In contrast, the soil’s available potassium and available phosphorus of T1 and CK2 showed an increasing trend as the growth period advanced, which was significantly higher than CK1 in each period.

For osmotic stress, under low salt stress, the water potential of Brassica napus leaves decreased, and there was a decreasing trend in the soluble sugar content of most materials.

In this study, qP, Fv’/Fm’ and Φ PSII showed a decreasing trend ( Figure 2 A–C), indicating that HS restricted the photosynthetic electron transport of plants, resulting in the hindered synthesis of ATP and NADPH, and in a decrease in the assimilation of CO 2 in carbon reaction.

alopecuroides exhibited an increasing trend with higher irrigation levels ( Figure 1 C).

Although not clearly significant, the highest removals were observed in the Strelitzia reginae system (in both bed depths), achieving values of 79.4% and 86.3% for 60 cm and 40 cm depths, respectively.

In contrast, the southern part of Chamdo City in south-eastern Tibet and some areas adjacent to Shannan City and Nyingchi City are projected to show a decreasing trend in species richness ( Figure 1 ).

modelled the potential distribution of 151 plant species in the Hengduan Mountains, and the results showed an overall trend of species shifting to higher altitudes and latitudes, with plants in high-altitude regions expanding their range [ 7 ].

These regions show an increasing trend in wetland plant species richness and may provide many suitable habitats in the future ( Figure 4 ).

Oleanolic acid content in the transgenic hairy roots with overexpressed PgCYP716A264 , PgCYP716A391 , and PgCYP716A291 exhibited an increase, whereas that in the transgenic hairy roots with overexpressed PgCYP716BWv3 exhibited a decreasing trend ( Figure 8 E).

In addition, the expression of all genes showed a trend of green maturity higher than red maturity.

Among epiphytic fungi, Undefined Saprotroph was the functional gene with the highest relative abundance among all treatments, with a decreasing trend with increasing grazing intensity, with G0D being the highest and G5H the lowest.

As grazing intensity increased, species richness showed a trend of increasing and then decreasing, with G3 (21.14 ± 0.80) having the highest species richness and G0 (16.71 ± 0.80) the lowest, but there was no significant difference in species richness between G1, G3, and G5 ( p > 0.05).

Notably, a markedly significant upregulation of SpP5CS gene expression was observed specifically during soil drought conditions and upon subsequent rehydration treatment [ 37 ].

The average index of penetration ratio to root length of seedlings of both alder and maple species on skid trails showed an increasing trend with increasing age of the skid trails ( Figure 3 ).

The average main root-to-stem ratio index (MRL/SL) of alder seedlings on skid trails showed a decreasing trend with increasing age of the skid trail, while this ratio had a constant trend for maple seedlings ( Figure 2 ).

flexneri demonstrated a negative trend, with efficacy decreasing alongside the increase in concentration and the EO components presenting synergism with the bacterial strains, providing a strain-boosting effect.

PpNHX1 in “Explorer” and “Blue Best” showed an increasing trend, while PpSOS1 in both cultivars exhibited a declining trend after salt treatment ( Figure 7 B,C and Table S3 ).

The ethanol extracts exerted highly significant allelopathic inhibitory effects on all A. viridis growth parameters; the extracts using the water/ethanol ratios of 50:50 and 25:75 exerted intermediate inhibitory effects and the extracts using the water/ethanol ratios of 100:00 and 75:25 caused the least severe effects.

Similarly, [ 45 ] indicates an increasing trend in Ec level with phosphate application under different cropping system For organic carbon, all treatments significantly increased the percentage of this parameter in the soil.

What is more, the accumulated temperature throughout the whole winter wheat growth period ( Figure 4 b) in Henan Province ranges from 3145 °C to 3423 °C, exhibiting a clear trend of higher temperatures in the southern areas and lower temperatures in the north.

The B1 treatment was highly significant compared to the other single auxin treatments.

[ 53 ] found that, under the condition of moderate nitrogen content, the variation trend in water use efficiency was consistent with our results, while both nitrogen deficiency and nitrogen excess showed a decreasing trend with the increase in water stress.

At the same time, a highly significant positive correlation of the diameter of the rachis with the number of large vascular bundles, as well as with the area of large and small vascular bundles, was found.

Trp demonstrated highly significant negative correlations with four amino acids and a notably strong negative correlation with Met.

For example, in some studies on millet cultivation in certain regions, researchers have identified a series of millet varieties and observed an increasing trend in yield over time.
