TL;DR
This study examines how different phosphorus levels in two soil substrates affect the growth and physiology of Dianthus barbatus, finding that vegetable soil supports better growth than loess.
Contribution
The study identifies specific adaptive strategies of Dianthus barbatus under phosphorus stress and compares the effectiveness of two soil substrates.
Findings
Low-to-medium phosphorus treatments promoted growth in both above and underground parts of Dianthus barbatus.
Vegetable soil showed higher acid phosphatase activity and better plant growth compared to loess.
Increased chlorophyll content and acid phosphatase activity help mitigate phosphorus stress in Dianthus barbatus.
Abstract
Dianthus barbatus linn. is widely used in gardens, mainly as flower beds and flower borders. The effects of different gradients of P on the growth and root morphology of Dianthus barbatus were studied to explore its morphological and physiological responses and adaptive strategies. Hence, this study provides a theoretical basis and practical guidance for D. barbatus production. Two soil substrates, namely loess and vegetable soil, and five phosphorus concentration gradients were set; no phosphorus application was used as the control. The morphology and physiology of D. barbatus were also investigated. Low-to-medium- and low-phosphorus treatments promoted the growth of D. barbatus in the above and underground parts of the plants grown on both substrates. Chlorophyll content, flower quantity, and acid phosphatase activity in the rhizosphere soil were significantly increased in the H1 and…
