The effect of low growth temperature on Hill reaction and photosystem 1 activities and pigment contents in maize inbred lines and their F1 hybrids

Abstract

The photochemical activity of isolated chloroplasts and the content of photosynthetic pigments in inbreds and hybrids of maize stressed and non-stressed by low temperature were compared with the aim to determine genetic basis of heterosis
