“…Alfalfa (Medicago sativa L.) stands asthe most extensively planted leguminous forage globally, recognized for its high nutritional value and good palatability (Li et al 2012;Mengistu et al 2022). Cultivation of alfalfa in the Loess Plateau region of northern China boosts a history spanning over 150 years (He et al 2017).…”

Background and aims The cultivation of alfalfa (Medicago sativa L.) in acidic soils in southern China poses significant challenges, primarily due to two key factors: aluminum (Al) toxicity and phosphorus (P) deficiency. This study aimed to assess the morphological and physiological responses of alfalfa roots under conditions of Al stress and P limitation. Methods A pot experiment was conducted to compare the growth and root characteristics of an Al stress-sensitive cultivar (Longzhong) and an Al stress-tolerant cultivar (Trifecta) of alfalfa in acidic soil. This was achieved by supplying six P levels (0, 10, 20, 40, 80, and 120 mg P kg-1 soil) and utilizing two soil types: limestone (pH=6.01) and yellow soil (pH=5.46), both with high soil exchangeable Al concentration (Limestone soil 397 mg/kg, yellow soil 832 mg/kg). Results Phosphorus supply alleviated Al toxicity and enhanced plant growth, but aboveground growth did not further increase when the P supply exceeded 40 mg P kg-1 soil. Trifecta exhibited higher P uptake and P utilisation efficiency, along with increased total root length, compared to Longzhong. Both alfalfa cultivars allocated more biomass to the roots to maximize P extraction from the soil. Conclusions The superior root morphological traits observed in Al-tolerant alfalfa are responsible for enhanced P uptake and biomass production in acidic soil conditions. However, excessive P application leads to a significant decline in soil pH, increased levels of exchangeable Al content in the soil, and ultimately inhibits plant growth.

The research conducted at the Shanxi Agricultural University’s Quinoa Experimental Model Base in Jinzhong, Shanxi Province, aimed to assess agronomic traits and their correlation with yield across 32 quinoa varieties. Three distinct yield categories emerged: low (≤1500 kg ha−1), middle (1500–2500 kg−1), and high (>2500 kg ha−1). High-yielding varieties demonstrated notable characteristics, including decreased plant height and increased leaf area per plant at maturity compared to low- and middle-yielding varieties. Moreover, the decline in leaf area per plant and root traits from flowering to maturity was less pronounced in the high-yielding varieties. The high-yielding varieties had a higher hardness of the stem base and middle stem by 12–13.7% and 6.3–11.5% compared to the medium- and low-yield varieties. Furthermore, high-yielding varieties indicated improvements in dry matter accumulation, decreased effective branch number, and increased main ear length and 1000-grain weight. Correlation analysis highlighted significant relationships between grain weight, yield, post-flowering senescence, and root and leaf characteristics. Structural equation model analysis revealed the negative impact of certain root and leaf traits on grain weight and yield, suggesting their importance in determining productivity. Notably, high-yielding varieties exhibited traits conducive to increased grain weight, including shorter plant height, slower root senescence, and enhanced post-flowering leaf resilience. These findings showed that understanding the relationship between agronomic traits and yield potential is crucial for optimizing quinoa production and promoting the sustainable development of this essential crop.
