晚熟桃新品种“晚秋妃”的生物学特性研究

Study on Biological Characteristics of Late-maturing New Peach Varieties 'Late Qiufei'

以13a和8a生的"晚秋妃"和"秋红蜜"为试材,在管理水平相同的情况下,研究比较了"晚秋妃"与当地同成熟期的"秋红蜜"的生物学特性、果实品质和经济效益。结果表明:"晚秋妃"平均单果重314g,果形端正,含糖量高,糖酸比适宜,风味好,成熟期为9月末,以中长果枝结果为主;其果实大小、含糖量、糖酸比均显著高于"秋红蜜",产量和"秋红蜜"相当,1kg价格比"秋红蜜"高2元,是适合唐山乃至河北省发展的优良晚熟桃新品种。

Taking ‘Late Qiufei＇ and ‘Qiuhongmi＇ of 13 years old and 8 years old as test materials, the biological characteristics of ‘Late Qiufei＇,in the case of the same management level, compared fruit quality and economic benefits with ‘Qiuhongmi＇ which the maturity is the same as ‘Late Qiufei＇ of the local were studied. The results showed that the average weight of ‘Late Qiufei＇ was 314 g. Shape of the fruit was correct,content of sugar was high and the sugar-acid ratio was appropriate, so the flavor was very good. Maturity period of the variety was at the end of September,just between the National Day and Mid-Autumn Festival, the fruit on long or moderate branches were better. Compared with ‘Qiuhongmi＇, the size, sugar content and sugar-acid ratio were significantly higher than ‘Qiuhongmi＇, and it＇ s production was the same as ‘Qiuhongmi＇, the price was higher than ＇Qiuhongrni＇ 2 yuan per kilogram. It was a new good latematuring peach variety which had a good prospect in Tangshan city or even in Hebei province.
