As with NR, GS activity also showed an increasing trend in leaf and root tissues though the N-induced enzyme induction was not as pronounced as in NR, except for the G3 leaf tissue ( Figure 6B ). 3.4 Nitrogen supply increased auxin, gibberellin and cytokinin content and nitrate reductase activity remarkably, but not so for abscisic acid and glutamine synthetase Inorganic N application had a remarkable effect on endogenous hormones in both G152 and G3 accessions ( Table 2 ).

According to the spatial variation trends in drought ( Figure 3B ), SPEI 12 showed a decreasing trend in 62.13% of the region, with an overall decrease of 0.036(10 a) -1 .

Spatial analysis showed a clear trend of drought in the subtropical southwest, especially in the Sichuan Basin, which is consistent with previous research findings ( Li et al., 2012 ).

The results show that: 1) from 1952 to 2019, the interannual drought in subtropical China showed an increasing trend, with five extreme droughts recorded, of which 2011 was the most severe one; 2) the simulated average carbon storage of the EBF and ENF during 1985-2019 were 130.58 t·hm -2 and 78.49 t·hm -2 , respectively.

In contrast, the Zn release profiles of all treatments show a decreasing trend of Zn concentration after 48 h.

Overall, an increasing trend was observed in the MBC and MBN values at higher percentages of Zn amendment to the soil.

The difference in Nmin was clearly significant in the formulations with nano-Zn.

The p < 0.05 and p < 0.01 were considered as significant and highly significant change with respect to control. 2.4.

Overall, on the QTP, the BBB size followed a rainfall gradient with a decreasing trend toward drier and warmer areas.

Moreover, a mean value of pH of the wastewater has been observed within the safe limit except in a few sites following an increasing trend of TDS but within the safe limit.

The results showed that the correlation coefficient of W2SES and W4SES between the field and greenhouse reached 0.69 and 0.78, respectively, which was extremely significant.

In contrast, the temporal stability of SWC in deeper layers (200–400 cm) of 22-, 34- and 46-year-old stands showed a decreasing trend with depth.

The spatiotemporal behavior of SWC The SWC showed a trend of decreasing with increasing years of HA plantations, and the variation of SWC with plant years was greater in the deep layer than in the shallow layer.

In all association analyses, a highly significant locus on chromosome 10 was detected, which was tight chained with the known SCR resistance gene RPPC and RPPK .

If β > 0, NPP showed an increasing trend; if β< 0, NPP showed a downward trend.

The average NPP of different land use types changed at different rates and showed a trend of fluctuating growth.

(2021) observed a decreasing trend in GPC over the last 85 years using a DW collection including accessions representative of the Argentina, Italy, Chile, France, CIMMYT and other countries breeding programs.

The genetic correlations among traits were calculated ( Figure 2 ), showing highly significant coefficients between grain and flour protein (1.00).

The results showed that: 1) with increased grazing intensity and enhanced human activities from 1990 to 2015, the grasslands of the northern Tibetan Plateau were greatly degraded, most of which was converted into the barren land, and the conversion proportion was as high as 90.84%, which lead to a decreasing trend of the current density of ecological network in most counties and deterioration of ecological connectivity; 2) fencing construction has reduced regional current density, while fencing intensity is positively correlated with current density loss at county scale.

With the postponement of the water deficit stage, P n , G s , and T r showed an increasing trend, while C i showed a trend of decreasing at the beginning and then increasing later ( Figure 5D ), while LWUE showed a firmly decreasing trend ( Figure 5F ).

The accumulation of gibberellin 12 (GA 12), gibberellin 1 (GA 1), gibberellin 4 (GA 4), gibberellin 9 (GA 9), gibberellin 14 (GA 14), gibberellin 15 (GA 15), gibberellin 20 (GA 20), and gibberellin 53 (GA 53) showed a trend of first decreasing and then increasing during NaCl stress, with the highest levels reaching at 24 h ( Figure 5A ).

The total flavonoid content and the content of seven flavonoids in the leaves of Cymbopogon showed an increasing trend with increasing salt concentrations, and short-term salt stress also enhanced antioxidant enzyme activity in the leaves of Cymbopogon ( Lei et al., 2021 ).

After salt treatment, the levels of ABA, SA, and JA were significantly increased, the levels of GA were decreased, and IAA and tZ showed a trend of first increasing and then decreasing.

Five SA signal transduction related genes ( Solyc02g069310 , Solyc04g040220 , Solyc10g079460 , Solyc10g079750 and NPR1 ) were upregulated, while TGA transcription factors were generally showed a decreasing trend ( Figure 3E ).

Genetic components of plant development in the group of 188 winter wheat cultivars Two-way ANOVAs were carried out on the various phenotypic traits, and both main factors—genotype and year—were highly significant components of trait variances ( Supplementary Table 1 ).
