Silicon attenuates nutritional disorder of phosphorus in seedlings of Eucalyptus grandis × Eucalyptus urophylla

BMC Plant Biology, Год журнала: 2024, Номер 24(1)

Опубликована: Май 29, 2024

Abstract Background Nutritional disorders of phosphorus (P), due to deficiency or toxicity, reduce the development Eucalyptus spp. seedlings. Phosphorus often results in stunted growth and reduced vigor, while toxicity can lead nutrient imbalances decreased physiological function. These sensitivities highlight need for precise management P levels cultivation practices. The use beneficial element silicon (Si) has shown promising under nutritional stress; nevertheless, comprehensive studies on its effects seedlings are still emerging. To further elucidate role Si varying conditions, an experiment was conducted with clonal a hybrid ( grandis × urophylla , A207) soilless system. Seedlings were propagated using minicutting method vermiculite-filled tubes, followed by treatment solution at three concentrations: deficient dose (0.1 mM), adequate (1.0 mM) excessive (10 without addition (2mM). This study assessed concentration, efficiency, oxidative metabolism, photosynthetic parameters, dry matter production. Results supply increased phenolic compounds production electrolyte leakage provided 0.1 mM P. On other hand, favored quantum efficiency photosystem II as well chlorophyll content supplemented 10 In general, attenuates disorder reducing stress, favoring non-enzymatic antioxidant system parameters . Conclusion this indicate that sensitive effect, attenuating parameters.

We aimed to clarify the nutrient allocation strategies of Cunninghamia lanceolata (CL) and Schima superba (SS) their differences in N uptake utilization under acidic stress heterogeneous N. One-year-old seedlings CL SS were cultured sands with three pH levels (pH rate 4.5, 5.5, 6.5) five different form ratios (NH4+-N NO3−-N 10:0, 7:3, 5:5, 3:7, 0:10) greenhouse.

Changes in calcium accumulation and utilization efficiency and their impact on recycling, immobilization, and export across the oil palm cycle

Oil Crop Science, Год журнала: 2024, Номер 9(3), С. 143 - 150

Опубликована: Июль 1, 2024

Effective calcium (Ca) management is crucial for optimizing oil palm cultivation and enhancing crop yield. This study aimed to gain insights into the dynamics of Ca concentration, accumulation, exportation, immobilization, recycling in various organs relative plant age. The experiment was conducted at Agropalma enterprise site northeastern region Pará State, Brazil, evaluating seven age treatments: 2, 3, 4, 5, 6, 7, 8 years old. Employing a completely randomized design with four replications. results demonstrated an age-related increase concentration petioles, rachis, arrows, male inflorescences, peduncles, fruits. Furthermore, accumulation exhibited upward trend all progressing Notably, revealed enhanced use efficiency across correlation cultivation. These findings underscore dynamic nutritional demands palm, influencing cycling, export throughout its developmental stages.

Glyphosate-based herbicide contributes to nutrient variability in forest plants

Frontiers in Forests and Global Change, Год журнала: 2024, Номер 7

In forestry, glyphosate-based herbicide (GBH) is applied to some logged areas remove deciduous and herbaceous vegetation competing with commercial coniferous trees. Glyphosate has the potential form insoluble complexes metal ions, altering bioavailability of metals in soil water. The aim this study was determine if GBH influenced concentrations available nutrients forest plants. We sampled willow ( Salix sp.), red osier dogwood Cornus sericea ), fireweed Chamaenerion angustifolium ) from forests up 12 years after applications. Across three focal species, only Mn consistently increased treatment. Significant positive correlations between nutrient glyphosate within plant tissues were found for Zn, while negative Ba, Ca, Mg, Ni. B, Mn, species significant predictors A greater number differences controls treated samples noted at year one post-treatment, showed post-treatment. analyses conducted indicate a relationship treatment resulting regimes applications, yet it complex variable. It clear that there are specific trends dataset. Due complexity, more research should be conducted, as many questions remain unanswered. Further needed disentangle both short long-term impacts widespread use products modern silviculture.

Silicon regulation of manganese homeostasis in plants: mechanisms and future prospective

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Дек. 5, 2024

Manganese (Mn), a plant micronutrient element, is an important component of metalloprotein involved in multiple metabolic processes, such as photosynthesis and scavenging reactive oxygen species (ROS). Its disorder (deficiency or excess) affects the Mn-dependent processes subsequent growth development plants. The beneficial element Si has variety applications agricultural fields for adaptation to various environmental stresses, including Mn disorder. probable mechanisms alleviation toxicity plants are summarized follows: (1) alters rhizosphere acidification, root exudates microorganisms decrease bioavailability rhizosphere; (2) down-regulates transporter gene reinforces apoplastic barriers inhibiting uptake translocation; (3) promotes deposition onto cell wall compartmentation into vacuole. Under Mn-deficient conditions, promotion absorption some remain open question. Moreover, ROS common mechanism alleviating This minireview highlights current understanding future perspectives regulation manganese homeostasis
