Abstract:
Taking the seeds of Bletilla striata as materials,three carbon sources (glucose,sucrose and soluble starch) and two levels (30 g/L and 60 g/L) were choosen for randomized block design.Statistics analysis of seed germination and seedling growth were used to select appropriate carbon sources.The results showed that glucose and soluble starch promoted the embryo enlargement and greening,and no significance between two factors.Sucrose significantly increased the plant height,length and width of leaves,fresh weight,and root length.Soluble starch (30 g/L) was used for seed germination as best source,and sucrose as best source for seedling growth.The findings suggested that appropriate carbon source was very useful for seed germination and seedling growth of Bletilla striata.
