“…This can be a natural survival strategy in unfavorable situations (stress), which optimizes the chances of perpetuating the species in the cultivation environment, as discussed for other species ( Marcos et al, 2018a , b ). A similar proposal was explored in tomato ( Nogueira et al, 2021 ), and it was found that seeds produced in a stressful environment gave rise to seedlings with adaptive enhancement in chlorophyll fluorescence. Thus, considering the notable connection of chlorophyll fluorescence found ( Figure 11A ) with photosynthesis in plant organisms ( Valcke, 2021 ), the idea that peanut seedlings signaled compensatory adjustments in photosynthetic capacity in response to seed deterioration induced by artificial aging (high temperature and high RH) was proposed.…”

Seeds of high physiological quality are defined by their superior germination capacity and uniform seedling establishment. Here, it was investigated whether multispectral images combined with machine learning models can efficiently categorize the quality of peanut seedlots. The seed quality from seven lots was assessed traditionally (seed weight, water content, germination, and vigor) and by multispectral images (area, length, width, brightness, chlorophyll fluorescence, anthocyanin, and reflectance: 365 to 970 nm). Seedlings from the seeds of each lot were evaluated for their photosynthetic capacity (fluorescence and chlorophyll index, F0, Fm, and Fv/Fm) and stress indices (anthocyanin and NDVI). Artificial intelligence features (QDA method) applied to the data extracted from the seed images categorized lots with high and low quality. Higher levels of anthocyanin were found in the leaves of seedlings from low quality seeds. Therefore, this information is promising since the initial behavior of the seedlings reflected the quality of the seeds. The existence of new markers that effectively screen peanut seed quality was confirmed. The combination of physical properties (area, length, width, and coat brightness), pigments (chlorophyll fluorescence and anthocyanin), and light reflectance (660, 690, and 780 nm), is highly efficient to identify peanut seedlots with superior quality (98% accuracy).

“…A potential memory effect through signals generated or processed in the cutting and/or root cannot be excluded either. It should be supplemented here that a recent study also provides evidence suggestive of the generation and/or process of signals in the root involved in transgenerational effects of oxidative stress, specifically by Cd (Nogueira et al 2021). Therefore, further experimentation is needed to reveal whether carry-over and/or memory effects of O 3 are primarily driven by roots.…”

Ethylenediurea (EDU) spray effects on willows (Salix sachalinensis F. Schmid) grown in ambient or ozone-enriched air: implications for renewable biomass production

et al. 2021

Ground-level ozone (O3) is a widespread air pollutant causing extensive injuries in plants. However, its effects on perennial energy crops remain poorly understood due to technical difficulties in cultivating fast-growing shrubs for biomass production under O3 treatment on the field. Here we present the results of a two-year evaluation in the framework of which willow (Salix sachalinensis F. Schmid) shrubs were exposed to ambient (AOZ) or elevated (EOZ) O3 in two successive growing seasons (2014, 2015) and treated with 0 (EDU0) or 400 mg L−1 (EDU400) ethylenediurea spray in the second growing season. In 2014, EOZ altered the chemical composition of both top young and fallen leaves, and a novel mechanism of decreasing Mg in fallen leaves while highly enriching it in young top leaves was revealed in shrubs exposed to EOZ. In 2015, EDU400 alleviated EOZ-induced decreases in leaf fresh mass to dry mass ratio (FM/DM) and leaf mass per area (LMA). While EDU400 protected against EOZ-induced suppression of the maximum rate at which leaves can fix carbon (Amax) in O3-asymptomatic leaves, it did not alleviate EOZ-induced suppression of the maximum rates of carboxylation (VCmax) and electron transport (Jmax) and chlorophylls a, b, and a + b in the same type of leaves. In O3-symptomatic leaves, however, EDU400 alleviated EOZ-induced suppression of chlorophylls a and a + b, indicating different mode of action of EDU between O3-asymptomatic and O3-symptomatic leaves. Extensive herbivory occurred only in AOZ-exposed plants, leading to suppressed biomass production, while EOZ also led to a similar suppression of biomass production (EDU0 × EOZ vs. EDU400 × EOZ). In 2016, carry-over effects were also evaluated following cropping and transplantation into new ambient plots. Effects of EOZ in the preceding growing seasons extended to the third growing season in the form of suppressed ratoon biomass production, indicating carry-over effect of EOZ. Although EDU400 protected against EOZ-induced suppression of biomass production when applied in 2015, there was no carry-over effect of EDU in the absence of EDU treatment in 2016. The results of this study provide novel mechanistic understandings of O3 and EDU modes of action and can enlighten cultivation of willow as energy crop.

“…Para isso, podemos utilizar nos estudos a enxertia recíproca e análises das estruturas radiculares que auxiliam na elucidação dos mecanismos responsáveis (XIN et al, 2013). O genótipo que mais acumulou Cd nas folhas e no caule quando usado como copa, foi o genótipo USP17, sendo este o genótipo considerado uma das principais referências de susceptibilidade ao Cd em trabalhos anteriores (BORGES et al, 2018;CARVALHO et al, 2018aCARVALHO et al, , 2019PIOTTO et al, 2018;NOGUEIRA et al, 2021). Já no caso de acúmulo de metal das folhas e translocação para a parte aérea das plantas, provavelmente é regido por mecanismos similares ou talvez complementares à tolerância, uma vez que nesta mesma combinação foi constatada menor concentração de Cd nas folhas, como provável resultado da união de mecanismos de redução de absorção e transporte deste metal entre os genótipos da copa e porta-enxerto.…”

Todos os genótipos foram usados como porta-enxertos e copas, em todas as combinações possíveis, formando trinta combinações de copa e porta-enxerto e mais seis enxertias de cada genótipo sobre ele mesmo, totalizando 36 tratamentos.…”

“…. Assim, genótipos de tomateiros têm sido estudados para elucidar os mecanismos que caracterizam a tolerância ao Cd para o desenvolvimento de programas de melhoramento de plantas(NOGUEIRA et al, 2021). Para isso, é necessário identificar genótipos de tomateiros tolerantes ao Cd e investigar as vias que reduzem a translocação do Cd da raiz para a parte aérea das plantas, resultando na diminuição dos teores do Cd nos frutos.…”
