| Cattleya mendelii and C. quadricolor are endemic orchids from Colombia, which have been subjected to extraction from their natural environments for commercial purposes, becoming critically endangered. However, there is no sustainable management practice for the conservation of these species. The aim of this study was to establish a protocol of in vitro culture for both species. The effects of different combinations of GA3 and NAA amending MS and KC culture media were assessed for the in vitro germination and plant growth. Plant development was assessed monthly over 120 days. A higher percentage of explant production for both species was observed with MS than KC. The higher GA3 proportion of 1.5 μM resulted in enhanced germination, while the higher... |

| Leaf morphology was measured and aerodynamical attributes as well as transpiration rates were calculated for the mangrove Conocarpus erecta from sites naturally sheltered or sites exposed to oceanic winds at Socorro Island, Mexico, and compared with those of C. erecta, Laguncularia racemosa, and Rhizophora mangle at a mainland estuary near La Manzanilla, Jalisco, Mexico. Leaves of C. erecta, 5.98 cm in length and 2.03 cm in width, were the smallest and most streamlined of the mainland mangroves. Moreover, both leaf dimensions were 32 % smaller for trees from the exposed sites on Socorro Island than on the mainland. For a given wind velocity, Reynolds numbers were 10 to 33 % lower at Socorro Island than on the mainland for leaves of C. erecta, leading to a... |
