Structural anatomy of the endosperm of three wheat varieties after 72 h of germination under the control and waterlogging treatments. a, Structural anatomy of the endosperm of ZM22, BN207 and BN607 under the control and waterlogging treatments. Bars: 500 μm. b, Length, width and ratio of the length to the width of the amyloplasts of ZM22, BN207 and BN607. L, amyloplast length; W, amyloplast width. c, Number amyloplasts in ZM22, BN207 and BN607. ZM22: Zhoumai 22, BN207: Bainong 207, BN607: Bainong 607; C_22, ZM22 after 72 h of germination under the control treatment; W_22: ZM22 after 72 h of germination under the waterlogging treatment; C_207, BN207 after 72 h of germination under the control treatment; W_207, BN207 after 72 h of germination under the waterlogging treatment; C_607, BN607 after 72 h of germination under the control treatment; W_607, BN607 after 72 h of germination under the waterlogging treatment. Each point represents the average from three samples. The error bars represent the SDs. ∗ indicates significance at p < 0.05, ∗∗ indicates significance at p < 0.01
