Influence of light intensity and water content of medium on total dendrobine of Dendrobium nobile Lindl
Journal Title: Asian Pacific Journal of Tropical Medicine - Year 2017, Vol 10, Issue 11
Abstract
Objective: To ascertain the influence of light intensity and water content of medium on the total dendrobine of Dendrobium nobile (D. nobile). Method: The principal component analysis combined with total dendrobine accumulation was conducted to assess the yield and quality of D. nobile in all treatments. In the experiment, D. nobile plants were cultivated in greenhouse as tested materials, and complete test of 9 treatments was adopted with relative light intensities 75.02%, 39.74%, 29.93% and relative water content of medium 50%, 65%, 80%. The plants were treated in June and harvested till December. Indexes including agronomic traits, fresh weight and dry weight of stem and leaf, ash content, extract, and dendrobine were measured. Results: Under the light intensity treatments of 75.02% with50%, 65%,80%water content of medium, the basal stems of plants were comparatively thicker with more leaves, and the fresh weight and dry weight of stems and leaves were significantly higher than other 6 treatments. Leaves in all treatments contained dendrobine. Under the light intensity treatments of 75.02% with 50%, 65%, 80%water content of medium, dendrobine content of leaves was lower while dendrobine contents of other treatments were more than 0.60%. After comprehensive assessment through the principal component analysis and total dendrobine accumulation, the results showed that 3 treatments with relative light intensity of 75.02% ranked the top three. Conclusions: In brief, the moderately strong light intensity and water content of medium from low to medium can facilitate the growth and yield of D. nobile plants, while light intensity from moderately weak to weak can enhance the dendrobine content.
