“…In summary, the application of humic acid appears to be a viable alternative for the production of papaya seedlings using brackish water for irrigation, provided that the increases in growth and gas exchange are directly linked to plant productivity (Ramos et al, 2021;Kumar et al, 2022). These findings contribute to broadening our knowledge of the physiological aspects of C. papaya growth with saline water irrigation as well as the practical application of humic acid to improve papaya seedling production under salt stress.…”

Salinity is one of the major obstacles to agriculture in semi-arid regions, as it affects the physiological processes, growth, and yield of numerous crops. Hence, the application of salt stress attenuators is of paramount importance, as it enables the use of saline water for agricultural purposes. Among these, humic acid promotes the growth as well as water and nutrient uptake of plants. To this end, the present study evaluated the effects of humic acid on the growth and physiology of Carica papaya seedlings irrigated with saline water. The experiment followed the randomized block design with five levels of electrical conductivity (0.5, 1.15, 2.75, 4.35, and 5.0 dS m-1) and five concentrations of humic acid (0.5, 0.94, 2.0, 3.06, and 3.5 mL L-1). Growth, gas exchange, chlorophyll content, and chlorophyll a fluorescence were evaluated. Irrigation with 4.9 dS m-1 water and application of 3.05 mL L-1 humic acid promoted the growth of papaya seedlings. Irrigation with high-salinity water (4.96 and 3.09 dS m-1) coupled with the application of 3.05 and 2.21 mL L-1 humic acid increased internal CO2 concentration, transpiration, instantaneous water use efficiency, carboxylation efficiency, and chlorophyll b content. Overall, humic acid (3.5 mL L-1) attenuated the deleterious effects of salt stress, promoting the growth and improving the performance of papaya seedlings under moderate salinity (4 dS m-1).

“…Os acessos com maior altura (75 e 91) ou maior largura (49 e 75) são desejáveis, visto que essas características estão diretamente correlacionadas com a produtividade. (RAMOS et al, 2021;KUMAR et al, 2022). Além disso, plantas de maior altura funcionam como uma barreira contra o vento (KUMAR et al, 2022) e as mais largas tendem a possuir maior número de cladódios.…”

No Semiárido Brasileiro, espécies do gênero Opuntia detêm relevante importância como reserva forrageira. No entanto, algumas pragas, como Dactylopius opuntiae, representam um entrave para essa cultura. Nesse sentido, avaliou-se 15 acessos de Opuntia com resistência esta praga, quanto aos aspectos morfológicos, produtivos e de trocas gasosas. As avaliações foram feitas 180 dias após o plantio, sendo mensuradas variáveis como altura e largura de plantas, índice de área de cladódio, sobrevivência, produtividade de matéria fresca, taxa de captação de CO2, eficiência instantânea de uso da água, eficiência intrínseca do uso de água e eficiência de carboxilação instantânea. Os resultados demonstraram elevada variabilidade entre os acessos para as variáveis morfológicas e produtivas. A análise de componentes principais evidenciou forte associação entre as características morfológicas e a taxa de captação de CO2, eficiência instantânea de uso da água, eficiência intrínseca do uso de água e eficiência de carboxilação instantânea. Neste estudo foram identificados acessos de Opuntia com características superiores, como os acessos 48, 49, 75, 91 e 100.

Nanostructures have been used for various biomedical applications due to their optical, antibacterial, magnetic, antioxidant, and biocompatible properties. Cancer is a prevalent disease that severely threatens human life and health. Thus, innovative and effective therapeutic approaches are urgently required for cancer. Photothermal therapy (PTT) is a promising approach to killing cancer cells. In this investigation, we developed a low‐cost, simple, green technique to fabricate molybdenum trioxide nanostructures (MNs) using Opuntia ficus‐indica mucilage as a template. Moreover, the MNs were functionalized with folic acid (FA) for cancer PTT. The X‐ray diffractometer results revealed that the prepared MNs have an orthorhombic crystal phase. The transmission electron microscope image of MNs shows a flake shape with 20–150 nm diameter. The cytotoxicity of MNs and FA‐conjugated MNs was studied in vitro. These cell viability assay results suggested that fabricated MoO3 nanostructures reduced 25% of cell viability in MCF‐7 cells, even at high doses. However, even with high‐dose treatment, FA/MNs do not cause significant cell death. Acridine orange/ethidium bromide (AO/EB) staining revealed DNA and chromatin condensation in MCF‐7 cells exposed to MNs. Overall, the in vitro study results suggested that FA/MNs have excellent biocompatibility, which applies to biomedical applications. MNs dispersion temperature gradually increases from 26 to 58°C under 808 nm laser irradiation. We found significant mortality rates after NIR irradiation in MNs‐ or FA/MNs‐treated MCF‐7 cells. These findings suggest that FA/MNs can be used as an effective photothermal agent to treat breast cancer.
