Summary Deserts represent key carbon reservoirs, yet as these systems are threatened this has implications for biodiversity and climate change. This review focuses on how changes affect desert ecosystems, particularly plant root their impact mineral nutrient stocks. Desert plants have diverse architectures shaped by water acquisition strategies, affecting biomass overall Climate change can disrupt communities, with droughts impacting both shallow deep‐rooted groundwater levels fluctuate....
Abstract Drylands, comprising semi‐arid, arid, and hyperarid regions, cover approximately 41% of the Earth's land surface have expanded considerably in recent decades. Even under more optimistic scenarios, such as limiting global temperature rise to 1.5°C by 2100, semi‐arid lands may increase up 38%. This study provides an overview state‐of‐the‐art regarding changing aridity arid with a specific focus on its effects accumulation availability carbon (C), nitrogen (N), phosphorus (P)...
Phoebe zhennan (Gold Phoebe) is a threatened tree species in China and valuable important source of wood bioactive compounds used medicine. Apart from anthropogenic disturbances, several biotic constraints currently restrict its growth development. However, little attention has been given to building adaptive strategies for conservation by examining morphological physio-biochemical responses drought stress, the role fertilizers on these responses. A randomized experimental design was...
Alnus cremastogyne, a broad-leaved tree endemic to south-western China, has both commercial and restoration importance. However, little is known of its morphological, physiological biochemical responses drought phosphorous (P) application. A randomized experimental design was used investigate how affected A. cremastogyne seedlings, the role that P applications play in these responses. Drought had significant negative effects on growth metabolism, as revealed by reduced biomass (leaf, shoot...
Plants of Pinus taeda L. from each four families were fertilized with nitrogen (N), phosphorus (P) or N + P at planting. The H family had the highest growth in dry mass while L lowest growth. Measurements plant hydraulic architecture traits performed during first year after Stomatal conductance (gs), water potential predawn (Ψpredawn) and midday (Ψmidday), branch conductivity (ks kl) shoot (K) measured. One planting, weight partitioning all aboveground organs was performed. Phosphorus...
Perennial trees are often stressed by drought more than once during their life cycle. Our study exposed three-month-old Alhagisparsifolia, with (drought-primed) or without (nonprimed) prior stress to subsequent for two months, aiming reveal whether pre-exposure could enhance seedling resistance and investigated possible underlying mechanisms. Root biomass, leaf relative water content, chlorophyll a, carotenoids were significantly higher in drought-primed nonprimed seedlings. They also had...
Eucalyptus grandis is the most widely planted tree species worldwide and can face severe drought during initial months after planting because root system developing. A complete randomized design was used to study effects of two water regimes (well-watered water-stressed) phosphorus (P) applications (with without P) on morphological physio-biochemical responses E. grandis. Drought had negative growth metabolism grandis, as indicated by changes in traits, decreased net photosynthetic rates (Pn...
Abstract Eucalyptus grandis is a globally important tree crop. Greenhouse-grown seedlings often face water deficit after outplanting to the field, which can affect their survival and establishment severely. This be alleviated by application of superabsorbent hydrophilic polymers (SAPs). Growth promoting bacteria also improve crop abiotic stress tolerance; however, use in trees limited, partly due difficulties viability loss. In this work, we evaluated improvement drought tolerance E....
Fast development of seedling leaf area is a relevant trait in order to increase early resource acquisition. The use semi-dwarf genotypes wheat has decreased vigour modern cultivars. We studied 20 cultivars cropped Argentina, and our main objectives were: (i) analyse the genotypic variability vigour; (ii) study morphological traits that can be good indicators vigour, such as seed mass, width, specific area; (iii) determine whether increased dry mass allocation roots impacts negatively on...
The stoichiometry of carbon, nitrogen, and phosphorus (C:N:P) among leaves, stems, roots reflects trade-offs in plants for acquiring resources their growth strategy. widely distributed plant Alhagi sparsifolia is an ideal species to study the ecological different organs response availability nutrients water desert ecosystem. However, which most sensitive environmental conditions still unclear. To answer this question, we collected samples soils including not only aboveground leaves but also...
More efficient use of soil resources, such as nitrogen (N) and phosphorus (P), can improve plant community resistance resilience against drought in arid semi-arid lands. Intercropping legume non-legumes be an effective practice for enhancing P mineralization uptake, nutrient status. However, it remains unclear how intercropping systems using desert species impact soil-plant fractions they affect N water uptake capacity. Alhagi sparsifolia (a legume) Karelinia caspia non-legume) are dominant...
