Alpha diversity richness among cultivars, water treatments and tissues. (A) Shannon diversity index for maternal and offspring seed samples. (B) Shannon diversity index for root samples. (C) Chao1 diversity index for maternal and offspring seed samples. (D) Chao1 diversity index for root samples. Differences among cultivars and water treatments for each tissue were analysed through ANOVA and Tukey post-hoc test, at p-value < 0.05
