Overall, the root–shoot ratio demonstrated a decreasing trend during the transition from HC to SC.

A highly significant negative correlation was also detected between BT and ST, FW, FD; SSC and FSI, FW, FL, FD; and FD and FSI ( Supplementary Table 4 ; Figure 3 ).

The relative expression trends of the Clcsm gene ( Cla97C06G126680 ) and ClMYB36 gene ( Cla97C10G203210 ) were highly significant in the clear stripe margin pattern line (slb, P 1 ) than the blurred stripe margin pattern line (GWAS-38, P 2 ); the ClAPRR5 gene ( Cla97C01G000070 ) showed highly significant expression in the blurred stripe margin pattern line (GWAS-38, P 2 ); the other seven genes ( ClMYB20 , ClMYB10 , ClRAX3 , ClIPN2 , ClEFM , ClAPRR2 , and ClKAN2 ) did not show any significant differences in expression level between the comparative parental lines.

natans The chlorophyll (a+b) of different light treatments had different trends, the 5% light treatment had an increasing trend, which increased by 26.7% on the 60th day compared with the 12th day, while the 20% light treatment had a decreasing trend, and the 60th day decreased by 38% compared with the 12th day.

With the increase of experimental time, the root/leaf ratio of the four groups under 5% light treatment showed a decreasing trend.

At 7 DAS, root lengths significantly increased when seedlings were exposed to 0.25 mg/ml WBC450, and an increasing trend was observed at 0.5 mg/ml WBC450.

Subsequently, with the increase of calcium concentration, the TC, TN, TP, and TK contents in each organ and the whole plant showed a decreasing trend, and when the calcium concentration reached 400 mg·kg -1 , they all significantly decreased compared to the control without calcium (except for the TP content in stems) ( p < 0.05).

The changing trends of C:N and C:P ratios in Pinus tabuliformis seedlings in this study indicate that as calcium concentration increases, the growth rate of Pinus tabuliformis seedling roots initially slows down and then accelerates, showing an increasing trend when calcium concentration reaches 400 mg·kg -1 .

3 Results 3.1 The trend and stability of GPP As shown in Figure 4A , GPP had a significant trend from 1982 to 2019, with an increased rate of 3.3892 gC m −2 year −1 .

Our findings revealed the following: (1) GPP demonstrated an increased trend with lower stability in Eastern regions, whereas a decreasing trend with higher stability was observed in Western and Southwest China.

Particularly in areas impacted by the simultaneous implementation of the five projects, GPP showed an increasing trend (81.97%) and lower sensitivity (3.98%) to climate change.

polycephalum are of great importance, especially when a clear trend that its habitat shifts to the north was observed.

Under B toxicity conditions, the BCFs of B in different organs showed a trend of BCF NL+F > BCF NL−F > BCF OL+F > BCF OL−F > BCF peel and BCF pulp regardless of soil total B and soil water-soluble B, and there is no difference between BCF peel and BCF pulp ( Figure 10 ).

In our studies, TP and TC were in greater quantity on day 0, while they were lowest in the control treatment, so we can assume that in the control treatment, they were lowest due to the uptake by the plant, which showed an increasing trend with the decreasing size of microplastics.

As the stubble height decreases, the NSC content shows a decreasing trend ( Lee et al., 2008 ).

There was a highly significant negative correlation between regeneration ability and stubble C/N, with an R 2 of 0.6774.

The experimental years showed the same trend of change, both increasing with irrigation or precipitation replenishment and showing a decreasing trend with garlic growth and continuation ( Figure 6 ).

In addition with potato growth, the DW of potato plants showed an increasing trend, with a consistent trend across three years ( Figure 1 ).

solani showed a decreasing trend.

solani showed a trend of increasing first and then decreasing, reaching the maximum at 60 days.

In addition, from 1989 onwards, the AGC density in the sample site showed an increasing trend from year to year.

Pearson correlation analysis showed that the increase in yield was accompanied by the decrease in N 2 O emission, and there was a highly significant negative correlation between yield and N 2 O emission ( R = − 0.64), and there was a significant negative correlation between RE N and N 2 O emission ( R = − 0.37), with the higher the RE N , the lower the N 2 O emission.

The emission peaks basically showed a trend of ST > CF > PM > BR, except for the emission peak after fertilization in wheat season, which showed a trend of PM > CF > ST > BR.

Other studies show that the application of alkaline biochar does not increase the pH of alkaline soils; instead, it may induce a decreasing trend in pH, especially with higher rates of biochar application ( Zhang and Liu, 2012 ).

Overall, we found a clear trend of betalain contents with their visible pigmentation levels compared among tissues.
