  • For quantification of inflorescence characters, the sample size was normal 13, Bif1/+ 12, Bif1/Bif1 9, spi1 14, Bif1/+; spi1/spi1 14, and Bif1/Bif1; spi1/spi1 9. For quantification of vegetative characters, the sample size was Normal 11, Bif1/+ 17, Bif1/Bif1 9, spi1 4, Bif1/+; spi1/spi1 6, and Bif1/Bif1; spi1/spi1 6.

  • a Value is significantly different from normal, P < 0.05.

  • b Value is significantly different from Bif1/+ and Bif1/Bif1, P < 0.05.

  • c Value is significantly different from spi1, P < 0.05.
