摘 要: 为建立小白菜开花系统,以“杭州油冬儿”、“75#”和“78#”3个品种(系)为试材,将3个品种的萌动种子分别进行10,20,30 d低温处理,观察处理后小白菜的现蕾始期、现蕾时平均叶片数、开花始期、半数花期和某一时间的现蕾率等,以研究不同春化天数对小白菜开花的影响。结果表明:促进“杭州油冬儿”和“75#”小白菜开花的最佳低温处理时间为20 d,而“78#”为30 d. 比较低温处理20 d后各品种的开花表现,发现“杭州油冬儿”和“75#”基本相同,而“78#”开花时间比“杭州油冬儿”和“75#”分别晚13 d和16 d,因此在开花研究中宜采用前2个品种(系)。

Abstract: A flowering system of pak choi was established with ‘Hangzhou Youdonger’, ‘75#’ and ‘78#’ three varieties (lines) as the materials, the germinated seeds were treated at low temperature for 10, 20, 30 d respectively. Then the initiation time and leaves number at budding, flowering initiation and half flowering time and budding rate at designated time were investigated to research the effect of different vernalization days on flowering of different varieties in pak choi. The results showed that the treatment time under low temperature for promoting flowering of ‘Hangzhou Youdonger’ and ‘75#’ was 20 d, while the ‘78#’ was 30 d. Comparing the flowering performance of three varieties after cold treatment for 20 d, ‘Hangzhou Youdonger’ and ‘75#’ were similar, while the flowering time of ‘78#’ was later 13 d than the ‘Hangzhou Youdonger’and 16 d than ‘75#’ , so the first two varieties (lines) were more suitable than the latter to the flowering research in pak choi.
