Effects of preconditioning and temperature during germination of 73 natural accessions of Arabidopsis thaliana.

ABSTRACT:

Background and aims

Germination and establishment of seeds are complex traits affected by a wide range of internal and external influences. The effects of parental temperature preconditioning and temperature during germination on germination and establishment of Arabidopsis thaliana were examined.

Methods

Seeds from parental plants grown at 14 and at 22 degrees C were screened for germination (protrusion of radicle) and establishment (greening of cotyledons) at three different temperatures (10, 18 and 26 degrees C). Seventy-three accessions from across the entire distribution range of A. thaliana were included.

Key results

Multifactorial analyses of variances revealed significant differences in the effects of genotypes, preconditioning, temperature treatment, and thei
