Laelia anceps Lindl. (Orchidaceae) adaptation on phorophytes within an anthropized landscape, Amatlán de los Reyes, Veracruz, Mexico

Abstract

Objective: To determine the best phorophyte species for the adaptation of the Laelia anceps Lindl orchid. (Orchidaceae) in an anthropized landscape. Design/methodology/approach: A completely randomized experimental design with four treatments (phorophytes) was used: Swietenia macrophylla King., Fraxinus sp., Persea schiedeana Nees. and Tecoma stans. (L.) Juss. ex Kunth), with five repetitions per phorophyte and with three L. anceps orchid plants in each phorophyte. The following variables were measured: day to emergence, root length and thickness, and survival at 28 weeks after tying them in phorophytes.
 Results: Root emergence of L. anceps occurred in less time in S. macrophylla and in Fraxinus sp. at 52 and 54 days respectively; the longest root length (19.11 cm) and number of roots (32.45) were observed in S. macrophylla. However, the root thickness was greater in Fraxinus sp. (0.28 cm). After 28 weeks of establishing the L. anceps plants; 100% survival was obtained in the phorophytes S. macrophylla and Fraxinus sp., 77% in P. schiedeana and 33% in T. stans.
 Study limitations/implications: The amount of light received by L. anceps in each phorophyte was not measured.
 Findings/Conclusions: The best phorophytes for the establishment of L. anceps were S. macrophylla and Fraxinus sp. observed, the best development and strength of the roots and 100% survival at 28 weeks.

Smoothing out the misconceptions of the role of bark roughness in vascular epiphyte attachment

“…(2021), and Hernandez‐Garcia et al . (2021). However, the quantification of bark roughness in previous works has never been standardized and is problematic in many other ways (Table 1).…”

“…For example, trees with flaky or peeling bark are considered to be poor sites for attachment because plants can be easily detached together with the unstable substrate (ter Steege & Cornelissen, 1989;Hietz & Hietz-Seifert, 1995;Malizia, 2003;Wyse & Burns, 2011). 'Rougher bark' has been positively linked to epiphyte establishment since the classic works of Schimper (1888), Oliver (1930), and Went (1940), and the idea has been perpetuated in more recent works such as that from Hern andez-P erez et al (2018), Adhikari et al (2021), andHernandez-Garcia et al (2021). However, the quantification of bark roughness in previous works has never been standardized and is problematic in many other ways (Table 1).…”

Design of an interpretive trail and conservation of native orchids (Orchidaceae) in an anthropized landscape

“…The plants will reach a height of 15 cm from the base of the pseudobulb to the tip of the largest leaf and their roots will reach 10 cm in length on average, as in Lycaste aromatica (Figure 7B and 7C), as indicators of survival. Hernández-García et al (2021) reported they successfully established 30 specimens of Laelia anceps in ash (Fraxinus sp.) and Creole avocado (Persea sp.)…”
