Abstract
The photosynthetic and respiratory responses of plants from 4 natural populations of K. cristata, preconditioned in 3 environmental regimes, were compared. Tetraploid plants had significantly higher photosynthesis activity than diploid plants, while no significant differences in dark respiration occurred between ploidy levels. Photosynthesis significantly increased, and respiration decreased, with increasing temperature of the preconditioning regime. A time-course study of 2 plant groups indicated that adjustments in phosynthetic activity were occurring up to 7 days after their environment was altered.This publication has 1 reference indexed in Scilit:
