  1. Values (mean ± standard deviation) followed by the same letter are not significantly different at α = 0.05 with the Bonferroni t-test. Twenty stigmas were used at each time in each cross, and these stigmas were randomly collected from three flowers (each flower usually had 20–35 stigmas) on three plants at each time-point. GA, ‘Guili’ (pollen receptor) × ‘Aijiangnan’ (pollen donor); AG, ‘Aijiangnan’ (pollen receptor) × ‘Guili’ (pollen donor); MQ, ‘Molingqiuse’ (pollen receptor) × ‘Qinhuaiyanzhi’ (pollen donor); QM, ‘Qinhuaiyanzhi’ (pollen receptor) × ‘Molingqiuse’ (pollen donor).
