Background: Cypress (Cupressus funebris Endl.) is an important tree species in the subtropics of China, it is also a major tree species for afforestation and forest land restoration under infertile site conditions. Cypress is considered to be a calcicolous tree, whose there are growth and development can be promoted significantly by exchangeable Calcium (Ca2+) in the soil. However, most of the subtropical regions have infertile acidic soils, in which Ca2+ gradually becomes a limiting element for cypress growth. Results: In this study, different concentrations of Ca2+ fertilizer were added under fertile and infertile soil conditions. Cypress clones responded differently to Ca2+ addition in different soil conditions. In the infertile soil, the addition of 3 g•kg− 1 Ca2+ advanced and prolonged the fast-growing period of seedling height growth, increased plant height and dry biomass, promoted the development of fine roots ≤ 1.5 mm in diameter, and improved accumulation efficiencies of nitrogen (N), phosphorous (P) and Ca by the roots in cypress clones; however, the addition of 6 g•kg− 1 Ca2+ inhibited height growth and root development of cypress. In the fertile soil, Ca2+ addition delayed and shortened the fast-growing period for cypress height growth, but plant height and dry biomass did not differ significantly between treatments; Ca2+ addition also inhibited the development of fine roots. The clone with fast height growth had a larger proportion of roots with a diameter ≤ 1.5 mm and achieved higher N accumulation efficiency, while Ca accumulation efficiency showed genotypic differences only in the fertile soil. Conclusions: An appropriate level of Ca2+ can be added to infertile soil to promote cypress seedling growth, and clones with fast height growth and developed fine roots can be selected for cultivation and promotion in the fertile soil without Ca2+ application.

“…Calcium (Ca 2+ ) is an essential nutrient required for plant growth and development (Kudla et al, 2010;Rashid et al, 2020). Plants generally have a Ca 2+ content ranging from 0.1-5.0%, and this element plays a role in maintaining the stability of plant cell walls, cell membranes and membrane-bound proteins, modulating inorganic ion transport and regulating various enzyme activities (Kinzel, 1989;White & Broadley, 2003;Hepler, 2005;Abbasi & Manzoor, 2013).…”

Cypress (Cupressus funebris Endl.) is an important tree species in the subtropical regions of China; it is also a major tree species for afforestation and forest land restoration under low-fertility soil conditions. Cypress is considered a calcicolous tree, and its growth and development can be promoted significantly by exchangeable calcium (Ca2+) in the soil. However, most of the subtropical regions have low-fertility acidic soils, in which Ca2+ gradually becomes a limiting element for Cypress growth. In this study, different concentrations of Ca2+ fertilizer were added under fertile soil (3 g·kg-1 NPK fertilizer added) and low-fertility soil (0 g·kg-1 NPK fertilizer added) conditions. Cypress clones responded differently to Ca2+ addition in different soil conditions. The seedling height and dry matter quality of Cypress in fertile soil were significantly greater than those in low-fertility soil, but plant height and dry biomass did not differ significantly among Ca2+ treatments. The accumulation efficiencies of nitrogen (N), phosphorous (P) and Ca all differed significantly among the Ca2+ treatments. In low-fertility soil, the addition of 3 g·kg-1 Ca2+ significantly promoted development of roots 0.5–2 mm in diameter, and both the C1 and C2 clones achieved their highest N, P and Ca accumulation efficiencies. When the Ca2+ concentration increased to 6 g·kg-1, the seedling height, dry matter quality and root development were lower than those of the 3 g·kg-1 Ca2+ treatment. In the fertile soil, the addition of Ca2+ significantly inhibited development of roots 0.5–1 mm in diameter. The highest N accumulation efficiency was achieved under the 0 g·kg-1 Ca2+ treatment, and the highest Ca accumulation efficiency was achieved under the 6 g·kg-1 Ca2+ treatment. Seedling height, root dry weight, roots 0–1.5 mm in diameter and Ca accumulation showed a significant interaction effect between NPK fertilizer and Ca2+. Therefore, Ca accumulation was more efficient in low-fertility soils. Under low-fertility soil conditions, the addition of CaSO4 can promote the root development of seedlings and advance and prolong the fast growth period of seedling height. Cypress clones can be used as an important tree species for afforestation under low-fertility soil conditions, especially under calcareous soil conditions.
