In contrast to the increasing trend, the tree radial growth rates at the high altitude showed a decreasing trend across years.

2.5 Multispectral image features extraction 2.5.1 Selection of vegetation index By combining different bands linearly or nonlinearly, the vegetation indices constructed has certain indicative significance for the dynamic changes of vegetation canopy information, which not only reduces the influence of atmospheric and soil environmental factors but also enhances the sensitivity of LAI to canopy reflectivity.

Statistical significance was declared at p ≤ 0.05 and a statistical trend was declared at 0.05 < p ≤ 0.10. 3.

Heritability estimates did not necessarily increase with the increase in stress; a few traits indicated an increasing trend, while others showed a declining trend.

Highly significant mean squares due to the genotypes and their partitions, parents, crosses, and parent versus crosses were detected for all the studied traits except for total chlorophyll content under normal irrigation conditions.

The relative content of trehalose and sucrose produced by the sugar metabolism process was higher under the SN treatment than under the DN treatment and showed a trend of decreasing and then increasing under both treatments as the plants grew and developed, while the pyruvate produced by the glycolytic process produced lactate under the action of lactate dehydrogenase, and the change in its relative content was consistent with the trend of trehalose content.

With the growth process (the increase of stress time), the relative content of N, N-dimethylarginine showed an increasing trend under both conditions, while the relative content of L-malic acid showed a decreasing trend and the relative content of succinic acid showed a decreasing trend followed by an increasing trend.

Results We found that GZnC of the wheat accessions showed an increasing trend with their released years, indicating that the dominant allele of GZnC was not lost during the breeding process.

The results of qRT-PCR showed that the expression profiles of ChDof1 , ChDof3 , ChDof7 , ChDof9 , ChDof11 , ChDof12 , and ChDof17 were similar and tended to increase with storage time; the expression of ChDof2 , ChDof6 , ChDof10 , and ChDof25 first increased and then decreased; the expression of ChDof4 , ChDof8 , ChDof19 , ChDof22 , and ChDof24 first decreased and then recovered; the expression profiles of ChDof5 and ChDof25 showed a decreasing trend; and the expression of ChDof15 , ChDof18 , ChDof20 , ChDof21 , and ChDof23 showed little change.

Citric acid content showed a trend of decreasing first and then increasing from white to initial red stage, and decling-rising- decling from initial red to dark red stage ( Figure 1C ).

hortensis , violaxanthin showed a decreasing trend with increasing salinity in both light regimes.

Nitrogen use efficiency indices are influenced by changes in nitrogen scheduling Partial factor productivity of nitrogen (PFP N ) and agronomic NUE showed a decreasing trend as the rate of N application increased.

The QTL analysis identified 12 and 8 major effect QTLs but in case of GWAS analysis was identified 19 and 28 highly significant SNP trait associations (STAs) in NAM_Tifrunner.

Additionally, it was decreased by 19% at 72 h, which was extremely significant.

Across the whole transects, leaf C, N, and P stoichiometry showed no obvious trend, but soil C and N concentrations showed an increasing trend, and soil P concentrations showed a decreasing trend with the increasing longitude.

During the early stage of Mn stress (12 h–30 days), MDA content showed a trend of rising first and then decreasing.

Results Phytoremedial potential parameters such as the bioconcentration factor (BCF) and translocation factor (TF) displayed an increasing trend with the increase of Mn concentration.

Results Effect of different altitude on starch composition of potato As shown in the data in Table 2 , the content (%) of amylose and amylopectin and the ratio of amylose/amylopectin in potato tubers reached extremely significant levels among different varieties, different altitudes and the interaction between varieties and altitudes.

Among the physiological traits, chlorophyll content demonstrated a highly significant positive paired association with CMS, PH, SL, ψ w , and TGW under the combined application of drought and heat stress compared with the individual stress and control treatments ( Figure 5 ).

For example, in drought stress response, genes involved in “membrane,” “abiotic stress stimulus,” “oxidoreductase activity,” “response to abiotic stress,” “response to stress,” “ADP metabolic process,” and “oxidation-reduction process,” were mainly enriched in cluster D-III, which exhibited an increasing trend from 12 to 36 h, indicating that membrane biosynthesis, ADP metabolic process and oxidoreductase activity pathways are enhanced in response to drought stress ( Figure S1 ).

The two loci have high LOD values and may be significant trait-associated QTNs with breeding potential ( Supplementary Figure S3 ).

The correlation between the expressions of these two genes was extremely significant ( Table 1 ).

Globally, the majority of countries are facing a decreasing trend of NUE (from 68% to 47%) over a period of five to six decades (1960–1970) ( Lassaletta et al., 2014 ).

ramosissima in the 200 mM NaCl and 200 mM NaCl + 10 mM KCl groups showed an increasing trend with time when exogenous sources were applied under NaCl stress for 48 and 168 h ( Figure 2 ).

Under the stress of NaCl and with the treatment of exogenous K + for 48h and 168h ( Table 1 ), 4 DEGs including Unigene0022482 , Unigene0074194 , Unigene0104234 and Unigene0002762 in SOD activity, showed a trend of first decreasing and then increasing, and the expression level of Unigene0035818 had been continuously increasing. 16 DEGs including Unigene0002490 , Unigene0004177 , Unigene0016209, Unigene0022473 , Unigene0033992 , Unigene0009260 , Unigene0034947 , Unigene0053707 , Unigene0068179 , Unigene0076259 , Unigene0080006 , Unigene0084405 , Unigene0084406 , Unigene0087484 , Unigene0089435 and Unigene0102899 in POD activity showed a trend of first decreasing and then increasing.
