“…The performance of numerous agricultural plants was improved using boron fertilizers, most importantly in terms of yield, but also in terms of quality and certain physiological parameters, e.g., water management and chlorophyll content. Given the narrow range between deficiency and toxicity, the dosage of the added boron should be carefully adjusted for each application [164][165][166][167][168][169][170][171].…”

Boron is an essential plant micronutrient taken up via the roots mostly in the form of boric acid. Its important role in plant metabolism involves the stabilization of molecules with cis-diol groups. The element is involved in the cell wall and membrane structure and functioning; therefore, it participates in numerous ion, metabolite, and hormone transport reactions. Boron has an extremely narrow range between deficiency and toxicity, and inadequate boron supply exhibits a detrimental effect on the yield of agricultural plants. The deficiency problem can be solved by fertilization, whereas soil boron toxicity can be ameliorated using various procedures; however, these approaches are costly and time-consuming, and they often show temporary effects. Plant species, as well as the genotypes within the species, dramatically differ in terms of boron requirements; thus, the available soil boron which is deficient for one crop may exhibit toxic effects on another. The widely documented intraspecies genetic variability regarding boron utilization efficiency and toxicity tolerance, together with the knowledge of the physiology and genetics of boron, should result in the development of efficient and tolerant varieties that may represent a long-term sustainable solution for the problem of inadequate or excess boron supply.

“…Cultivars of indeterminate growth such as the one used in this study present a lower proportion of the vegetative phase (33.4%) than the cultivars of determined growth (42%), a fact associated with the overlap of the vegetative and reproductive phases and, consequently, their early flowering (ZANON et al 2015) which indicates a higher proportion of the growth cycle in the reproductive phase. Thus, as part of the fertilization was performed in V4, the physiological activities of the soybean plant were enhanced, as in the case of the photosynthetic rate and the efficient use of water, as reported by FUJIYAMA et al (2019). On the other hand, the applications in R1 and R3 favored the supply of B to the reproductive phase, which presented a higher proportion of the total cycle in the reproductive period.…”

A soja é uma das culturas anuais mais exigentes em boro (B), no entanto, existe uma divergência em relação sobre qual melhor estádio fenológico para efetuar essa aplicação via foliar. Logo, o objetivo do presente trabalho foi avaliar a influência de diferentes épocas de aplicação foliar de B, com e sem parcelamento no florescimento, produtividade e componentes da produção da soja. Para tal, foi realizado um experimento em campo, o delineamento experimental utilizado foi em blocos ao acaso, com sete épocas de aplicações foliares de B (testemunha, 100% 15 V4, 100% R1, 100% R3, 50% V4 + 50% R1, 50% V4 + 50% R3 e 50% R1 + 50% R3) e quatro repetições, totalizando 28 parcelas experimentais. Foram analisados o número de flores, número de canivete, teor de B nas plantas, peso de 1000 grãos (g) e a produtividade. O maior teor B foi observado com aplicações nos estádios V4 (50%) + R1 (50%) e V4 (50%) + R3 (50%) isto é, parte no estádio vegetativo e parte no estádio reprodutivo. A aplicação de B não resultou em diferença significativa em relação ao número de inflorescências por planta. Não houve efeito significativo das épocas de aplicação foliar de B para a variável de número de vagens por planta, número de inflorescências e produtividade. Para peso de 1000 grãos (g) foram encontrados maiores valores em V4, R1 e R3 e na testemunha. Portanto, a aplicação foliar de boro nos estádios V4 (50%) + R1 (50%) e V4 (50%) + R3 (50%) aumentou os níveis de B na planta, enquanto em R1+R3 proporcionou o maior número de canivetes. No entanto, não houve efeito da aplicação de boro para a produtividade de grãos independente da época de aplicação.

“…During the measurement, photosynthetically active radiation (PAR) was 780 μmol m −2 s −1 and atmospheric CO 2 concentration was 390 ± 5 μmol mol −1 (i.e., at light saturating intensity). Water use efficiency (WUE) was calculated as ratio of Pn to E and intrinsic water use efficiency (IWUE) was calculated by dividing Pn with Gs (Fujiyama et al, 2019).…”

“…Three of the ATP synthases in chloroplasts can be regulated by MT and it also improves the functioning of photosystem I and photosystem II during light and dark cycles (Arnao et al, 2015). These MDA and H 2 O 2 are considered oxidative stress markers which are linked to membrane leakage (Evelin et al, 2019;Fileccia et al, 2017).…”

Salt stress is an alarming abiotic stress that reduces mustard growth and yield. To attenuate salt toxicity effects, plant growth‐promoting rhizobacteria (PGPR) offers a sustainable approach. Among the various PGPR, Pseudomonas fluorescens (P. fluorescens NAIMCC‐B‐00340) was chosen for its salt tolerance (at 100 mM NaCl) and for exhibiting various growth‐promoting activities. Notably, P. fluorescens can produce auxin, which plays a role in melatonin (MT) synthesis. Melatonin is a pleiotropic molecule that acts as an antioxidant to scavenge reactive oxygen species (ROS), resulting in stress reduction. Owing to the individual role of PGPR and MT in salt tolerance, and their casual nexus, their domino effect was investigated in Indian mustard under salt stress. The synergistic action of P. fluorescens and MT under salt stress conditions was found to enhance the activity of antioxidative enzymes and proline content as well as promote the production of secondary metabolites. This led to reduced oxidative stress following effective ROS scavenging, maintained photosynthesis, and improved growth. In mustard plants treated with MT and P. fluorescens under salt stress, eight flavonoids showed significant increase. Kaempferol and cyanidin showed the highest concentrations and are reported to act as antioxidants with protective functions under stress. Thus, we can anticipate that strategies involved in their enhancement could provide a better adaptive solution to salt toxicity in mustard plants.In conclusion, the combination of P. fluorescens and MT affected antioxidant metabolism and flavonoid profile that could be used to mitigate salt‐induced stress and bolster plant resilience.
