Trials to detect the temperature-sensitive period. A to L, Shoot apex phenotypes of tvt1-R mutants grown in the growth chamber (36°C/26°C/13.5 h) at different growth stages. VE, V1, V2, etc. represent vegetative stages; VE represents emergence (the first vegetative stage); Vn represents where “n” is the number of leaves with collars visible. “N” represents the total number of treated plants and “f” represents the proportion of plants with no tassels. Scale bars = 15 cm. The plants were digitally extracted for comparison.
