The seeds of Impatiens balsamina L.were treated by space mutagenesis,and heritable mutant plants with floral reversion occurring only in the apical flower were obtained in their descendant generation.An analysis of the photosynthetic traits discovered that compared with the normal plants the mutants had lower light saturation point,light compensation point and dark respiration rate and that their apparent quantum yield was approximately equal to that of the normal plants.With increasing photosynthetic radiation,intercellular CO2 concentration was reduced in both the normal and the mutant plants,in a similar extent,and stomatal conductance of the mutants varied only in a narrow extent compared with that of the normal plants.In the range of the variation in stomatal conductance of the mutant plants,mutant plants and normal plants had almost the same extent of variation in intercellular CO2 concentration and net photosynthesis rate.The above results suggested that the photosynthetic characters of the floral reversion mutant plants were quite different from those of the normal plants.
