Fig. 1From: Early cold stress responses in post-meiotic anthers from tolerant and sensitive rice cultivarsSpikelet fertility in cold-stress tolerant and sensitive cultivars. Spikelet fertility as the percentage of filled/empty spikelets after grain maturation is shown. NB, Nipponbare. Bars represent mean ± SEM of at least two biological replicas. Asterisks indicate statistically different mean values compared with the control (Student’s t-test, p < 0.05)Back to article page
