“…Em muitos solos, a concentração de B disponível para as plantas é um fator limitante, portanto, o suprimento com fertilizantes é importante em solos deficientes, sendo a adubação geralmente realizada antes do plantio (Behera et al, 2022). A reposição adequada de B possibilita incremento na produtividade da soja resultando em semente e/ou grãos de qualidade, mesmo em solos de alta fertilidade, pois as reservas naturais de B do solo são rapidamente extraídas (Silva et al, 2018).…”

O micronutriente boro (B) é essencial ao desenvolvimento da soja, sendo assim, a adubação boratada em níveis adequados é determinante ao bom crescimento da oleaginosa, incremento na qualidade das sementes, produtividade e lucratividade. Neste trabalho tem como objetivo avaliar o efeito da aplicação de doses B em diferentes estádios fenológicos sobre a qualidade fisiológica de sementes de soja. O experimento foi conduzido na Universidade Estadual de Goiás, Câmpus Sul, UnU Ipameri, Goiás. O delineamento experimental foi inteiramente casualizado, esquema fatorial 5 x 6, sendo cinco épocas de aplicação (V0, V3, V6, V9 e R1) e seis doses de B (0, 1, 2, 3, 4 e 5 Kg ha-1), com quatro repetições. A produção de sementes de soja foi realizada na safra 2021/22. Para avaliar a qualidade fisiológica das sementes foram realizados testes de germinação e de vigor (primeira contagem de germinação, índice de velocidade de germinação, envelhecimento acelerado, condutividade elétrica e massa de 1000 sementes). Para a qualidade fisiológica de sementes de soja, a aplicação boratada nos estádios fenológicos influenciaram de forma positiva na germinação, índice de velocidade de germinação, condutividade elétrica. Para as doses de boro apenas o índice de velocidade de germinação e massa de 1000 sementes foram influenciados, mostrando a importância da aplicação de boro na cultura da soja até a dose de 3,82 Kg ha-1 de B.

Global warming in this century increases incidences of various abiotic stresses, restricting plant growth and productivity and posing a severe threat to global food production and security. Different phytohormones are produced by plants to mitigate the adverse effects of these stresses. One such phytohormone is melatonin (MEL), which, being a potential bio-stimulator, helps to govern a wide array of functions in horticultural crops. Recent advancements have determined the role of MEL in plants’ responses to abiotic stresses. MEL enhances physiological functions such as seed germination, growth and development, seedling growth, root system architecture, and photosynthetic efficiency. The potential function of MEL in stressful environments is to regulate the enzymatic and non-enzymatic antioxidant activity, thus playing a role in the substantial scavenging of reactive oxygen species (ROS). Additionally, MEL, as a plant growth regulator and bio-stimulator, aids in promoting plant tolerance to abiotic stress, mainly through improvements in nutrient uptake, osmolyte production, and cellular membrane stability. This review, therefore, focuses on the possible functions of MEL in the induction of different abiotic stresses in horticultural crops. Therefore, this review would help readers learn more about MEL in altered environments and provide new suggestions on how this knowledge could be used to develop stress tolerance.

“…MT enhances the growth-related attributes as well as the photosynthetic pigments and thus maximizes the photoassimilate production and translocation efficiency from source to sink tissues and finally the yield [114]. Khan et al [115] mentioned that in tomato plant, the number of fruits per plant, fruit yield, and quality characters (ascorbic acid, lycopene content, and β carotene) were increased in MT-treated plants.…”

Melatonin (MT), a naturally occurring compound, is found in various species worldwide. In 1958, it was first identified in the pineal gland of dairy cows. MT is an “old friend” but a “new compound” for plant biology. It brings experts and research minds from the broad field of plant sciences due to its considerable influence on plant systems. The MT production process in plants and animals is distinct, where it has been expressed explicitly in chloroplasts and mitochondria in plants. Tryptophan acts as the precursor for the formation of phyto-melatonin, along with intermediates including tryptamine, serotonin, N-acetyl serotonin, and 5-methoxy tryptamine. It plays a vital role in growth phases such as the seed germination and seedling growth of crop plants. MT significantly impacts the gas exchange, thereby improving physio-chemical functions in plant systems. During stress, the excessive generation and accumulation of reactive oxygen species (ROS) causes protein oxidation, lipid peroxidation, nucleic acid damage, and enzyme inhibition. Because it directly acts as an antioxidant compound, it awakens the plant antioxidant defense system during stress and reduces the production of ROS, which results in decreasing cellular oxidative damage. MT can enhance plant growth and development in response to various abiotic stresses such as drought, salinity, high temperature, flooding, and heavy metals by regulating the antioxidant mechanism of plants. However, these reactions differ significantly from crop to crop and are based on the level and kind of stress. The role of MT in the physiological functions of plants towards plant growth and development, tolerance towards various abiotic stresses, and approaches for enhancing the endogenous MT in plant systems are broadly reviewed and it is suggested that MT is a steering compound in directing major physiological functions of plants under the changing climate in future.
