“…In the present study, at the time of higher temperatures when the experiment took place, the internodes shortened at the highest GA concentration used. This effect is opposite to that reported in the literature for most crops (Zhang et al, 2020;Davies, 2010). The internode elongation observed in the mini-stumps treated in July is the typical action expected when GA is applied, since the use of this regulator tends to favor internode elongation (Davies, 2010).…”

The viability of the mini-cutting technique requires seedling regrowth ability and continuous propagule production. It is hypothesized that the application of gibberellic acid (GA) can stimulate vegetation and increase the production of mini-cuttings. The aim of this study was to increase the mini-cutting yield of Psidium guajava (L.) × Psidium guineense (Sw.) (‘BRS Guaraçá’) as a function of foliar application of GA and season of the year. The experiment was laid out in a randomized-block design with split-plots in time, in which the plots consisted of different GA concentrations applied (0, 50, 100, 150 and 200 mg L-1) and the subplots were represented by two application periods or seasons (summer and winter). Four replicates were used, with two plants per plot. After the seedlings were topped, GA was applied at different concentrations and the emerged shoots were evaluated over 30 days. Mini-stump yield was assessed by collecting and evaluating the potential number of mini-cuttings. Shoot length and mini-stump yield increased linearly with the increasing GA concentrations during the summer. In the winter, this response was quadratic, with optimal concentrations estimated at 65.3 mg L-1 for shoot length and 76 mg L-1 for mini-stump yield. The GA concentration of 200 mg L-1 provided shorter internodes in the summer, whereas in the winter the use of GA did not interfere with this trait. The increasing applications of GA induced a linear increase in stem diameter at both seasons of the year. Gibberellic acid did not interfere with the rooting of the mini-cuttings. The highest rooting percentage occurred in the summer, with an average of 95%. In the winter, this value was 77.2%, demonstrating that mini-cuttings are a promising technique for ‘BRS Guaraçá’. Foliar spraying of GA promoted an increase in mini-cutting production, without interfering with their rooting.

“…Canopy height, cob height and culm diameter are important determinants for lodging resistance of maize plants (Kamran, et al, 2018a). Although lodging was no problem in our experiment, as the containers were placed in a vegetation hall, in the field heavy rain showers and stormy weather conditions can cause breaking of maize stalks leading to considerable grain yield losses (Xue et al, 2016;Zhang et al, 2020). Smaller, growth-regulated plants with lower inserted cobs and thicker culms were characterized by a higher mechanical strength, were thus less susceptible to these adverse weather conditions and showed improved lodging resistance (Kamran, et al, 2018aa;Xu et al, 2017;Zhang et al, 2020).…”

“…Increasing the planting density and N fertilizer application are very effective agronomic strategies for raising the yield of modern maize cultivars, but high plant density and excessive N application have led to thinner and taller stalks, which has increased the lodging risk (Ciampitti & Vyn, 2012). Lodging is a major constraint limiting yield and quality of grain production, and it can account for up to 30% of annual losses of maize grain yield (Xue et al., 2016; Zhang et al., 2020).…”

Soil salinization threatens sustainable agricultural production and ecological balance in many parts of the world. Therefore, to breed plants with salt tolerance and discover the resistance genes are essential for enhancing salt tolerance adaptation. We studied phenotypic, physiological characteristics, and digital RNA sequencing of two broomcorn millet cultivars (salt tolerant cultivar, ST 47; salt sensitive cultivar, SS 212), stressed by 1% NaCl (w/w; 170 mM) for 0, 12 hr, 1, 3, 7 days and subsequent rewatering 7 days (RW 7 days). By comparative phenotype and physiology analysis we suggest ST 47 showed greater salt tolerance and faster recovery after re-watering than SS 212, and lower Na + contents and higher K + /Na + ratio. Digital RNA sequencing analysis suggested 6,878 and 1,940 differentially expressed genes (DEGs) were detected in ST 47 at 12 hr (vs. 0 hr) and RW 7 days (vs. 0 hr), respectively, whereas 7,246 and 5,375 DEGs were identified in SS 212. DEG functional enrichments suggested ST 47 exhibited better regulation of phenylpropanoid biosynthesis, carbon metabolism, and auxin and gibberellin signal transduction in response to salt stress via enhancing the cell wall biosynthesis. Furthermore, ionic stress signaling analysis proposed ST 47 better regulation of Na + distribution in response to salt stress. These results provide valuable information for improving salinity tolerance in plants and studying the function of candidate genes governing salt tolerance in broomcorn millet.
