highly significant effects ( p < 0.01) on all four diversity indices: the Shannon–Wiener index, Simpson index, Pielou evenness index, and Margalef richness index.

Correlation Analysis of Soil Nutrients and Soil Enzymes From Pearson correlation analysis ( Figure 8 ), soil available P showed a highly significant positive correlation ( p < 0.01) with total p , with a correlation coefficient of 0.809; avail-able N showed a significant positive correlation ( p < 0.05) with organic matter and catalase, with correlation coefficients of 0.712 and 0.669, respectively; and organic matter showed a highly significant positive correlation ( p < 0.01) with catalase, with a correlation coefficient of 0.810.
The Correlations Among Biomass, Root Morphology and Architecture, and Non-Structural Carbohydrates Across both periods, the biomass of leaves, stems, and roots exhibited highly significant positive correlations ( p < 0.01) with both SS and ST ( Figure 6 ).
Sources of Variance for Yield Components and Grain Yield of Four Soybean Genotypes Across 13 Environments The combined analysis of variance across thirteen environments revealed highly significant effects ( p < 0.01) for environment (E), genotype (G), and genotype-by-environment interactions (G × E) for all measured traits ( Table 2 ).
TUE, TDW, IP, IPAR, and RUE of Different Ratoon Rice Varieties The treatment and variety, as well as their interactions, had an extremely significant effect on TDW in the ratoon season and the annual period ( Table 2 and Table 3 , p < 0.01).
Additionally, AP and SOM exhibited a highly significant positive correlation ( p < 0.01). 3.
Table 2 demonstrates that, with the exception of micro-topography exhibiting a significant correlation with SOM ( p < 0.05) and TP showing no significant interaction effect between micro-topography and vegetation type, all other soil nutrient factors exhibited highly significant correlations ( p < 0.01) with both vegetation type and micro-topography.
In addition, except for the early two years, a highly significant ( p < 0.01) correlation was also observed between the WC and wheat yield during 2018–2019, showing that a higher WC was consistent with a higher wheat yield ( Figure 5 ). 2.3.
Soil nutrients exhibited strong selective effects on growth parameters, and photosynthetic indicators and stomatal conductance showed consistent correlations with soil properties, demonstrating highly significant positive relationships ( p < 0.01).
In all graphs, *** indicated extremely significant differences ( p < 0.001), ** represented highly significant differences ( p < 0.01), and * displayed a significant difference ( p < 0.05). 5.
frutescens Leaves Highly significant differences in leaf yield and dry weight ratio were observed between the two types of P. frutescens with different leaf colors ( p < 0.01), with the L1 leaf color P. frutescens exhibiting a higher yield than L2.
The difference in phenotypic values reaches a highly significant level across all the environments ( p -value < 0.01).
The Simpson index, Pielou’s index, Shannon index, and Observed_species index between the SS treatment and PFA treatment were extremely significant ( p < 0.01), indicating that the addition of PFA and NACl could significantly change the diversity of fungal communities in the soil, and the application of PFA could significantly increase the diversity of fungi in the community. 2.5.
TR20 and HW both showed highly significant upward trends ( p < 0.01), with rates of increase at 0.02 days per year and 0.03 days per year, respectively.
MDA showed a highly significant negative correlation with SOD and CAT ( p < 0.01), a significant negative correlation with SS and NR ( p < 0.05), and a significant positive correlation with gallic acid ( p < 0.05).
The main effects of water supply (W) and genotype (G) on cane yield were highly significant ( p < 0.01).
Significant ( p < 0.05) or highly significant ( p < 0.01) correlations were identified among the traits across the poplar germplasm population.
The cumulative evaporation at each stage shows a linear decreasing trend with increasing moisture content, reaching a highly significant level ( p < 0.01).
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).
Both varieties exhibited a marked increase in lignin and pectin at higher temperature, with extremely significant differences ( p < 0.01).
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).
Extremely significant differences ( p < 0.01) were observed for the two index values tZR and ABA in the calyx abscission zones of both varieties from 21 April to 25 April, with the content in the calyx abscission zone of the YB variety significantly higher than that of the PT variety ( p < 0.01) ( Figure 2 A,B).
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.
