【摘要】 ‘中梗1号’、‘中梗2号’和‘中梗3号’是利用雄性不育系GP1BC1-12-11配制选择出的桔梗一代杂种,生长势强,根部药材产量高,抗立枯病。2年生‘中梗1号’桔梗总皂苷含量2.45%,桔梗皂苷D含量0.092%,侧根少,适于饮片加工。‘中梗2号’桔梗总皂苷含量2.89%,桔梗皂苷D含量0.097%,适于提取加工。‘中梗3号’桔梗总皂苷含量2.59%,桔梗皂苷D含量0.077%,粗纤维含量低,适于食用和药用。更多还原

【Abstract】 The new Chinese bellflower cultivars’Zhonggeng 1’,’Zhonggeng 2’and’Zhonggeng 3’were the first generation hybrids which were developed using the cytoplasmic male sterile line.The hybrids have strong growth vigor with high yield of medicinal roots and seedling blight resistance.For the two-year harvested roots,the content of the total saponins and saponin D were 2.45% and 0.092% of ’Zhonggeng 1’,2.89% and 0.097% of’Zhonggeng 2’,2.59% and 0.077% of’Zhonggeng 3’.’Zhonggeng 1’with fewer lateral roots was suitable for the use of decoction pieces processing.’Zhonggeng 2’with higher saponins content was suitable for the use of extraction processing.’Zhonggeng 3’with lower crude fiber content was suitable for both edible and medicinal usage.更多还原
