[Novel application of FTIR to the analysis of sweet pepper seeds and tomato seeds with space mutation].
Comparative study of the sweet pepper and tomato seeds lines with space mutation and corresponding conventional seeds was carried out with FTIR, in an attempt to search for the influence of space environment upon mutation. The similarities among space seeds lines are: the absorbance at near 1,160-1,061 cm(-1) increased. This result shows that the stretching vibration of C-O on the structure of carbohydrates was enhanced by space mutation. The special mutations are: (1) The absorbance at 2,854 cm(-1) of space sweet pepper was enhanced, showing that the stretching vibration of CH2 was stronger; (2) The absorbance at 1,160 cm(-1) of cherry tomato seeds lines was increased notably, indicating that the stretching vibration of C-O on the structure of carbohydrates was stronger. The results show that the space environment could notably increase the carbohydrates in the tomato seeds. The space sweet pepper and tomato seeds lines, which produced similar mutation, could be influenced by microgravity in space. The special mutations are the results of the influence of universe radiation in space.
