“…and Serratia marcescens . Stimulation of marigold flower production by Bacillus subtilis BEB‐13 has also been reported, thus supporting the hypothesis that QST713 plays a role in the promoting plant flowering. Our results also showed that CHT‐TPF was produced in greater quantity (17%), compared to control‐PF (Fig.…”

BACKGROUND: The production of fruit and vegetables rich in health-promoting components in an eco-friendly context represents the winning answer to the world population demand for food. In this study, the effects of different treatments on the yield and fruit chemical characteristics of tomato (Solanum lycopersicum L.) are reported. The treatments included three inducers of plant defence responses (chitosan, Trichoderma harzianum T-22 and Bacillus subtilis QST713) applied alone or before Cucumber mosaic virus infection. Fruit production and antioxidant compounds were investigated by ultrahigh-performance liquid chromatography (UHPLC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). RESULTS: Compared to control fruit harvested from untreated and healthy plants, treatment with QST713 increased the fruit number. Furthermore, plant treatments with T22, QST713 and chitosan alone enhanced fruit carotenoids (lutein and -carotene), ascorbic acid and phenolic acids (caffeoyl glucoside and p-coumaroyl glucoside). In parallel, compared to fruit harvested from only CMV-infected plants, treatments with T22, QST713 and chitosan before CMV enhanced fruit ascorbic acid and flavonoids (quercetin 3-O-xylosyl-rutinoside and rutin). CONCLUSION: Antioxidant compounds of tomato fruit can increase with the application of the plant defence inducers, thus protecting both the consumer and plant health. Statistical data analysisData normal distribution was tested using the Shapiro-Wilk test (P ≤ 0.05) and homoscedasticity using Bartlett's test (P ≤ 0.05). Data were analysed by one-way analysis of variance (ANOVA), parametric and non-parametric, performing Tukey's HSD and Kruskal-Wallis test, respectively. Statistical data analyses were carried out using RStudio software, version 1.0.136 (Integrated Development for R; Boston, MA, USA).J Sci Food Agric 2019; 99: 5541-5549

“…Bacillus subtilis and Glomus sp. increase total flower number of Tagetes erecta plants when cultivated in a sandy loam soil (Flores et al, 2007), and inoculation with Pseudomonas putida and P. fluorescens strains increases plant size and fl ower number of Pelargonium peltatum, Chrysanthemum sp., and Dahlia variabilis plants cultivated under greenhouse conditions (Göre and Altin, 2006). In addition, application of the nitrogen-fixing Azospirillum lipoferum and the phosphate-solubilizing Bacillus polymxa increases the flower number of Petunia × hybrida plants grown under field conditions with different levels of fertility (Hoda and Mona, 2014).…”

Identification of Pseudomonas Spp. That Increase Ornamental Crop Quality During Abiotic Stress

et al. 2020

The sustainability of ornamental crop production is of increasing concern to both producers and consumers. As resources become more limited, it is important for greenhouse growers to reduce production inputs such as water and chemical fertilizers, without sacrificing crop quality. Plant growth promoting rhizobacteria (PGPR) can stimulate plant growth under resource-limiting conditions by enhancing tolerance to abiotic stress and increasing nutrient availability, uptake, and assimilation. PGPR are beneficial bacteria that colonize the rhizosphere, the narrow zone of soil in the vicinity of the roots that is influenced by root exudates. In this study, in vitro experiments were utilized to screen a collection of 44 Pseudomonas strains for their ability to withstand osmotic stress. A high-throughput greenhouse experiment was then utilized to evaluate selected strains for their ability to stimulate plant growth under resource-limiting conditions when applied to ornamental crop production systems. The development of a highthroughput greenhouse trial identified two pseudomonads, P. poae 29G9 and P. fluorescens 90F12-2, that increased petunia flower number and plant biomass under drought and low-nutrient conditions. These two strains were validated in a productionscale experiment to evaluate the effects on growth promotion of three economically important crops: Petunia × hybrida, Impatiens walleriana, and Viola × wittrockiana. Plants treated with the two bacteria strains had greater shoot biomass than untreated control plants when grown under low-nutrient conditions and after recovery from drought stress. Bacteria treatment resulted in increased flower numbers in drought-stressed P. hybrida and I. walleriana. In addition, bacteria-treated plants grown under low-nutrient conditions had higher leaf nutrient content compared to the untreated plants. Collectively, these results show that the combination of in vitro and greenhouse experiments can efficiently identify beneficial Pseudomonas strains that increase the quality of ornamental crops grown under resource-limiting conditions.

“…Additionally, PGPR from the genus Bacillus have been shown to accelerate time to flowering for crops such as banana ( Musa acuminata cv. “Berangan”), marigold ( Tagetes erecta L.) and carnation ( Dianthus carophyllus L.) (Mia et al, 2005; Flores et al, 2007; Kumar et al, 2014). Achieving flowering in a shorter timespan would reduce the time to harvest for each growth cycle to help growers attain a higher number of harvests per year.…”

Closing the Yield Gap for Cannabis: A Meta-Analysis of Factors Determining Cannabis Yield

et al. 2019

View full text Add to dashboard Cite

Until recently, the commercial production of Cannabis sativa was restricted to varieties that yielded high-quality fiber while producing low levels of the psychoactive cannabinoid tetrahydrocannabinol (THC). In the last few years, a number of jurisdictions have legalized the production of medical and/or recreational cannabis with higher levels of THC, and other jurisdictions seem poised to follow suit. Consequently, demand for industrial-scale production of high yield cannabis with consistent cannabinoid profiles is expected to increase. In this paper we highlight that currently, projected annual production of cannabis is based largely on facility size, not yield per square meter. This meta-analysis of cannabis yields reported in scientific literature aimed to identify the main factors contributing to cannabis yield per plant, per square meter, and per W of lighting electricity. In line with previous research we found that variety, plant density, light intensity and fertilization influence cannabis yield and cannabinoid content; we also identified pot size, light type and duration of the flowering period as predictors of yield and THC accumulation. We provide insight into the critical role of light intensity, quality, and photoperiod in determining cannabis yields, with particular focus on the potential for light-emitting diodes (LEDs) to improve growth and reduce energy requirements. We propose that the vast amount of genomics data currently available for cannabis can be used to better understand the effect of genotype on yield. Finally, we describe diversification that is likely to emerge in cannabis growing systems and examine the potential role of plant-growth promoting rhizobacteria (PGPR) for growth promotion, regulation of cannabinoid biosynthesis, and biocontrol.
