摘要
以6个茄子单性结实自交系为试材,研究了自然低温和蕾期去雄及去柱头处理对其单性结实性的影响.试验结果表明,供试材料的单性结实性属于温度敏感型,在低温下表达.诱导单性结实基因表达的温度在7～15℃之间,在此温度范围内,其坐果率为88.9%～100%.蕾期人工去雄和去柱头不影响单性结实果实的正常生长发育,蕾期去柱头可用于茄子单性结实性的快速准确鉴定.
6 parthenocarpic lines of eggplant were used as material to study the effect of temperature and bud stage treatment on parthenocarpic gene expression of eggplant. As the result shows, the tested material is a kind of temperature-sensitive parthenocarpy and express this characteristic under low temperature. The temperature which induces parthenocarpic gene expression range from 7℃ to 15℃ with fruit setting rate between 88.9% to 100%. Artificial emasculation and to get ride of stigmas during bud stage do not affect normal growth of parthenocarpic fruit. Getting ride of stigmas during bud stage can be used as one of the quick and accurate ways to identify the eggplant parthenocarpy.
