Abstract:: Taking Chinese celery seeds with space flight as the test materials，celery seeds without space flight as control，using completely randomized design of two factors，the change of greenhouse cultivation of biomass，and conventional celery seed chlorophyll，MDA，soluble sugar，soluble protein and proline content physiological index were compared and studied.The results showed that the biomass of treatment by space flight had a higher level comparing with CK (P<0.01).Two treatments in plant height were significantly higher than those in the control group (P<0.01).Dry weight extremely significantly increased comparing with CK.Leaf area in control were significantly lower than treatments (P<0.01).There were obvious differences in MDA，soluble sugar，soluble protein，proline and chlorophyll between treatments and CK.Prophase chlorophyll a，chlorophyll b and chlorophyll had little differences.Late in process of breeding it made a great difference between chlorophyll a and chlorophyll b.Chlorophyll a was sensitive to space-ray.
