Studies on adaptability of seven species of Gesneriaceae plants to light intensity
HubeiAgricultural Sciences2020, 59(3): 102-107
ABSTRACT
The adaptability of the light intensity of the Gesneriaceae plants was studied to improve the quality of potted Gesneriaceae plants and promote its reasonable application in gardens.The physiological indicators such as malondialdehyde, soluble protein and chlorophyll content under different shading conditions of sevenGesneriaceae plants,including Primulina fimbrisepala,P.eburnea，Primulina‘Silver Antler’,Hemiboea gracilis,Briggsia mihieri,Lysionotus pauciflorusand Pseudochirita guangxiensis var. glauca were measured, and the growth was observed．Comprehensive analysis and comparison show that all 7 species of Gesneriaceae family have strong negative tolerance and can grow normally under the conditions of light intensity of 2000~8000lx．From light to strong,the adaptability to the light is Lysionotus pauciflorus,Pseudochirita guangxiensis,Primulina‘Silver Antler’, Briggsia mihieri，Primulina fimbrisepala,Hemiboea gracilis,Primulina eburnea.

Notes: The genus, Briggsia, was canceled and the species, previous B. mihieri (Franch.) Craib, was changed its place to another new genus, Glabrella Mich.Möller & W.H.Chen. The new scientific name is G. mihieri (Franch.) Mich.Möller & W.H.Chen.
