Abstract This study aimed to explore the cold tolerance of two cultivars of Dendrobium officinale (MG1, MG2) grown in different regions of China. Under -2°C
incubation, cultivar MG1 remained active after 3 d, and continued to grow after
returning to room temperature. However, MG2 could only maintain its activity
after 2 d treatment at −2°C, and the seedlings died with the low temperature treatment time. Investigation of the characteristics of the plants grown in the south
(Hangzhou) or north (Zhengzhou) of China indicated that the leaves of MG1 also
had reduced stomatal density, the highest thickness, and a compact microstructure. The… More >
