Across 33 broad‐leaved deciduous woody species, silicon enhances leaf lamina stiffness but not tensile strength whereas cellulose enhances both

Summary Silicon (Si) has been hypothesized to be a metabolically cheaper substitute for carbon‐based cell wall components support leaves. However, how the biomechanical function of Si, deposited as amorphous silica, differs from remains untested. Here, we tested hypothesis that species with higher leaf Si concentrations have stiffer but more brittle lamina. We measured mechanical properties, including modulus elasticity ( E ), tensile strength σ max and maximum strain ε tissue density, 33 deciduous broad‐leaved woody species. Multiple regression results showed concentration, cellulose concentration contributed positively negatively . By contrast, density not No significant contribution lignin properties was detected. These suggest might increase stiffness Greater decreased without increasing , which made lamina brittle. The brittleness associated explain potential cost or disadvantage using would elucidate trade‐offs between different concentrations.

Effects of leaf silicon on drought performance of tropical tree seedlings

Biology Letters, Journal Year: 2024, Volume and Issue: 20(3)

Published: March 1, 2024

Elevated leaf silicon (Si) concentrations improve drought resistance in cultivated plants, suggesting Si might also performance of wild species. Tropical tree species, for instance, take up substantial amounts Si, and varies markedly at local regional scales, consequences seedling resistance. Yet, whether elevated improves tropical forests is unknown. To manipulate concentrations, seedlings seven species were grown Si-rich -poor soil, before exposing them to the forest understorey. Survival, growth wilting monitored. did not survival any In one was reduced previously contrary our expectation. Our results suggest that does may even reduce performance, differences soil conditions influencing contribute soil-related variation performance. Furthermore, are odds with most studies on show alleviative effects crops cannot be generalized plants natural systems.

Silicon plays a crucial role in enhancing plant tolerance to various abiotic and biotic stresses, including drought, salinity, heavy metals, pathogen/pest attacks. Its application has shown promising results improving stress productivity medicinal plants. This review synthesizes findings from numerous studies investigating the mechanisms by which silicon confers tolerance, regulation of antioxidant systems, water relations, nutrient homeostasis, phytohormone signaling, stress-responsive gene expression. Additionally, it examines effects supplementation on production valuable secondary metabolites essential oils can significantly mitigate stress-induced damage plants, medicinally important species such as borage, honeysuckle, licorice, Damask rose, savory, basil, eucalyptus. The deposition cell walls provides physical reinforcement acts barrier against pathogen invasion insect herbivory.

Silicon-based anti-herbivore defense in tropical tree seedlings

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Silicon-based defenses deter insect herbivores in many cultivated and wild grass species. Furthermore, some of these species, silicon (Si) uptake defense can be induced by herbivory. Tropical trees also take up Si leaf concentrations vary greatly across within As herbivory is a major driver seedling mortality niche differentiation tropical tree understanding anti-herbivore pivotal. Yet, whether constitutive inducible forest species remains unknown. We grew seedlings eight full factorial experiment, including two levels plant-available soil (-Si/+Si) simulated treatment (-H/+H).

Phosphorus limitation occurs in many soils as a significant amount of soil P is retained forms inaccessible to plants, such bound iron (Fe) minerals. Prior studies have shown that silicon (Si) can mobilize from the binding sites Several extraction methods been developed account for different pools. Nevertheless, each those uses extractants and mechanisms extract pools soils. However, there no study comparing presence Si fertilization. We tested effect on mobility determined efficiency water, Calcium acetate lactate (CAL), Mehlich-III, Bray Kurtz extracting amorphous silica (ASi) fertilization using two contrasting characteristics. Significantly higher amounts were found at 3% ASi treatments (10 21 mg kg -1 ) compared control (4 10 water high low-yield soil, respectively just after 6 hours increased with time. This may be explained by directly competing sorption Fe Using CAL extraction, addition showed extractability.

Soil available nutrients (SANs) can be rapidly converted, absorbed, and utilized by crops. The study of the spatial distribution variation SANs, as well their response to environmental factors, is crucial for precision fertilization soil ecosystem function regulation. In this study, 220 surface-layer samples (0–20 cm) were collected in 2019 from loquat orchards mid-low mountain hilly areas central China explore effects factors (including topography, vegetation index, property, climate) on using a path analysis model. results showed that potassium (AK) ammonium nitrogen (AN) levels exhibited moderate average content, which was 123.14 mg·kg−1 119.03 mg·kg−1, respectively, whereas phosphorus (AP) displayed high content (26.78 mg·kg−1), all three SANs an uneven distributions. nugget effect values AK AN ranged 25% 75%, indicating variation, those AP <25%, suggesting variation. Furthermore, mean annual precipitation (MAP) had direct positive levels, while slope indirect through ratio index (RVI), greater impact than topography. erosion negative accelerating loss SANs.
