郁金香引种栽培研究

调查比较了荷兰4个郁金香品种在目光温室栽培条件下的植物学特性、物候期和生长发育规律.结果表明:品种Large Copper的种球高度和花径均最小,茎上白色柔毛最长;品种Toronto的显著特征是种球的膜质鳞片为桔红色,无光泽,叶片上有红褐色条纹,花被片基部为黑色舌形;品种Pink Impression植株高,花大,叶片长而宽,叶缘有短毛.沈阳地区郁金香在日光温室12月中旬萌芽,2月下旬至3月上旬现蕾,3月上、中旬为盛花期,花期为1周左右.但品种Large Copper在1月中旬才萌芽,花期达2周.品种Apricot Beauty在盛花期生长最快,Large Copper从现蕾到末花迅速生长,Toronto的旺盛生长期为展叶至始花期,Pink Impression萌芽后期到展叶生长最快.

Introduction and Cultivation of Tulip

Four tulip cultivars were introduced from Holland.Their botanical characteristics,phenological periods and growth in greenhouse were investigated and compared.The results showed that bulb height and flower size of 'Large Copper' were least,with longest white short soft hair on stem.Obvious characteristics of 'Toronto' were nacarat and lackluster membranous bulb scales,leaves with rufous stripe and base of perianth shape and colour.Obvious characteristic of 'Pink Impression' were taller plantlet,bigger flower,taller and wider leaves and edge of leaves with short hair.Germination period of tulip was about 20th December,Visible bud period was from the last ten days of February to the first ten days of March.Florescence was in the first twenty days ofmarch with about a week generally.But germination period of 'Large Copper' was in themiddle ten days of January.Florescence of 'Large Copper' was up to two weeks.The growth of 'Apricot Beauty' was fast during full blooming period.The rapid growth of Large 'Copper' was from visible bud to terminal of blooming,but which of 'Toronto' was from leaf-spread to beginning of blooming,and which of 'Pink Impression' was from the end of germination to leaf-spread period.
