In vitro growth of SA collection mutants under different light intensities. Two week old seedlings were cultivated on ½ MS medium under 450 μE.m⁻².s⁻¹ or 170 μE.m⁻².s⁻¹ under 12 h light /12 h dark photoperiod. (A) Rosette weight. (B) Primary root length. Data represent four biological repetitions; at least 10 seedlings were measured for each variant in each biological repetition. Central line of the boxplot represents the median occupancy, cross represents the mean, bottom and top edges of the box are 25 and 75% of distribution and the ends of whiskers are set at 1.5 times the interquartile range, asterisks indicates variants different from those for the 450 μE.m⁻².s⁻¹ intensity the same genotype, * p < 0.01, t-test.
