【摘要】 通过对北京市植物园露地栽培的35个郁金香品种的物候及生长发育特性的观测分析,发现萌动及展叶最早的品种为‘构思的印象’,萌动最晚的为‘和平王子’、‘春绿’、‘哈密尔顿’,两者相差约20天,从萌动到植株枯黄,各品种生长期天数从56到75天不等。‘杏色印象’、‘构思的印象’和‘黄普瑞斯玛’始花期最早,在4月9～10日,‘哈密尔顿’、‘猩红天空’在4月28～29日才始花,差异近20天。大多数品种在4月20日左右达到盛花期,花期达14～20天。郁金香生长迅速,‘王朝’、‘猩红天空’、‘羞涩小姐’高度超过70～80cm,‘和平王子’、‘黄飞翔’、‘哈密尔顿’等少数品种株高不足50cm,而且‘黄飞翔’和‘羞涩小姐’整齐度较好,植株间高度差约2cm,‘法国之光’、‘哈密尔顿’、‘猩红天空’等整齐度较差,植株间高度差大于8cm。花瓣较大的品种有‘法兰西奥斯’、‘金色牛津’、‘领袖’、‘王子’等,大小8cm×5 cm左右,花瓣较小的品种有‘卡奈沃德乃斯’、‘天使’、‘雪莉’等,大小5 cm×4 cm左右。文中还对生长发育进行了分析和讨论。更多还原

【Abstract】 Based on the phenological observation of 35 tulip cultivars that were planted in Beijing Botanical Garden,the results showed that the earliest sprouting cultivar was‘Design Impression’,and that the latest sprouting cultivars were‘Spring Green’ and‘Hamilton’.Their difference was ca.20 days.The growth period ranged from 56 to 75 days depending on the cultivar.The earliest blooming （before April 10th） cultivars were‘Apricot Impression’,‘Design Impression’ and‘Yellow Purissima’, and the latest blooming（April 28th/29th） cultivars were‘Hamilton’ and‘Sky High Scarlet’. Their difference was ca.20 days.Many cultivars had best flowers around April 20^th and lasted 14-20 days.Tulips grew quickly,and‘Dynasty’,‘Sky High Scarlet’ and‘Blushing Lady’ were more than 70-80 cm high,while‘Prince Irene’,‘Yellow Flight’ and‘Hamilton’ less than 50 cm high. The height difference between plants in‘Yellow Flight’ and‘Blushing Lady’ was ca.2 cm,while‘Ile de France’,‘Hamilton’ and‘Sky High Scarlet’ more than 8 cm.‘Francoise’,‘Golden Oxford’,‘Big Chief’ and‘Ad Rem’ had larger petals,around 8cm×5 cm,while‘Carneval de Nice’,‘Angelique’ and‘Shirley’ had smaller petals,around 5 cm×4 cm.In addition,the growth and development of tulips were analyzed and discussed.更多还原
