Comparative analysis to different ecological conditions on main growth period and nutritional components of Heraclenm dissectum
Abstract：Based on the 6 accumulated temperature zone of Heilongjiang in different ecological conditions represent natural habitats under the mountain Heraclenm dissectum as the experimental materials,based on the determination and analysis of its character index and the main growth period of the field investigation and comparison of nutritional components,of different ecological conditions on the growth and nutrient content of Heraclenm dissectum effect,provide the basis for the selection of ecological conditions according to different production purposes.The results showed that with the decrease of temperature,the annual average temperature in ecological conditions and other factors,the phenophase and growth period of Heraclenm dissectum were shorten.The growth period of Heractenm dissectum in Dongning ecological condition was 114 d,which was 20 d longer than that of Huyuan,the difference of the growth period was significant.The content of polysaccharides,soluble sugar and fat in leaves were increased,and the content of soluble protein was decreased.The ecological conditions of Dongning were beneficial to the accumulation of flavonoids and saponins in Heraclenm dissectum,and the accumulation of coumarin compounds in Heraclenm dissectum is favorable to the ecological conditions of Hailin.
