The Ability of Silicon Fertilisation to Alleviate Salinity Stress in Rice is Critically Dependent on Cultivar

Rice, Год журнала: 2022, Номер 15(1)

Опубликована: Фев. 2, 2022

Silicon (Si) fertiliser can improve rice (Oryza sativa) tolerance to salinity. The rate of Si uptake and its associated benefits are known differ between plant genotypes, but, date, little research has been done on how the benefits, hence economic feasibility, fertilisation varies cultivars. In this study, a range cultivars was grown both hydroponically in soil, at different levels NaCl, determine cultivar variation response Si. There significant effect Si, such that alleviated salt-induced growth inhibition some cultivars, while others were unaffected, or even negatively impacted. Thus, when assessing supplementation alleviating salt stress, it is essential collect cultivar-specific data, including yield, since changes biomass not always correlated with those seen for yield. Root content found be more important than shoot protecting against salinity root level 0.5-0.9% determined as having maximum stress alleviation by A cost-benefit analysis indicated beneficial mild high-yield conditions but cost-effective low-yield production systems.

Effects of plant‐available soil silicon on seedling growth and foliar nutrient status across tropical tree species

Oikos, Год журнала: 2023, Номер 2023(8)

Опубликована: Май 5, 2023

Plant‐available silicon (Si) concentrations vary considerably across tropical soils, yet the ecological importance of that variation remains largely unresolved. Increased Si availability can enhance growth and modulate foliar nutrient status in many crop species suggesting similar effects might occur natural systems. However, how growth, macronutrient as well their stoichiometry respond to plant‐available these responses differ tree is unknown. We experimentally exposed seedlings 12 a gradient concentrations, representing 85 % found central Panama, assessed aboveground status. Furthermore, we whether higher increases P availability. Increasing led increased (by up 140%). It also 220%), it affected C N species. at species‐level only small subset two four showed significant responses. At soil‐level, remained unchanged along experimental soil gradient. Our results improve and/or number species' differently forest sites varying Si. Additionally, Si‐induced have potential affect herbivory litter decomposition. Taken together, influence plant performance unequally species, change trophic interactions, with implications for ecosystem processes.

Nitrogen availability and plant–plant interactions drive leaf silicon concentration in wheat genotypes

Abstract Estimating plasticity of leaf silicon (Si) in response to abiotic and biotic factors underpins our comprehension plant defences stress resistance natural agroecosystems. However, how nitrogen (N) addition intraspecific plant–plant interactions affect Si concentration remains unclear. We grew 19 durum wheat genotypes ( Triticum turgidum ssp. ) pots, either alone or intra‐ intergenotypic cultures two individuals, with without N. Above‐ground biomass, height [Si] were quantified at the beginning flowering stage. Nitrogen decreased for most genotypes, proportionally biomass increase. varied significantly among both increases decreases when mixed a neighbour, regardless mixture type (intra‐/intergenotype). Besides, increased was associated height. Our results suggest occurrence facilitation competition uptake from rhizosphere mixtures. Future research should identify which root traits characterise facilitating neighbours acquisition. also show that could be involved gain competition, possibly increasing light capture.

Nitrogen Fertilizer Reduction Combined with Biochar Application Maintain the Yield and Nitrogen Supply of Rice but Improve the Nitrogen Use Efficiency

Agronomy, Год журнала: 2022, Номер 12(12), С. 3039 - 3039

Excessive application of nitrogen (N) fertilizer will cause many adverse consequences in paddy fields, especially for the reduction N use efficiency. Biochar can be used to replace part rice production. A field experiment 2-year/four-season was conducted investigate effects combined with straw biochar on yield, soil fertility, and The contained six treatments: No (CK), customary (N100), 20% (N80), + (N80+BC), 40% (N60), (N60+BC). Compared N100, alone had no significant impact number tillers aboveground biomass rice, exceptfor N60 which slightly reduced grain while incorporation tended obtain higher tillers, biomass, yield compared alone. average contribution basis N80 were 5.8% 7.7%, respectively. Notably, further improved agronomic efficiency (54.5–309.4% over N100) apparent recovery (25.7–150.5% reduction. Furthermore, could not only maintain nutrition level but also improve fertility mainly by increasing pH organic matter. Therefore, integrated mineral is a feasible nutrient management measure increase ecosystem.

Short‐term exposure to silicon rapidly enhances plant resistance to herbivory

Abstract Silicon (Si) can adversely affect insect herbivores, particularly in plants that evolved the ability to accumulate large quantities of Si. Very rapid herbivore‐induced accumulation Si has recently been demonstrated, but level protection against herbivory this affords remains unknown. Brachypodium distachyon , a model hyperaccumulating grass, was exposed chewing herbivore, Helicoverpa armigera, and grown under three conditions: supplied over 34 d (+Si), not (−Si), or once began (−Si → +Si). We evaluated effectiveness each treatment at reducing herbivore performance measured Si‐based defenses phenolics (another form defense often reduced by Si). Although concentrations remained lower, within 72 h exposure Si, −Si +Si were as resistant plants. Both treatments damage growth, increased mandible wear compared −Si. After 6 h, filled cell density plants, 24 reached similar densities although decreased only occurred demonstrate with short‐term rapidly antiherbivore effectively long‐term exposure.
