These beneficial effects were reduced following the SBW epidemic and dry conditions during the 1970s, resulting in a negative mean BAI long-term linear trend for spruce in mixed stands ( Figures 4 , 5B ) and in a positive trend for aspen in the same stands ( Figure 5H ), although aspen showed a growth decline after the mid-1980s ( Figure 4 ; Supplementary Figure 4 ).
Analysis of Sym10 sequences revealed only one valine-isoleucine polymorphism at #221 position, which was not specific for any pea allele, and valine-isoleucine substitution that was almost insignificant at both structural and chemical levels.
An increasing trend was observed for TSS content at all development stages, i.e., 4.97, 7.87, 9.77, and 10.67 at 10, 18, 26, and 34 DAP ( Figure 1C ), respectively, whereas watermelon flesh’s firmness was measured as 2.72, 2.05, 1.68, and 1.27 kg/cm 2 at 10, 18, 26, and 34 DAP ( Figure 1D ), which has an opposite trend compared with fruit weight and TSS. pH can reflect the change of watermelon acidity, high pH is consistent with low acidity. pH values were recorded as 4.95, 5.14, 5.33, and 5.66 at 10, 18, 26, and 34 DAP ( Figure 1E ), respectively, indicating a decrease in acidity during fruit development.
Nine classes were obtained through the analysis of all the DAMs, among which the content of candidate metabolites in classes 1 and 7 presented an increasing trend, with 49 and 52 DAMs, respectively, such as sucrose citrulline and histidine; in contrast, 65 candidate DAMs in class 4 showed a decreasing trend, similarly, in classes 5 and 6, the metabolites also showed a downward trend during the watermelon flesh development, and there were 30 and 38 candidate DAMs, such as naringenin chalcone, vanillin, salicylic acid, and adenosine ( Figure 2D and Supplementary Table 1 ).
As the experimental phase progressed, the nitrate contents of the stems and petioles showed an increasing trend in the N HHH treatment.
DPPH showed highly significant positive correlation with AHP, luteolin (LUT) ( r 2 = 0.88 * ), and FRAP ( r 2 = 0.64 ** ) indicating a strong association between phenolic compounds and antioxidant activity.
From these GWAS, we identified highly significant QTNs ( p -values below 10 −7 ) associated with seed weight obtained from optimal (9 QTNs) and heat stress (20 QTNs) growing conditions, as well as 2 QTNs potentially involved in plasticity ( Supplementary Figure 3 and Supplementary Table 5 ).
The predicted biomass showed a clear trend when plotted against days after the water stress treatment with the growth almost stationary in stressed plants and continuous in well-watered plants, which matched with general anticipation.
Compounds 3, 11, 20, and 31 exhibited an increasing trend after veraison in the berries from M1while those compounds did not show remarkable change in M2 ( Figure 6 ).
Both in terms of DFL and the CGDD requirements highly significant genotype × season (year) interaction was observed ( Supplementary Table 1 ).
As an overall trend in the variation of fitted-line slopes in relation to bioclimatic conditions was apparent, the relationship slope = f (aridity index, AI) was subsequently modeled by linear regression.
Interestingly, we identified a highly significant effect of breeding system, with a high proportion of selfing species associated with the presence of kin cooperation.
The quantitative differences between the two groups of data for comparison with P < 0.05 or <0.01) were shown to be statistically significant or extremely significant, respectively.
A clear trend toward more positive values of the X-variate 1 (component 1) due to the infestation of the plants was observed, i.e., from mel-cnt to mel+aph and from mel+endo to mel+endo+aph.
There is an overall trend of reduction in genetic diversity for most invasive plant species during introduction ( Dlugosch and Parker, 2008 ), although there have been rare cases of successful invaders that have shown higher levels of within population genetic diversity in the introduced range than in the native range ( Novak and Mack, 1993 ; Genton et al., 2005 ).
The response of SD, however, was generally nonsignificant to climatic factors except for PWQ and PDQ (marginally significant positive response; Table 2 ).
P < 0.05 was considered to be significant, and P < 0.01 was considered to be extremely significant.
The rapidly upregulated AtMnSOD showed a trend similar to that of AOX1A in response to MV stress ( Figure 7B , top), where AOX1A , a mitochondrial oxidative stress-responsive marker gene, was used as a reference.
azollae , FR led to barely significant accumulation of a PsbA transcript of low abundance (817 BM; 1.36 log2FC with 0.099 P adj; Supplementary Table 4 , N. azollae ).
PBZ inhibited KO, a cytochrome P450 monooxygenase class enzyme of the GA biosynthesis pathway (Tuna et al., 2008 ); thus, a highly significant decrease in the KO enzyme transcript level was seen in all cultivars on PBZ application.
Concerning the micronutrients ( Figures 3E–H ) and non-essential elements ( Figures 3I,J ), the P deprivation in the NS led to a decreasing trend in all the elements in the roots of cucumber plants, except for Mn, but caused an increase in the concentration of Fe, Mn, and Ba in the aboveground tissues.
Pretreatment with 6-BA for the two waxy corn inbred lines exposed to waterlogging stress conditions also resulted in an increasing trend in the activity of AsA-GSH cycle enzymes relative to that of non-sprayed plants.
We observed a decreasing trend in prediction accuracy over time, indicating that it is more difficult to predict AGB for latter DAPs compared to early DAPs.
There is no significant relationship between CV of yield and mean yield, but there is a highly significant relationship between CV of yield and maximum yield ( Figures 2C , D ).
Exogenous application of DE-GRSP, however, almost significantly decreased root total length, surface area, and volume compared to the control, with increasing DE-GRSP strength, except that there was no difference in root volume between 1⁄4 DE-GRSP and the control.
