The effect of calcium carbonate and top dressing with Peters Professional Special on the growth and flowering of Helleborus lividus Aiton

Abstract

For two years (2006 − 2007), seedlings and young plants of Helleborus lividus Aiton were grown in containers with a peat substrate, which was deacidified with calcium carbonate at the following doses: 2.5, 5.0, 7.5 and 10.0 g dm-3. The plants were divided into two groups in each variant of CaCO3 dosage, one fertilized with a solution of a lower (0.1%) and the other with a higher (0.3%) concentration of Peters Professional PL Special (15:11:29). Helleborus lividus growth in the first year of cultivation depended on the calcium carbonate dose. Taller plants, with a higher number of leaves, were produced using calcium carbonate at a dose of CaCO3 2.5-5.0 g dm-3. In the second year of cultivation good quality plants - taller, with higher numbers of leaves and shoots, were produced when grown in a substrate with 2.5-7.5 g CaCO3 per dm3. The application of solutions of various concentrations in top dressing did not have an effect on the growth of Helleborus lividus in the first year of cultivation, while in the second year taller plants, with more leaves as well as flowers and buds, were produced when applying a 0.3% fertilizer solution.

Elucidation of Shoot and Root Growth, Physiological Responses, and Quality Traits of Tomato (Solanum lycopersicon L.) Exposed to Elevated Calcium Carbonate Concentrations

“…Our findings revealed that number of leaves per plant was significantly decreased by the higher concentrations (10% and 20%). Szczepaniak et al [38] and Henschke et al [39] exposed Helleborus lividus Aiton and Helleborus orientalis Lam plants to higher concentrations of CaCO 3 and found a reduction in number of leaves per plant, although they did not find statistical differences between the treatments. Our results also showed that CaCO 3 had a positive effect on leaf Ca concentration.…”

“…The fluctuations and declines in plant height, especially evident under 5%, 10%, and 20% concentrations during incubation, may be attributed to fluctuations in soil pH and EC, impacting nutrient availability. Supanjani et al [25], Szczepaniak et al [38], Henschke et al [39], and Jessop et al [40] all agreed that higher concentrations of CaCO 3 significantly decreased plant height. Stunted growth is one of the primary symptoms in plants suffering from inadequate nutrition in calcareous soils [3].…”

“…Plants exposed to higher levels of CaCO 3 produced a lower number of flowers than the control. Nonetheless, Szczepaniak et al [38] and Henschke et al [39] findings suggested that CaCO 3 had little impact on flowering. We found that application of CaCO 3 resulted in fewer fruits per plant, along with a decrease in fruit weight and size, which is similar to the results presented by Lee and Kim [26].…”

“…Чтобы решить эту проблему, мы в Ботаническом саду имени Н.В. Цицина пересадили морозники в контейнеры, в литературе подобный опыт выращивания морозников для России еще не был описан, но есть опыт выращивания H. lividus [13].…”

Growth and flowering of Helleborus argutifolius (Viviani) grown in pots depending on substrate type

“…Horticultural producers select species with small thermal requirements and a short production cycle. For this reason, the importance of hellebores has increased recently, as different studies, including cultivation trials, have been conducted on this species [1][2][3][4][5][6]. Hellebores are herbaceous perennials in which flowering may be accelerated during a culture period of as little as 4-6 weeks in a greenhouse at a temperature of [12][13][14][15][16] o C for a very attractive season, i.e.…”
