Table 2

Overview of the controlled environment experiments at early development stages.

Experiment	Reps	Light	Temp (°C)	Duration of experiment (days)	Traits scored
Soil-based assay (cold temperature)	4	12 h, 60 W, m^−2	13/10°C	30	Emergence rate (E%), emergence index (EI), seedling length (SL), primary root length (PRL), vigor (V), shoot dry weight (SDW), and root dry weight (RDW)
Soil-based assay (normal temperature)	3	12 h, natural light	30/20°C	15	Emergence rate (E%), seedling length (SL), primary root length (PRL), shoot dry weight (SDW), and root dry weight (RDW)
Filter paper-based assay (chilling /optimum)	2	12 h, constant dark	12°C/25°C	15/7	Germination rate (%)
