摘　　要：调查研究了湖南西部地区人工栽培七叶一枝花的植物学形态特征及物候期。结果表明,人工栽培七叶一枝花的茎、叶等比野生植株生长高大,花期比野生提前且稍短,而果期延长。根据植株生长发育消长规律可将人工栽培七叶一枝花的物候期划分成出苗期、伸长期、展叶期、开花期、结实期、枯死期、萌芽期、越冬期等八个时期。The morphological characters and phenophase of cultivated Paris polyphylla in the Western Hunan were investigated. The results showed that the stem and leaves of cultivated Paris polyphylla are larger than that of the wild Paris polyphylla; the anthesis stage of cultivated Paris polyphylla is ahead and shorter than that of the wild Paris polyphylla; the seed stage of cultivated Paris polyphylla is longer than that of the wild Paris polyphylla. The phenophase of cultivated Paris polyphylla can be divided into eight stages, which are seedlings emergence stage, plant extension stage, leaves extension stage, anthesis stage, seed stage, aerial part death stage, germination stage and hibernation stage.
