  1. Flower stem length was estimated from the junction of the stem and bulb to the start of the receptacle, while the relative stem elongation was calculated with respect to the measurement 3 dac (100%), as described in “Materials and methods”. Different letters in the same column indicate statistical differences among cultivars according to the LSD test with P ≤ 0.05. (3 dac P =  < 0.0001; 5 dac P =  < 0.0001; 7 dac P =  < 0.0001; 9 dac P =  < 0.0001; 11 dac P =  < 0.0001). In the case of stem length, data are means ± SD of six biological replicates.
