improved significantly. However, little is known about the germination and vigour of seeds
harvested from mother plant grown under elevated [CO 2], particularly in rice. Since elevated
[CO 2] influences the physiological functions of crop and seed development process, it is
expected that such changes will alter the quality of the seed. To test this hypothesis, rice
crop (IR 36) was grown in open top chamber (OTC) with varying [CO 2][410 (ambient), 510 …
