Fruit set and embryo rescue in crosses using parthenocarpic 'Mopanshi' persimmon
چکیده انگلیسی
The 'Mopanshi' persimmon is a seedless, astringent parthenocarpic cultivar that does not produce male flowers. After pollination using four non-astringent cultivars ('Zenjimaru', 'Nishimurawase', 'Okugosho' and 'Hanagosho'), seeds were produced to different degrees. 'Mopanshi' fruits pollinated with 'Zenjimaru' produced far more seeds than those pollinated with the other three cultivars. The ratio of abnormal seeds obtained from the fruits pollinated with 'Hanagosho' was higher than that obtained from the fruits pollinated with the other three cultivars. Most embryos degenerated in the early to late stages of seed development. Immature embryos were cultured in a modified MS medium (half of NO3 in MS medium + 0.4 μM BA + 0.1 μM IBA) with the greatest success (52-80%) from embryos taken from fruits 60-80 days after pollination. Seedlings failed to initiate radicles so they were transferred to dark culture conditions for 8 days or to a rooting media that contained 3% sucrose and 1% Chinese ink. The seedlings on the medium darkened with ink rooted at greater than 90.83% compared to 75.83% for dark cultured seedlings. This study demonstrated that 'Mopanshi' persimmon could be used as a female parent in crosses, but embryos needed to be moved to tissue culture conditions to continue to develop and form plantlets.
