However, under a severe water deficiency, their yields will show a decreasing trend [ 17 ].

Ornamental plants, including cut flowers, foliage, and live plants, showed a positive trend in export growth, which led to an aggregate world value of around EUR 18 billion in 2020 [ 80 ].

According to the tuber expansion parameters ( Table 2 ), the initial growth potential of the tubers (R 0 ) exhibited a decreasing trend followed by an increasing trend.

A significant or highly significant positive correlation was observed between the tuber expansion rate and both the yield and NUE (R 2 = 0.654*~973**).

In low nitrogen treatments (N0 and N100), the N A demonstrated a decreasing trend over time, while in high nitrogen treatments (N300 and N400), it showcased an ascending and then descending pattern, reaching its zenith on the 30th day at 3.78–5.63 μg cm –2 .

Moreover, CS22, CS49, CS50, CS34, UA48, and CS23 displayed a decreasing trend in reducing Palmer amaranth height from 14 to 21 days after establishment.

Above-Ground Dry Matter The spring maize above-ground dry matter accumulation showed an increasing trend with plant growth ( Figure 4 ).

However, nitrogen fertilizer’s agronomic utilization efficiency and partial productivity showed a decreasing trend.

The above-ground and root biomass showed a trend of increasing and then decreasing with the increase in nitrogen application level.

Furthermore, it is notable in these three maps that there was an apparent trend in the distribution of Ψstem across the vineyard, as seen in the ISR values. 4.

In the late-season stage (days 225–240), NDRE values showed a decreasing trend due to the gradual depletion of crop moisture.

Generally, with an increase in the stress period, the plant chlorophyll a, chlorophyll b, and carotenoid contents showed a trend of decrease, while the total anthocyanin and phenolic contents presented an overall tendency to increase ( Figure 4 ).

In the overall view of a decreasing trend, the results are still illustrative.

Under salt stress, the Chl content of the five lines showed an increasing trend ( Figure 7 B), while Pn, Fv/Fm, Gs, Ci, and Tr gradually decreased.

Initially, the starch content exhibited an increasing trend followed by a decreasing trend before ultimately showing growth.

The water content of the soybean leaves treated with W1 showed a decreasing trend within 6–9 h, an increasing and then decreasing trend during 9–48 h, and a significant decrease at 48 h.

Upon entering strong stress, the CAT activity in the W0.2 and W1 treatments exhibited a decreasing trend in the first 24 h and then an increasing trend.

The shedding rate showed a trend of rapid increase, and then followed by changes in both decrease and increase. 3.2.1.

With the increase in growth days, the proportion of flowers, buds and bolls showed an increasing trend ( Figure 8 c), while the proportions of leaves and stems showed a decreasing trend ( Figure 8 a,b).

After planting Festuca arundinacea and Poa pratensis , the soil total nitrogen and available phosphorus contents showed a trend of increasing first and then decreasing with the increase in the bacterial liquid concentration, but they were all higher than those in the control treatment.

With the increase in corn straw mulching, the Pn , Tr , and Gs of foxtail millet leaves showed a trend of first increasing and then decreasing, while the Ci first decreased and increased.

As the planting density increases, the amount of dry matter accumulation per maize plant shows a decreasing trend [ 23 ].

In the VT period, with the increase in the planting density, the inhibitory effect of the selenium fertilizer on ear height showed an increasing trend: for example, under the D1 and D3 planting densities in 2022, Se3 treatment decreased the ear height by 0.71% and 4.74%, respectively, compared with the Se0 treatment.

Compared with no treatment, the correlation between spectral index and potato LCC and the prediction accuracy of the model showed a trend of decreasing after initial growth with the increase in differential order.

Similar to the conclusions presented in [ 32 ], a significant decrease was seen with all treatments at 14:00, but overall, the photosynthetic parameters showed an increasing trend, with bimodal peaks.
