The effects of photoperiod on floral and vegetative development of Pharbitis nil were modified by atmospheric CO(2) concentrations maintained during plant growth. Short day (SD) photoperiods caused rapid flowering in Pharbitis plants growing in 0.03 or 0.1% CO(2), while plants in long day (LD) conditions remained vegetative. At 1 or 5% CO(2), however, flower buds were developed under both the S...
