Response of Epidendrum Ibaguense (orchidaceae) to the application of lime rates to the pot

Abstract

In the best cultivation methods of orchids, in particular of the genus Phalaenopsis, liming is a common practice. The objective of this study was to evaluate the influence of lime rates (0.0; 1.0; 2.0; 3.0; 4.0; and 5.0 g dm -3 of substrate) applied to the cultivation substrate (xaxim) on the growth of Epidendrum ibaguense seedlings. In a greenhouse, 1-L plastic pots filled with 0.8 dm 3 of xaxim were irrigated such that no leachate was lost during the experiment. N, P, K, Ca, Mg, S, Fe, Zn, B, and Mn contents in roots, stems and leaves were measured. Leachate was collected by applying a sufficient water volume to obtain 25 mL from each pot. Fourteen days after lime application of 3 g dm -3 , the pH of the collected leachate reached values above 7 and a value of 6.29 with the highest lime rate at the end of the experiment. The lime rate did not influence plant height, probably due to a Zn deficiency at high pH levels and a Ca deficiency in the control. Nevertheless, there was a large increase in leaf production, for number as well as for dry matter mass. There was no statistical difference between treatments in root dry matter production. Maximum dry matter production was obtained at a lime rate of 4.09 g dm (0,0; 1,0; 2,0; 3,0; 4,0 e 5,0 g dm -3

Nutrient Concentration in Vegetative Organs of the Orchid <i>Laelia anceps</i> subsp. <i>anceps</i> Based on Mineral Fertilization and Biofertilization

“…anceps. Rodrigues et al (2010b) reported a higher dry matter yield, number, and weight of leaves of Epidendrum ibaguense with different amounts of lime. Hsu et al (2010) reported that supplementation with calcium nitrate (300 mg·L −1 ) improved the quality of the inflorescences of Oncidium ʻGower Ramseyʼ.…”

PYROLIGNEOUS LIQUOR EFFECT ON IN AND EX VITRO PRODUTION OF Oeceoclades maculata (Lindl). Lindl.1

“…Zinc plays an important role for seedling metabolism and growth; according to some authors, its availability must be increased in culture medium for an enhancement of orchid in vitro growth (RODRIGUES et al, 2010). In this study, pyroligneous liquor may have acted as a nutrient source for protocorms due to its concentration of macro and micronutrients (Table 1).…”

An Updates on Chrozophora Tinctoria for Its Medicinal Values

“…Fertilizers inhibited growth and development of the root while stimulating the stems and leaves. The plant grows under various conditions at altitudes of 0-1650 meters [21].…”
