摘要
以从荷兰引种到沈阳地区的16个郁金香品种为试材,对露地越冬后的生物学性状进行观察和统计,研究郁金香生长发育的性状。结果表明:在沈阳地区大多数的郁金香品种在3月下旬萌发,4月中旬前后各品种基本能用肉眼观察到花蕾,始花期集中在4月15—22日。品种‘Senora’、‘Cum Laude’、‘Ravani’、‘Canasta’、‘Mount Tacoma’和‘Black Parrot’的花期较长,达到15d或以上,是布展和城市绿化的理想品种。品种‘Golden Apeldoom’、‘Triumph Blue’和‘Purpled Dream’株高都超过了40.0cm,可以用作切花生产。品种‘Red Baby Doll’、‘Uncle Tom’和‘Canasta’的植株高度均在20.0cm以下,是理想的盆栽品种。品种‘Blue Parrot’的繁殖能力最强,总繁殖率达到620.0%,品种‘Crystal Beauty’和‘Crystal Star’,开花球繁殖率最高,分别为220.0%和200.0%。
In this experiment,growth traits of 16 tulip cultivars wintered outdoor were observed and analyzed to study the growth and developemnt traits of tulip. The results showed that in Shenyang area, the date of bud coming up of most of 16 tulip cultivars was in late March. Their flower buds appeared in the middle of April,blooming date between April 15 and April 22. Cultivars of ＇Senora＇. ＇Cum Laude＇. ＇Ravani＇. ＇Canasta＇. ＇Mount Tacoma ＇ and ＇Black Parrot＇ showed longer blooming period of 15 days or more, they were the ideal cultivars for urban landscaping. The plant height of ＇Golden Apeldoom＇ .＇Triumph Blue＇ and ＇Purpled Dream＇ was more than 40 cm,which could be used as cut flower. Cultivers of ＇ Red Baby Doll＇. ＇Uncle Tom＇ and ＇Canasta＇ were conducive to pot culture because of their less than 20 cm plant height. ＇Blue Parrot＇ showed the strongest reproductive capacity with the gross reproduction rate of 620 %. Cultivars of ＇Crystal Beauty＇ and ＇Crystal Star＇ showed the highest reproduction rate of bulbs that could form flower,with the rate of 220% and 200% respectively.
