Heatmap of the correlation coefficients between five Asparagaceae species. Darker colors denote stronger positive correlations; lighter shades indicate weaker correlations. CE = catechin equivalent; GAE = gallic acid equivalent; QE = quercetin equivalent.

Scientists found significant variability in the phytochemical content and genetic relationships among five Asparagaceae plant species. Furcraea watsoniana and Yucca filamentosa stand out for their high levels of bioactive substances.

Photographs of Cannabis sativa mother plants just after [A, C; 112 days after planting (DAP)] or just before severance (B, D; 133 DAP) as well as a photograph of an apical stem cutting (E), for genotype ‘Original Blitz’ (A, B) and genotype ‘King Harmony’ (C, D, E).

Propagation via stem cuttings is key in medicinal cannabis production, yet remains understudied. Researchers explored how mother plant age and light intensity during cultivation and propagation influence rooting success and cutting development.

Summary of processes in soils, crops, and the environment that influence cadmium (Cd) accumulation in cropland soils, which, in turn, can affect concentrations of Cd in crops grown on the soil and the bioavailability of Cd in those crops. Although Cd added to the soil surface remains in the tillage depth for centuries, naturally Cd-mineralized soils can be high in Cd throughout the A, B, and C horizons down to the parent materials below the C horizon.

Cadmium is a nonessential element with potential adverse health consequences. New review uses spinach and carrots to illustrate the plant and soil factors that affect the concentration of Cd in the crops and potential mitigation strategies.

Phosphorus (P) levels (A) standard plant leaf P content, (B) soil P content, (C) leaf sap P concentration from New Age Laboratories, and (D) leaf sap P concentration from NovaCropControl. The red line represents the bottom of the optimum range, and the green line represents the top of the optimum range of the respective nutrient from each methodology. In sap analysis graphs, + represents nutrient excess and – represents nutrient deficiency, based on nutrient mobility.

Can sap analysis reveal citrus nutrientional needs better than conventional methods? UF/IFAS tested it on 'Ray Ruby' grapefruit in Florida 🍊Results show promise and pitfalls. #HortTechnology https://doi.org/10.21273/HORTTECH05697-25
