The Influence of Bio-Organic Fertilizer on Banana Seeding Root Exudates
摘要
Abstract
Banana seedling growth and root exudates were studied by using in vitro bathing root system under the condition of the sand culture and non-inoculated pathogens (FocR4). The results showed that banana seedling was significantly promoted by bio-organic fertilizer, fresh mass increased by 19. 22％ as compared with the sterilized organic fertilizer (control). Protein, total soluble sugar, total phenolic acids and organic acids in root exudates were measured. The map of iron chromatogram was relatively simple,only oxalic acid ,malic acid and tartaric acid were found. Bio-organic fertilizer had a significant effect on protein,organic acids and total phenolic acids in root exudates, reduced the contents of total phenolic acids and total organic acids by 28.7％ and 29. 9％ respectively,increased the protein content by 38.5％ as compared with the control. The trends of malic acid was similar with protein, and the trends of oxalic acid and tartaric acid was similar with total phenolic acids, but the change of total soluble sugar was not obvious among treatments.关键词
