Excerpts

Although non-significant, we observed a decreasing trend in the 80, 60, and 40% fruit load treatments compared to the 100% fruit load treatment.

The results showed that the litter and root decomposition rate showed a trend of being first fast and then slow, and the decomposition rate of litter and root was greater than 50% after 300 days.

At 40 and 80 days after transplanting, the sugar beet taproot fresh weight showed a highly significant positive correlation with the ATP, EC, ATPase, and isocitrate dehydrogenase (IDH) data.

The results showed that the expression of the PfMYB44 gene showed a trend of first increasing and then decreasing under these treatments ( Figure 3 B,C).

Actual photochemical efficiency ( ΦPSII ), electron transport rate (ETR), and photochemical quenching ( qP ) indexes were significantly lower than that of the control under 10 °C, 0 °C, and −5 °C stress and showed a decreasing trend with decreasing temperature.

Compared to the control at 25 °C, the minimum fluorescence value ( Fo ) increased significantly under 0 °C and −5 °C stress, reaching a highly significant level at −5 °C.

Osmoregulatory Substances Proline content in stems and needles of the two families showed an increasing trend despite the temperature reduction, with the highest accumulation at 0 °C.

Biochar treatments were not consistent in their effects on rice leaf O 2 − content, which generally showed that rice leaf O 2 − content under B1, B2, and B3 treatments showed an increasing trend in both reproductive stages; the B2 treatment especially differed from the B0 treatment to a significant level in the heading stage ( Figure 3 B); however, the high-biochar treatment (B4) significantly decreased rice O 2 − content ( p < 0.05) under the N225 treatment at the heading stage and the N0 and N225 treatments at the filling stage, with O 2 − content under the treatments ( p < 0.05).

The positive correlations ( p < 0.01) between SuSase, AGPase, StSase, and SBE and the filling parameters were highly significant.

Specifically, there was an extremely significant correlation between the variation in DB content and the presence of DEMs 6-hydroxymelatonin, L-ornithine, Asp-Phe methyl ester, 4-hydroxy-3-methylbenzoic acid, β-cortolone, 3-methylcrotonylglycine, coenzyme Q2, 4-[2-(4-chlorophenyl) diaz-1-enyl]-2-methyl-6-(piperidinomethyl) phenol and D-threose, and significantly correlated with metabolites cytidine and 1-palmitoyl-Sn-glycero-3-phosphocholine, etc.

have a positive trend in response to low-temperature stress, and LcbHLH24 may act as a positive regulator because its typical ICE1 gene family structure [ 116 ].

gilva seedlings show a decreasing trend with the degree of drought stress.

gilva showed an overall trend of migrating toward higher latitudes and different periods under various climate scenarios, inconsistent with the results of this study [ 25 ].

During the 0–8 h of the PEG-6000 treatment, the change in the intercellular CO 2 (C i ) content showed a trend of first increasing and then decreasing in the hybrid and S. calendulacea , while it gradually increased in the leaves of S. trilobata ( Figure 5 H). 3.

For temperature, both the annual mean and the one from the warmest quarter, there is a clear trend of increasing values.

[ 37 ] revealed a highly significant correlation between total flavonoid and total phenol content in pear fruits and antioxidant capacity, with variations observed among different varieties.

For example, under Eth treatment from 0 to 48 h, when stable genes ( NCBP2 , CDC6 , UBQC and their combinations) were used as reference genes, the expression level of SsCS was the highest at 24 h and lowest at 12 h, with an overall trend of first decreasing then increasing.

SsHMGS , SsHMGR , SsFPS , SsMVD , SsEPH , SsCYP , SsSQS , and SsCS genes showed a decreasing trend in the High Tem treatment ( Figure 10 E), which suppressed the expression of these genes.

The correlation of the thermal-infrared indices constructed at different soil layers under soybean cultivation with SMC showed a trend of 0~20 cm > 20~40 cm > 40~60 cm. 3.4.

Analysis of forest and grassland coverage revealed that, under wet year scenarios, the vegetation coverage showed a significant trend of recovery, with an average recovery threshold of (75.4 ± 12.5)% and an average recovery potential of (8.5 ± 3.6)%.

Notably, however, ET in the southeastern plain region demonstrated a decreasing trend, which is strongly associated with human activities.

The findings reveal that ET exhibited an increasing trend in 84.17% of the Alxa Desert region, with a significant increase observed in 61.53% of the area, indicating positive outcomes from the implementation of the Three-North Shelterbelt Forest Program.

In 2022, the NH 4 + -N concentration showed an overall trend of C > CK, with the peak occurring 3 days after fertilization and reaching its lowest point at 7 days ( Figure 11 ab).

In 2022, the root-to-shoot ratio in the C pattern was consistently higher than that in the CK pattern, exhibiting an increasing trend from the tillering stage to the jointing–booting stage, followed by a declining trend in the remaining periods.

In 2023, the root-to-shoot ratio generally showed a decreasing trend, with higher values in CCD compared to CKCD, except during the jointing–booting stage where CKCD surpassed CCD.
