Abstract

Growth analyses were carried out on young plants of 15 genotypes, grown initially at 19/14 degrees C day/night temperatures for an 8 h day at low light intensity and subsequently at the night temperatures of 6, 10 and 14 degrees C. Significant genotypic differences occurred for relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), specific leaf area (SLA) and leaf weight ratio (LWR). RGR, LAR and SLA increased and LWR decreased at higher night temperatures. A strong negative correlation was observed between NAR and LAR and NAR and SLA whilst a positive correlation was noted between LAR and SLA. Plant weight was strongly influenced by seed size.
