Effect of soil and community factors on the yield and medicinal quality of growth at different altitudes of the Funiu mountain.

Altitude and ecological factors significantly influence plant growth and the accumulation of secondary metabolites. However, current research on the impact of altitude and ecological factors on the yield and medicinal quality of is limited. This study established sampling sites in wild populations of across seven altitude ranges on Funiu Mountain.

Identification of Floral Volatile Components and Expression Analysis of Controlling Gene in 'Fengdan' under Different Cultivation Conditions.

In order to explore the release rule of floral volatile substances and the diurnal variation of different flower development stages of 'Fengdan' in potted and ground-planted conditions, dynamic headspace adsorption combined with gas chromatography-mass spectrometry(GC-MS) was used to analyze the dynamic changes in floral volatile components and contents. Quantitative real-time PCR (qRT-PCR) was used to analyze changes in flower fragrance-regulating genes , , and at different flower development stages and a daily change process at the full-blooming stage. The results show that there were differences in aroma components and contents of 'Fengdan' at different flower development stages and different time quantum of every day.
