“…applications, which means that paclobutrazol applications might increase the amount of dry substance allocated to the pods rather than to the leaves of the peanut and increased the peanut yield for all treatments in our study. These results are consistent with the conclusions previously drawn by Kuai et al (2017) and Esmaielpour et al (2011).…”

“…In addition, paclobutrazol, which is one of the most potent plant growth retardants and is reported to decrease stem length (Rademacher 1990), reorient the distribution of assimilations to adjust the source-sink balance (Kuai et al 2017) and increase peanut seed yields (Senoo and Isoda 2003), has been used in peanut production for many years. Its triazoles alter the balance of important plant hormones, including gibberellic acid, abscisic acid and cytokinins (Upreti et al 2013).…”

Background: Peanut yields are affected by plant density and chemical controls. Methods: A field experiment was conducted in Southern China to investigate the effects of population density and paclobutrazol applications on the growth and yield of peanuts with monoseeding and double seeding patterns. Result: Paclobutrazol application could improve peanut yields. The highest peanut yields were observed with 250 mg L-1 paclobutrazol and a plant density of 235 410 plants ha-1, with the monoseeding pattern. Our results suggest that monoseeding and paclobutrazol could be applied to enhance peanut yields in Southern China.

“…Moreover, it results in higher photosynthate production in leaves that accumulate on the stem instead of being transferred to roots, resulting in taller plants and increased risk of lodging (Kuai et al . 2017).

Lodging in maize results in grain yield reduction. This experiment investigated the effects of different application rates of the growth retardant, uniconazole (UCZ), and nitrogen (N) on medium and high maize population densities on lodging resistance and yield. UCZ was applied to maize seeds at concentrations of 0 (U0) and 25 (U25) mg kg−1, and three different N application rates, 0 (N0), 150 (N150) and 225 (N225) kg ha−1, at plant densities of 75,000 (D1) and 105,000 plants ha−1 (D2). UCZ application, different N rates and plant population density affected the lodging resistance and yield attributes of maize. The diameter, plumpness, cortex penetration and bending strengths of the internodes were enhanced with UCZ and N application at medium and high plant density, where maximum values were obtained with U25N150D1. Internode length increased in the high‐density population and higher N rate, whereas UCZ reduced internode length, where maximum internode length was obtained with U0N225D2. Plant height, centre of gravity height, ear and height above ear‐bearing node were higher with the high N rate, while UCZ reduced it significantly. UCZ, N rate and plant density enhanced lignin accumulation in the third internode and ear‐bearing internode, where maximum values were obtained with U25N150D1. Yield and yield attributes were also improved by UCZ, N rate and population density. Treatment with U25N150D2 significantly improved grain yield of maize compared with the other treatments.

“…Specifically, it leads to a sharp decrease in the efficiency of mechanical harvesting and significantly increases the loss of seeds in the process, thus affecting the yield and notably reducing the cost‐effectiveness of growing rapeseed. After lodging, the yield of rapeseed can be reduced in varying degrees (Kendall et al., 2017; Khan et al., 2018; Kuai et al., ,2015, 2017), and the quality of seeds is reduced, with lower content of oil, linoleic and linolenic acids as well as higher content of erucic and sinapic acids (Khan et al., 2018). To optimise planting density and row spacing is important for integrating high yield with lodging resistance.…”

Lodging is an important factor that restricts the yield of rapeseed and the mechanical harvesting. To explore agricultural practise and mechanisms that can synergistically improve the rapeseed yield and lodging resistance, a conventional plant type HZ 62 was selected in 2016–2017, and HZ 62 and an erect‐leaf type 1,301 were grown in 2017–2018. The planting density was set as main plots at 15 × 104 plants ha1 (D1), 30 × 104 plants ha‐1 (D2) and 45 × 104 plants ha−1 (D3), with the row spacing as sub‐plots of 15 cm (R15), 25 cm (R25) and 35 cm (R35). The results showed that with increased density and narrowed row spacing, the radiation utilisation efficiency (RUE) of the population and seed yield were greatly increased. Compared with that at D1R25, the yield of HZ 62 at D3R15 was increased by 19.00% and 22.53%, respectively, in 2016–2017 and 2017–2018, whereas the yield of 1,301 rose by 31.98%. The influence of the RUE on the seed yield reached the peak at flowering stage. With increased planting density and narrowed row spacing, the lodging index of HZ 62 declined. The lodging index of 1,301 was increased with higher density and declined with narrowed row spacing. Compared with D1R25, the averaged lodging index across different parts of HZ 62 at D3R15 declined by 15.03% and 10.80%, respectively, in 2016–2017 and 2017–2018, and that of 1,301 was increased by 25.47%. Compared with D1R25, the stem proteomics during the flowering stage showed the expression of photosynthesis‐related proteins (A0A078FHG9, A0A078JZM9 and A0A078JQI2) up‐regulated, that consistent with Rubisco, SPS and FBPase activities; proteins related to phenylpropanes metabolism, A0A078IWR4 of HZ 62 and A0A078JWZ9 of 1,301 increased that consistent with POD activity, which resulted in more sucrose, starch and lignin in the stem at D3R15. Moreover, the protein related to cellulose synthesis (A0A078I4D9), the activity of β‐1,3‐glucanase and content of cellulose in the stem were up‐regulated in HZ 62 but down‐regulated in 1,301, contrary to the variation in the stem lodging index. The cellulose synthesis differed between the varieties in different treatment combinations of planting density and row spacing. This was the key process by which planting density and row spacing influence the lodging of rapeseed varieties with varied plant architecture.
