Agronomic and Quality Traits of Different Lines in Hejiang
Objective:To compare the main agronomic and quality traits of three Dendrobium nobile lines (JC-1
JC-2
and JC-3) in Hejiang
provide guidance for their production
and provide reference for breeding of new varieties. Method:The straight ruler
vernier caliper and analytical balance were used to measure the main agronomic and quality traits of D. nobile lines in Hejiang; and the contents of polysaccharides and total alkaloids in stems were determined by phenol sulfuric acid colorimetry and acid dye colorimetry respectively. Result:The results showed that one-year-old stem had the longest length in each individual plant. Stem diameter increased with the growth of life
and the two-year-old stem had the highest drying percentage. The stem length
stem fresh weight and dry weight of JC-1 and JC-2 were much higher than those in JC-3.As for quality traits
the content of polysaccharide was JC-1 (4.64%) > JC-2 (3.02%) > JC-3 (2.20%)
and the total alkaloids content was JC-3 (0.59%) > JC-2 (0.48%) > JC-1 (0.45%). However
the JC-1 with highest amount fresh weight also displayed the highest total alkaloids content by calculating its stem drying percentage. Conclusion:In conclusion
after considering the fresh weight
dry weight
the polysaccharide content and total alkaloids content all at the same time
we suggest JC-1 is the most suitable lines for planting.
