The Role of Salicylic Acid in Salinity Stress Mitigation in : A Medicinal Species Native to South America.

Salicylic acid (SA) is a bioregulator well-known for mitigating salinity damage in plants. However, no studies have examined the interaction between SA and salinity in , a species rich in bioactive molecules. Therefore, we aimed to evaluate the effect of SA application on under different salinity levels.

Hydrogen peroxide and salt stress in radish: effects on growth, physiology, and root quality.

Unlabelled: Hydrogen peroxide (HO) plays a central role in responses to salt stress, a major abiotic stress that impacts crop yield worldwide. Despite the evidence that HO mitigates salt stress and improves post-harvest quality on several species, its effects on radish were not investigated so far. Thus, the objective of this study was to evaluate the exogenous application of HO on salt stress mitigation of radish growth, physiology, and post-harvest quality.

In Vitro Propagation of "Salsaparrilha" [Herreria salsaparrilha Mart. (Asparagaceae)]: An Antisyphilitic Medicinal Species.

An efficient procedure for in vitro propagation of Herreria salsaparrilha Martius was established from single-node explants (fourth and fifth nodes from apex to the base) derived from donor plants maintained under shading-house conditions. After surface sterilization, explants are inoculated in test tubes containing 15 mL of Murashige and Skoog (MS) medium without growth regulators. Cultures are maintained under 35 μmol m s irradiance, a 16/8-h light/dark light regime, at 26 ± 2 °C.

Salicylic Acid and Water Stress: Effects on Morphophysiology and Essential Oil Profile of .

The exogenous application of bioregulators, such as salicylic acid (SA), has exhibited promising outcomes in alleviating drought stress. Nevertheless, its impact on culantro ( L.) remains unexplored.

Irrigation level and substrate type on the acclimatization and development of mandacaru (Cereus jamacaru DC.): an emblematic cactus from Brazilian semiarid region.

Mandacaru is a cactus with great socioeconomic potential, but lack of information about its cultivation hinders its domestication. Here, we aimed to evaluate the acclimatization and vegetative development of mandacaru under different substrates and irrigation levels. For this, seeds inoculated in vitro were grown for 120 days, being transplanted to pots containing four types of substrate (S1-caatinga soil + gravel; S2-washed sand + organic matter + soil + charcoal; S3-washed sand + cattle manure + soil + sand; S4-commercial organic substrate).

Water stress and exogenous carnitine on growth and essential oil profile of L.

Unlabelled: Water stress influences plant growth and metabolism. Carnitine, an amino acid involved in lipid metabolism, has been related to responses of plants to abiotic stresses, also modulating their metabolites. Culantro ( L.

Drought stress mitigation by foliar application of L-carnitine and its effect on radish morphophysiology.

Unlabelled: Drought is the major abiotic stress limiting crop production worldwide, with drought events being expected to be harsher and more frequent due to the global warming. In this context, the development of strategies to mitigate the deleterious effects of drought, such as the use of biostimulants, is imperative. Radish is a globally cultivated root vegetable, with high nutritional and phytochemical value.

Salicylic acid mitigates the effects of mild drought stress on radish () growth.

Water deficit is the most critical factor limiting plant growth and production and salicylic acid (SA) has potential for stress mitigation in plants; therefore, we evaluated the effect of SA on radish (Raphanus sativus L.) growth and ecophysiology under water deficit. Plants were sprayed with SA (100μM) or water (control), and irrigated at 80% (W80), 60% (W60), 40% (W40), and 20% (W20) of field capacity.

Irradiance-regulated biomass allocation in Raphanus sativus plants depends on gibberellin biosynthesis.

Gibberellin has been proposed to increase leaf elongation in radish (Raphanus sativus L.) plants, which is associated with decreased tuber growth. Since light intensity can control growth through interaction with gibberellin, investigation of the effect of gibberellin levels on the growth of radish plants would be a step forward towards unraveling factors that underlie biomass accumulation and allocation in response to irradiance levels.
